Flow Hoods and Laboratory Biosafety Cabinets

Laminar flow hoods are those tools that allow a sterile and safe area to be obtained for any need that is required within a laboratory. They can be: Horizontal and Vertical. It basically constitutes a space, which, by means of a specific treatment of the air, allows to work in an area with a strict control of non-road particles.

This type of equipment is used for certain processes where extreme contamination control is needed. Normally, these systems are used for microbiological control procedures, packaging process, sterile filling, etc. but in no way should they be used for processes involving strains of contaminating biological agents, whether these are known or not.

For these cases there are biological safety cabinets, prepared for the protection of the product / process, the operator and the environment.

Laboratory hoods: Differences

Laboratory hoods are fundamental pieces in the operation of this space to maintain air quality. The variety of hoods in the industry responds to the needs of scientists. Laminar flow hoods, biological safety hoods, and fume hoods all serve a purpose.

These are forced circulation cameras that, depending on their specifications and design, provide different levels of protection.

They are essential in a clinical microbiology laboratory and are classified according to the level and type of protection. In principle, it is necessary to distinguish the differences between fume hoods, laminar flow cabinets, PCR cabinets and biological safety cabinets.

The fume hood (or fume hood) is a ventilated enclosure that captures fumes and vapors from the handling of chemical products in the laboratory. 

Our best selling Hood:

The fume hood is used to protect the laboratory environment and the operator during general chemical applications. It actively protects the operator from inhaling toxic fumes and drastically reduces the risk of fire and explosion. By installing a suitable filter, you can also protect the environment. Advantages:

UV lamp for sterilization.
Resistant to weak acids and alkalis.
Adjustable air speed: 9 levels
Motorized front window, adjustable in height.

Care and maintenance to be considered

Each model that we, KALSTEIN, as a Laboratory Equipment company, offers you, has different settings, parts and characteristics that range from the concept of different refrigeration and freezing temperatures to design, you can see it through our online purchase channels


Of course, in some cases, laboratory equipment needs to be replaced entirely, especially when it breaks or breaks completely.


Restoration refers to the process of disassembling parts of laboratory equipment and cleaning or replacing each component completely.

Calibration services

Calibration services should be sought regularly. These preventive and detailed services will increase the accuracy of the equipment

 Regular cleaning

Despite being relevant, regular cleaning is often overlooked by scientists. If the laboratory equipment is not clean as it should be


The maintenance, as well as the repair of the laboratory equipment must be carried out by a qualified technician or professional.

How does an extraction hood work?

A fume hood or cabinet in laboratories is an effective means of capturing flammable, irritating, corrosive, carcinogenic, etc. vapors. to prevent personal exposures and avoid their dissemination in the laboratory atmosphere. When the gate is down, the cab is also a physical barrier that protects the operator from hazards such as splashes, sprays, fires and minor explosions.
