ü  Economical

Many companies choose portable ductless fume hoods because they are extremely cost-effective solutions in comparison to larger fume hoods that require permanent installation and ventilation systems, not to mention the costs of these systems themselves.

All it takes is one spark or open flame in a room full of volatile chemicals, and all that's left are fumes and rubble. Therefore, get portable and ductless fume hoods to clear out toxic fumes from your lab to avoid accidents. These fume hoods are available in variable sizes to meet different requirements.

Why Choose Horizontal Flow Hoods for Your Lab?

 For any lab using chemical, biological or hazardous materials, it is crucial to control and contain the flow of air to prevent contaminants from escaping and entering the work area. Horizontal flow hoods are an excellent solution for these labs because they provide a barrier between workers and overhead chemical contamination.

They also offer superior filtration than conventional hoods because they are vertically aligned. Here are a few reasons why horizontal flow hoods are best for your labs:

1.      Better Control Over Contamination

Horizontal hoods offer a better barrier from airborne contaminant exposure than any vertical hood on the market. This is because the air can be filtered from the top and bottom, which filters out contaminants from above, below and both sides. Vertical hoods are only filters for contamination coming downward, leaving contaminants to enter or exit from gaps in the top of the unit.

2.      Improved Employee Safety

Horizontal flow hoods achieve greater internal filtration than vertical hoods because their design allows for greater airflow, increasing filtration ability. This also improves employee safety since they provide more overall protection than a vertical unit. You can create a safe working environment inside your lab and ensure that all toxic fumes are taken care of. Horizontal Flow Hoods have built-in pre-filters to reduce particulate and liquid contamination exposure.

3.      Better Applications

Horizontal units are better at containing hazardous materials within a lab because they filter horizontally and vertically (as opposed to only vertically). They are also better at containing hazardous materials within a lab because their design allows for multiple filter changes, eliminating the need for expensive replacement filters or parts.

4.      Longer Filter Life

Horizontal units allow for greater airflow, filtration area and efficiency than vertical units. These factors contribute to longer filter life and more consistent filtration/ventilation. In addition, the lower amount of filters in a horizontal unit (as opposed to vertical) means that they can be cleaned less frequently, thus saving both time and labour costs on the user's part.

A horizontal fume hood is designed to be reused instead of disposable, which saves you money and extends its useful life. There is no need to worry about where you place chemicals since horizontal flow hoods will simply pull them out of your work area as required.

 

What Are Gravity Convection Ovens, and Why Do You Need One?

 

Gravity convection ovens for laboratories have a unique design that works without using any blowing fan. It works on the principle of thermal expansion of hot air, which proves to be a cost-efficient alternative. They're also better at retaining heat and drying chemical compounds to yield better results in any thermal expansion.

These gravity convection ovens prove to be of great help in certain sensitive experiments, temperature control, and evaporation of chemicals. However, a brief introduction to the basics of gravity convection ovens is essential to make the best of use.

Gravity Convection Ovens For Lab                 

Gravity convection ovens work by air currents that form due to thermal expansion. The hot air rises, hit the ceiling, and then falls back down continuously, resulting in uniform heating of the material within the oven. Gravity convection ovens are designed with a separate entrance and exit to ensure that items placed within do not get burnt or damaged due to direct contact with hot air.

The working mechanism of Gravity Convection Ovens is similar to that of forced convection ovens; they differ only because they don't use any blower fan or circulating pump. Instead, the heated air inside the oven rises upwards by buoyancy while cool air flows in from the bottom, which in turn helps heat the material inside.

Why Do You Need One?

In addition to saving cost and energy, gravity convection ovens are ideal for drying chemical compounds. The air within is heated along with the material placed in them, and the convection currents lead to an even distribution of heat.

Temperature can be easily maintained at the desired level by controlling the flow of coolant from the bottom. This allows you to adjust the temperature per your required field and get optimum output. Take a look at these pointers to understand the importance of these ovens in your lab:

ü  Control Temperature

Since these ovens work without electricity, they allow easy temperature control. You can easily adjust the heat and maintain it at the desired level. In addition, the flow of coolant from the bottom can be adjusted as per requirement, which further helps to keep the temperature at an optimum level.

ü  Uniform Heating

The heating in gravity convection ovens is uniform throughout because the air currents induced are balanced and don't end up affecting a particular area within the oven, like in forced convection ovens where heated air rises. However, hot air tends to hit one side of the material placed due to a lack of airflow.

Thick glass makes up the walls of these ovens, which helps retain heat for a long duration; this proves helpful in temperature-sensitive experiments that require heating or cooling at a constant rate over a long period. For example, it can help dry different chemical compounds by evaporation.

What Is A Benchtop Shaking Incubator & How Does It Works?

 A benchtop shaking incubator is designed to help research based on hybridization, cultivation, biochemical reaction, fermentation, tissue and bacteria research, etc. The machine consists of an incubator mounted on a shaker stand with three or four air cylinders and shock absorbers. Shaking incubators are orbital, orbital shaker, rotary, or oscillating shaker incubators.

Working on a Benchtop Shaking Incubator

The incubator is kept in a stand and the machine revolves at a speed of 250 to 700 rpm. The rotating action of the shaker and the motors attached to it cause the liquid in the in-travel fluid chamber to vibrate, thereby producing an electrical field. The electrical field increases or decreases depending on whether the output liquid is positive or negative. As a result, a small amount of transfer of current generates heat in the liquid. This heat generates additional vibration that ultimately helps in increasing plant growth.

What Are Their Applications?                           

A Benchtop Shaking Incubator is mainly used for microscopy research, tissue culture, bacteriology, industrial fermentations, and more. They are also used in schools for teaching microbiology and cell research. Benchtop shakers have a sealed chamber fitted with shelves on which you can insert your test tubes and bottles into the machine.
