Biological Safety Cabinets
Biological
Safety Cabinets is very useful for offering the protection from microbiological
contamination in the lab environment, including both operators as well as
product protection.
For
Which Purpose Biological Safety Cabinets Are Used?
Biological Safety Cabinets are used
for a
broad range of scientific, research as well as development companies within
both the commercial along with non-commercial industries, such as medical,
pharmaceutical, clinical research, education, defence, as well as general
healthcare sectors. Biological Safety Cabinets safeguard materials, users as
well as the environment from aerosol hazards and other types of environmental
contamination.
Product
protection needs while the experiments carried out within the laboratory are
prevented from hazardous toxins as well as impurities. Environmental
protection is the most important use of a protection cabinet as it
involves the security of the complete workplace in which the person operates,
as well as the methods, take place. Cleaning up the workplace environment is a
pre-requisite to perform the other two protection functions.
They
defend the user as well as the environment from aerosols occurring from the
handling of potentially hazardous as well as dangerous micro-organisms, with
air discharged to the atmosphere being filtered.
The
internal design, the airflow aerodynamics as well as monitoring, the built-in
protection devices as well as the precise manufacturing, guarantees the
uppermost performances at the most stringent safety levels. Besides protection
of user as well as sample material, the human design factors (ergonomics) of
the work become more and more significant.
A
biological safety cabinet is often referred to by other names such as biohood,
tissue culture hood, or biological fume hood. Entire biological safety cabinets
have at least one High-Efficiency Particulate Air (HEPA) filter. These cabinets
operate with a laminar airflow (example the air flows with uniform velocity, in
one direction, along parallel flow lines).
There are three classes of safety cabinets.
When
selecting a biological safety cabinet, classification is a significant factor
to consider. The standards of each type of cabinet are dissimilar depending on
the sort of purpose that each one can perform. BSCs are classified into three
types by a US-based organization known as the Center for Disease Control as
well as Prevention.
Biosafety
cabinets are classified into three classes: I, II and III.
Class I offers protection for the user as well as the neighbouring environment,
however no protection for the sample being manipulated. Class II provides
protection for the user, environment as well as sample, and is divided into four
types: A1, A2, B1 as well as B2. The main differences are their smallest inflow
velocities as well as exhaust systems. Class III, also known as glove boxes,
provides maximum protection; the enclosure is gas-tight, as well as complete
materials enter and leave through a dunk tank or double-door autoclave. Choice
of the cabinet, therefore, depends on the level of protection required for the
laboratory worker and the sample of interest.
