Laboratory Barstools/Equipment

When it comes to laboratory equipment and tools, we usually neglect the furniture that should be placed there. We generally think of tools, apparatus and chemicals, however, it is to be noted that sitting arrangement in the laboratory is as important as these tools and laboratory equipment. In this article, we will discuss the importance of outdoor barstools laboratory equipment and let you know basic information about these.

Bar stools are a kind of tall chair, which is often fitted with a foot rest for supporting the feet giving you stability working with liquid handling equipment, hazardous materials etc. The narrowness and height of the bar stools make them ideal for use at laboratories, bars, pubs and discos. Since 2010s, outdoor bar stools are becoming popular stuff for laboratory, usually placed on different counters and basins. In addition, since these are available in varied styles and sizes, it can easily be adjusted to laboratory of any size. There are the experiments and reactions that need enough time for monitoring and getting completed. Therefore, there must be a proper and comfortable sitting arrangement for the people working there. Outdoor barstools thud become ideal choice. The apparatus are usually placed at heights on the slabs, therefore, outdoor barstools having height feet are needed in this case for comfortable sitting, monitoring and working.

There are various kinds, construction models and materials for the outdoor barstools. These are often barstools with and without arm stets, padding and backs on the seat surface. Bar stools can range from basic wooden designs to more complex ones with adjustable height. Extra tall and extra short are common features, as well as indoor bar stools and outdoor bar stools. Some bar stools have backs, while most do not. In commercial settings, swivel and floor mounted bar stools are common. Therefore, you have a lot of variety to choose from.

Laboratory Ovens

Laboratory ovens are high forced volume thermal convection applications. These ovens usually give uniform temperatures throughout. The process applications for laboratory ovens may be for die-bond curing, annealing, drying, sterilizing, polyamide baking and other industrial laboratory applications. The normal size ranges from one cubic foot to 0.9 cubic meters, with temperature ranges over 340 degree Celsius. Laboratory ovens and all lab equipment require mandatory maintenance and safety procedures in order to function properly and are usually used in a number of configurations and applications, including the forced convention, clean rooms, inert atmosphere, horizontal airflow, and pass through. The industries that typically use laboratory ovens of different kinds include technology industry, healthcare sector and transportation industry. In engineering based laboratories, ovens are used for drying soil, rock, asphalt and concrete samples.

The laboratory oven is a vital part of your daily workflow, making sample glassware drying to the most sophisticated, with controlled heating applications. The heating and drying ovens are embedded with temperature stability and reproducibility for all required application needs. Helping to make sure maximum safety, efficiency and ease of use, these ovens are developed with sample protection as the major requirement.

General protocol ovens

These laboratory ovens carry out routine or usual applications with ease and safety. These give a good heating and drying solution for clinical, industrial and research needs. These are one of the basic types of laboratory ovens used in most of the industries.

Advanced protocol ovens

With advanced protocol ovens, you can execute multiple applications at a time, since these ovens give precise temperature uniformity with low energy consumption. These feature gravity convention technology that gives maximum temperatures as high as 330 degree Celsius.

Precision ovens

These ovens are highly performing ones in order to conduct various drying applications that need high temperature, stability and ultra-precise temperature control over a wide range of temperature, like above 325 degree Celsius.

Laboratory Sonicators

A typical modern laboratory of today is filled with a number of high tech and advanced laboratory that have made the experiments and studies execution quite easier and more accurate than ever. Laboratory sonicators are one of those tools that have been evolved as a result of advance technology availability for making laboratory equipment. In this article, we will discuss how laboratory sonicators function, what mechanism underlies its functioning and the ways it is serving a number of industrial applications.

Sonication is the process of applying sound energy in order to agitate or shake particles in the sample, for different purposes. Ultrasonic frequencies are generally used, that leads to the mechanism of the process being used, called ultra-sonication. In a laboratory, it is generally applied through ultrasonic probe or ultrasonic bath, colloquially termed as laboratory sonicator. An ultrasonic foil in a paper machine can spread cellulose fibers with more uniformity and can strengthen the paper.

Sonicators have various effects, both physical and chemical. The chemicals effects are related to understanding of the impact of sound waves on the chemical systems to which it is being applied. This is called sonochemistry when the chemical impacts of ultrasound don’t arise as a result of direct contact of molecular species. As per recent studies, it has been revealed that no direct coupling of acoustic field with the chemical species on molecular level is the basis of sonochemistry. Instead, it arises from the acoustic cavitation, including growth, formation and implosive bubble collapse in the liquid.

Laboratory sonicators are used for the formation of nano particles as well, like nanocrystals, nanoemulsions, wax emulsions and liposomes, and for purification of waste water purification, extraction of plant oil, degassing, extraction of anthocyanins and antioxidants, crude oil desulphurization, production of biofuels, adhesive thinning, epoxy processing and a number of processes.

Laboratory Incubators

The laboratory incubators, also called microbiological incubators are applied in research and industry in a broad range of uses with living organisms. Micro-organisms and cell cultures must be incubated in a strictly controlled settings. In the standard laboratory incubator, the temperature is controlled to that extent, moreover in CO2 incubator the carbon dioxide content is controlled along with humidity and in certain cases, the nitrogen and oxygen content are also controlled by the laboratory incubators.

Following are some of applications examples of the laboratory incubators:

  • For the growth of cell cultures
  • Reproduction of the germ colonies with the subsequent count in food industry
  • Reproduction of the germ colonies and subsequent calculation of biochemical oxygen demand (also called wastewater monitoring)
  • Micro-organism reproduction like fungi, yeast, bacteria or viruses
  • Insect breeding and eggs hatching in zoology
  • Sample storage in a controlled atmosphere
  • Growth of protein crystals and others

The requirements to be fulfilled for incubators

The first and foremost requirement is temperature stability and homogeneity. Living organisms usually react quite sensitively as per changes in temperature. In order to make sure reproducible test outcomes, the temperature stability and homogeneity are critical quality criteria for the incubator, even with no operation of a fan. The nutritional media on which the cultures are produced must not be dried out under any situation, or else there is a danger that test outcomes would be corrupted or the cultures would die out completely. Appliances having natural convection are thus optimal, since the process of drying is not accelerates, as opposed to appliances having forced circulation of air.

Preventing contamination

Hygiene is the biggest priority while working in laboratory incubators where germs might enter the samples via air flow in the chamber and impurities on its surfaces. Therefore, the chambers must be developed smooth with o sharp fittings or corners.

Laboratory Furniture

Laboratory furniture is quite different from the usual definition of furniture people have in mind. There are no big sofas, chairs, tables and other common furniture items. Instead, the laboratory furniture is mainly based on special lab equipment and tools since laboratory is used for carrying out specific experiments and other sensitive measurements. In order to have accurate results of the reactions or processes being carried out in laboratory, it is important that you maintain each of lab equipment accurately so as to avoid any dust accumulation or particles deposition over it that can affect the results. In this article, we will discuss one of the vital laboratory furniture items, microscope, and the way it should be maintained.

Cleaning of lens:

The most important component of microscope is lens. Most of the manufacturers suggest its cleaning with small amount of alcohol or isopropyl or ethyl, and then it can be gently wiped in one direction. However, keep it in mind that never apply this directly onto lens. Immersion oil must be applied and wiped from the surface immediately as soon as you apply alcohol. You can use xylene to wipe oil properly. Xylene may leave a film on surface. In order to prevent it, always moisten your second wipe with alcohol and apply this to remove residual xylene.

Replacement of Lamp:

When replacing bulbs or lamps, avoid touching their glass with your bare hands. Fingerprints of your fingers left on the bulb would actually burn into the glass and decrease bulb’s life expectancy and quality.

Fitness of the microscope:

It is a nice idea, every week, for the scope user to put the focusing process through its paces. During usual use the process is probably not worked through its complete range of motion. Rotate both coarse and fine focus knobs from end-stop to end-stop several times.

Evaporative Cooling Pads: Designs

Evaporative Cooling pads

In our last post, we discussed about what evaporative cooling pads are, how they function and their application purposes in various industries. In this article, we will discuss the overall design of this mechanism and the way the cooling pads work.

Most of the designs take benefit of the fact that water has one of the largest known enthalpy of vaporization (also called latent heat of vaporization) values of any general substance. Due to this reason, evaporative coolers use simply a fraction of the energy of vapor-compression or an absorption air conditioning systems. Unluckily, except in very arid climates, the single-stage (direct) cooler can upsurge relative humidity (RH) to a level that makes the occupants uncomfortable. Two-stage and indirect evaporative cooling pads keep the RH lower.

Direct evaporative cooling (that is called open circuit) is used to decrease the temperature and boost the humidity of air by utilizing latent heat of evaporation, transforming liquid water to water vapor. In this course, the energy in the air does not change. Warm dry air is transformed to cool moist air. The heat of the outdoor air is used to evaporate water. The RH increases to 70 to 90% which decreases the cooling effect of human perspiration. The moist air has to be repeatedly released to external atmosphere or else the air becomes drenched and evaporation stops.

Passive direct evaporative cooling may happen anywhere that the evaporative cooled water can make a space chilled without the support of a fan. This can be accomplished through application of fountains or more architectural designs like the evaporative downdraft cooling tower, also termed as a “passive cooling tower”. The passive cooling tower design enables outside air to flow in through the top of a tower that is constructed within or adjacent to the building.

Laboratory Calorimeters in the Markets

Chemistry science, Laboratory glassware background

Laboratory calorimeters have become an integral part of the labs of a number of industries, especially chemical, pharmaceutical, and manufacturing, construction and agriculture. In few of our previous posts, we have discussed about what laboratory calorimeters are and how they work. In this post, we would be exploring their advanced types as developed by manufacturers today to cater their growing tests and experiments needs in terms of accuracy and outcomes.

Adiabaic Calorimeters

An adiabatic calorimeter is the calorimeter that is used for examining the runway reaction. It is heavily used in different industries. Since the calorimeter functions in an adiabatic setting, any heat produced by the material sample in test results in sample to increase in temperature and thus accelerating the reaction.
Adiabaic calorimeter is not completely adiabatic, and some heat is wasted by the sample to the sample holder. A mathematical correction factor called the phi-factor, can be utilized for adjusting the calorimeter outcome to count for the heat losses. The phi-factor is the ratio of the thermal masse of the sample and sample holder to the thermal mass of the sample only.

Reaction calorimeters

The reaction calorimeter is the one in which chemical reaction is started in a closed insulated container. Reaction heats are gauged and the total heat is got by integrating the heat flow versus time. This is the standard executed in industry for measuring heats because industrial processes are also engineered to run at constant temperatures. Reaction calorimeters are also used for determining maximum heat release rate for the chemical process engineering and for tracking the global kinetics of the reactions.

Power compensation calorimeter

Power compensation calorimeter uses the heat put in the vessel for maintaining a constant temperature. The energy given to the heater can be different as reactions need and the calorimetry signal is completely obtained from this electrical power.
Keep in your mind that all these calorimeters that have been discussed in this post are for industrial and commercial purposes and designed for large scale experiments and tests.

Evaporating Cooling Pads

 

Used Air filter details.In view of the extreme temperatures going on in the world, scientific requirements and increasingly comprehensive nature of industrial applications, the evaporating cooling pads were developed for aiding various industrial processes and facilitating the temperature control mechanisms of both households and commercial units. In this article, we would be discussing the evaporating cooling pads functions and their applications in different industries.

In order to understand the evaporating cooling pads functions and features, you must have an idea of the underlying principle in terms of its functionality. As the water is evaporated, the energy is lost from the air, which decreases the temperature. Two kinds of temperatures bear significance when it comes to evaporating cooling system of the cooling pads.

  • Dry Bulb temperature

This is the temperature which we normally think of as air temperature, gauged by the regular thermometer, exposed to the air flow.

  • Wet Bulb temperature

This is the least temperature that can be attained just by the water evaporation.

When taking into consideration the water evaporation into the air, the wet bulb temperature, as relative to the air’s dry bulb temperature is the measure of the tendency for evaporating cooling. The wet and dry bulb temperature can also be used for calculating the comparative humidity. Evaporation would occur when the humidity goes beyond 100 percent and the air starts to absorb water. Any of the given air volumes can sustain the specific amount of water vapors and the extent of the absorption would be based on the quantity it is already entailing. The humidity means how much water is present already in the air, relative to the one that the air is currently holding.

Evaporative cooling pads are heavily being used in construction, HVAC, electronics and IT industry along with the household applications for cooling down the temperature of the interiors.

Laboratory Incubators

There are a number of laboratory equipment that are very important for a number of applications, tests and experiments. Among such lab tools, are the laboratory incubators. Incubators are essential equipment for the laboratories that conduct issue and cell culture work. These protect the cells from the changes in humidity, temperature, CO2 and O2. Temperature is usually regulated via air jackets or water. Constant humidity is also maintained by the humidity water fans and troughs that are enabled with O2 circulation.

The standards and modular CO2 incubators are regulated with the IR sensors or thermal conductivity. Incubation can also be linked with hybridization in the hybridization oven or blending in water baths and incubator shakers. Important qualities to take into consideration while buying an incubator include the prevention of evaporation of media and sample desiccation, prevention of the contamination and simple way of decontamination, variable oxygen control, efficiency, humidity, CO2 control and temperature.

Whenever someone opens the incubator door, the interior temperature of the equipment is disrupted. Currents of both cool and warm air flow around interior, and the temperature control system if the incubator need to function to return the temperature inside to the set degree. Water jackets are one kind of the process that keeps incubators less prone to changing temperatures; water jackets can also be specifically valuable in case of a power failure. Along with maintaining the accurate culture conditions for the cells, the other major issue is the prevention of the contamination of the cultures. Contaminants might be exposed when a person’s contaminated glove or hand comes into contact with the interior sides of the incubators, or when an open door makes the equipment vulnerable to the contaminants present in the air. For cleaning the interior incubator’s surfaces, most of the models make use of sterilization cycles which are run at high heat.

Tips for Proper Lab Equipment Maintenance

Proper and regular maintenance of the lab equipment is of prime importance in any lab since contamination of any kind can stop the project in its tracks or may invalidate the laboratory outcomes altogether. While the maintenance is usually one of the most costly operating expenses as far as lab budget is concerned, they are just important for an accurate operation. In this article we will explore some great tips for properly maintaining lab equipment. However, it is also important to know the role of the lab technicians as well as understanding these tips since these will be executed by technicians.

Mostly, lab technicians hold the critical responsibility of keeping the lab organized, clean and fully equipped. This can entail sanitizing equipment and surfaces and cataloging equipment before and after the use, and as disposing of the labs chemicals, specimens and bio hazardous waste in accordance with the laws and regulations applicable.

Keeping the lab organized and sterile

In order to avoid cross contamination and make sure the accurate outcomes, proper sanitation and organization of the lab supplies and equipment are critical.

Protective gear and clothing

The workplace must be sanitized and lit well. Lab technicians must always wear some protective lab coat, lab gloves, mask and goggles while handling the lab specimens. The heavy duty protective wear must be worn while working with substantially hazardous materials and chemicals or when cleaning equipment used to carry noxious stuff that may damage any body organ or part of skin of human.

Cleaning the lab glassware

The sterile, clean glassware is quite important, in particular in a medical lab setting. Contamination can lead to erroneous test results. All glassware must be completely free of any grease and other kinds of contaminants including laboratory incubators. It is also important to rinse the glassware well to avoid any clinging liquid or residue on the inner walls.
