What To Look For When Purchasing A Benchtop Ductless Fume Hoods?


Ductless fume hoods are described by multiple names like filtered fume hoods, or carbon-filtered enclosures. Ductless Fume Hoods are self-contained and filtered laboratory enclosures that eliminates dangerous fumes, vapors as well as particles from the laboratory.

Not like conventional fume hoods, investment prices are very cheap plus no ductwork is needed. Hence, countless people think choosing one is a slam-dunk when they first discover them.

There are few crucial things to analyze before reaching the final choice to buy a ductless fume hood. Consider these aspects into careful thought to be sure that a ductless fume hood is the correct decision for the Laboratory Supplies the applications:

1. Is the common application suitable for a ductless fume hood?

Countless different classes of ductless as well as the filtered fume hoods few hoods still restrict application that can be implemented in them. Few ductless fume hoods should only be utilized light-duty instead of process explicit fume hoods. Additionally filtered fume hoods can be utilized for a broad range of chemicals, however, keep in thought that more extensive chemical amounts will ever reduce filter life. 

This indicates that:

   ·        A restricted number of complex chemicals should be applied.
   ·        No excessive heating should be taken out in the hood.
 ·  Unostentatious chemical amounts should be accepted, about 500 mls or less by chemical.
   ·        Mediocre chemical display times should be managed.

2. Will the chemicals included in the application be adequately filtered with the available carbon filters?

Typically, ductless hoods will be equipped with chemical explicit filters. Explicit filter kinds enhance chemical trapping capability for complex chemical groups; but, few chemicals cannot be securely filtered or are not filtered efficiently sufficient to enable ductless hoods to be a financially viable alternative.

3. How frequently will you have to substitute the filters?

Although you won't have the added cost of tube work downloading and wiring together with a standard fume hood you want to consider how often you want to remove your filters, and the maintenance costs associated with that, to add your total yearly filter costs.

Filter lifespans can end from a few months up to two years. You will want to search out how long the expected filter lifespan is for your application so the weigh that against the cost to establish a standard fume hood. It also considers the energy cost of running a standard fume hood which totally replaces tempered air from the laboratory and taxing the HVAC system.

4. How do the pros as well as cons of utilizing a ductless fume hood stability out for you?

If you possess decided that a ductless fume hood is most apparent suitable for the application, the ultimate thing to perform is to decide how the benefits of a ductless fume hood persist up against its disadvantages, plus how both adjust with the organization's overall purposes. 

Conclusion 

These four things are very important to look For When Purchasing a Benchtop Ductless Fume Hoods, before buying benchtop ductless fume hoods these four points will help you.

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.
