What is the use of Benchtop Ductless Fume Hoods and Horizontal flow ISO 5 clean bench?


The benchtop ductless fume hoods are also commonly referred to as the recirculating fume hoods. These are portable and ductless enclosures where the folding sash helps in removing different types of hazardous fumes, toxic vapors and other particles from the lab environment.

The air gets directed towards the filter chamber. This chamber houses different types of filter media like HEPA and Carbon and this is dependent on the exact type of the particulate matter or vapor which gets generated. The different combinations of filtrations are available like two types in carbon filters, one type of HEPA filter and a combination of HEPA and carbon filter.

You will be able to use the standard carbon filters in order to chemically remove the organic vapors by adsorption process. The acid gases, ammonia are specifically targeted in carbon filters. HEPA filters provide 99 percent efficiency in removing particulate matters and are useful with chemical powders and other particulates.

The prime advantage of the Benchtop Ductless Fume Hoods is that they come with a very cheap installation process as there is no special ductwork required and wall penetration can also be ignored. Also another main benefit is that the ductless exhaust hoods are portable and hence they are easily moved from one location to the other within the lab.

Horizontal flow hoods:


The horizontal flow hoods are a part of the laminar flow system. It is also a crucial concept that helps in the control of particulate contamination. The laminar airflow is basically defined as the air which is moving at a constant speed in a constant direction. The air removes all particulate and toxic material and helps to keep the lab environment free from toxicity. The horizontal benchtop flow hoods are also portable and have a simple design. This design ensures that the cleanest areas are the ones nearer to the face of the filter.

In laminar flow hoods there is the question about the direction in which the air should be moving. In the horizontal laminar flow hoods the air flow is from the filtered position which is behind your work surface. You will need to choose a laminar flow hood depending upon several issues like the specific requirements for the clean environment, the location of the process, the design of your work surface; the operator’s safety issues should also be addressed.

The advantages of these benchtop flow hoods:

1.      They will reduce a lower the turbulence from the air striking your work surface.
2.      There is no sash and hence it will be relatively easier for working and positioning your equipment. But you need to be careful as the air will blow directly towards the face of the operator.
3.      The hands and the gloves would not be that contaminated.

What is the important of Stainless Steel Glove Boxes and Vacuum Glove Boxes


Laboratory glove boxes which are often referred to as lab glove boxes are basically secured and sealed container boxes which have openings on their sides along with two attached gloves. The openings can be either on the same side or on opposite sides. The gloves will allow the worker to be easily working inside an isolated environment. In this article, you will be learning more about the importance of stainless steel and vacuum glove boxes.

Most of a lab glove box (in certain instances the whole glove box) walls get made by clear and acrylic plastic. At times tempered glass can also be used in order to facilitate the visibility of various processes or manipulations which are taking place inside the chamber. There are two primary types of glove boxes which are mostly used in laboratories: stainless steel glove boxes and vacuum glove boxes . These help in protecting the people who are working inside the lab from getting contaminated by any type of hazardous materials and malignant bacteria. The vacuum glove boxes also help in maintaining a constant gas environment when any experiment is getting conducted.

Inside a laboratory you will find both types of glove boxes being used. It is important that one checks the exact specifications and requirements of a particular lab before deciding on the type of glove box that needs to be bought. This will ensure that the appropriate glove box is purchased and it can fit the requirements and the processes that would be performed in the lab.

Stainless Steel Glove box:



1.      These glove boxes are designed in such a way as to reduce leakage during the vacuum cycling process.
2.      The stainless steel will help in eliminating corrosion and reduce contamination.
3.      These glove boxes can support a vacuum level of upto -% Hg.
4.      It will have a right sided air lock facility.
5.      It will provide a clean, safe, air tight and air controlled environment which will be quite useful for various different manufacturing processes.
6.      The single unit will feature two ten inch diametered ports which can provide a large range in motion.
7.      The glove boxes can efficiently remove oxygen and replace it with inert gases.
8.      Specific oxygen level monitor and analysers help to keep oxygen levels to a minimum.

Vacuum Glove Box:


The vacuum glove boxes is primarily used for manipulating objects, different substances and simulates different environments where it is impossible to get a direct physical contact with the samples and test environments. The vacuum glove box can be useful for several industry like in the semiconductor, material science and so on. It is useful in any application where manual handling with material analysis would be required in an unusual environment.
