Biosafety Hoods and Cabinets

A hood in laboratories are an effective means of capturing flammable, irritant, corrosive, carcinogenic vapors, etc. to prevent personnel exposures and avoid their dissemination in the laboratory atmosphere. When the hatch is down, the cab is also a physical barrier that protects the operator from hazards such as splashes, aerosols, fires, and minor explosions.

Fume hoods are a type of ventilation system with the primary function of protecting the user against exposure to chemical vapors, gases, dust, and aerosols. They function as physical barriers between reagents and the laboratory, offering protection against inhalations, spills of hazardous substances and fire.

A typical hood has a box-shaped structure with a movable window. The experiments are carried out inside the hood that is ventilated constantly and safely, usually by means of ducts. Chemical vapors are extracted and diluted many times in the atmosphere rendering them harmless to human health. If there are environmental concerns, a treated exhaust system can be installed to remove most of the vapors from the outside air stream.

It works by maintaining negative air pressures inside the cabin and preventing any air particles from escaping to the outside. The speed at which the air enters the hood is very important to guarantee the safety of the equipment. High speeds can create turbulence that will allow the air inside to escape, but low speeds may not be enough containment.

Characteristics

Class I biosafety cabinet does not protect product from contamination because raw room air is constantly entering the work area.
As a partial containment unit, the Class I biosafety cabinet is suitable for work with low to moderate risk agents (biosafety levels 1, 2 and 3) where there is a need for containment, but not for product protection.
Unlike the conventional fume hood, the HEPA filter in the Class I biosafety cabinet protects the environment by filtering the air before it runs out.
With negative pressure, protection of personnel is possible thanks to the constant movement of air in the work area.

Advantage

1. UV lamp for sterilization.
2. Soft touch control panel, LCD screen.
3. Energy saving, high efficiency, low noise.

KALSTEIN BIOSAFETY CABINET

In Kalstein you can find the ideal Biosafety cabinet and fume hood for  your laboratory.

At Kalstein we have an excellent range of Biosafety cabinets for your laboratory. That is why we invite you to take a look at the β€œProducts” menu.

Gas extraction hoods

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

 
 

Laminar flow cabinet

Laminar flow cabinets are enclosures that use a fan to force air through a HEPA filter sweeping the work surface. The air flow can be vertical or horizontal.

Biological safety cabin

Biological safety cabinets are ventilated rooms designed to limit the risk of laboratory personnel exposed to infectious agents as much as possible.

PCR hoods

A polymerase chain reaction (PCR) workbench is a work area enclosed on three sides, which provides the space to perform DNA and RNA amplification.

What Biosecurity cabinet choose to work with COVID-19?

The biological safety cabinet represents a primary containment barrier that allows working safely with biological agents such as the virus that causes COVID-19. It is equipment designed to prevent the escape of bioaerosols from the work area and, therefore, protects people and the environment from possible exposure to these agents. There are three types, known as: class I, class II and class III.

Biosafety cabinet, class II A2 (testimony)

Biological safety cabinets are ventilated rooms designed to limit the risk of laboratory personnel exposed to infectious agents as much as possible. This is especially important considering that many of the operations carried out in a laboratory involve the formation of aerosols. The main objective of this equipment is to provide a work area that minimizes the probability that an airborne particle has to escape to the outside of the cabin and thus contaminate the operator and the area around him. In addition, some of them offer protection to the material that is handled.

When a biological safety cabinet is used by properly trained personnel aware of its limitations, it becomes a very effective containment equipment to reduce the possible escape of biological contamination. However, it is important to bear in mind that a cabin is never a substitute for a proper microbiological technique.

These cabins have two systems that prevent contamination from escaping: air barriers and filters. Air barriers are created by allowing air to flow in only one direction and at a constant speed, creating a true β€œcurtain” of air known as laminar airflow. It is, by definition, a flow with no turbulence. The purpose of the filters is to trap the particles contained in this air flow and the most commonly used are HEPA filters, which retain particles up to 0.3 microns in diameter with an efficiency of 99.97%.

There are three types, known as: class I, class II and class III.
