Laboratories are facilities where scientists and medical experts conduct research and other tasks related to their disciplines. Because labs frequently feature specialized equipment to assist with such work, you should be familiar with the most common laboratory gear and their purposes. For a variety of reasons, some of the most popular types of laboratory equipment can magnify, measure, ignite, weigh, or retain various chemicals.
It is essential for any aspiring medical students to know and understand the lab equipments which they will have to use in a daily basis. One of the many that will be introduced today is the biosafety cabinets. It is one of the most common equipments you can find in any research laboratories. Even manufacturers of biosafety cabinets in Malaysia have to adhere to the proper rules, regulations and policy when manufacturing this equipment. Here is a brief introduction on what entitles biosafety cabinet, its uses and importance.
What is it?
A biosafety cabinet (BSC) is a confined, ventilated scientific workstation for securely processing with materials infected with (or suspected to be infected with) pathogens that need a set biosafety level. A HEPA filter cleanses the constant airflow before it is released into the environment. There are several distinct types of biosecurity systems, each with its own level of experimental procedure. In 1950, BSC were first approved for sale.
The primary function of a BSC is to provide pathogen protection for laboratory workers and the general environment. As it departs the biosafety cabinet, all vapours are HEPA-filtered, eradicating dangerous germs and viruses. When dealing with biological agents, Biological Safety Cabinets are divided into three categories based on their containment abilities.
Cabinets of Class 1
Protects both the operator and the surroundings. When interacting with biological agents that provide a low to moderate danger, this device is used.
Levels of biosafety: 1, 2, and 3
Cabinets of Class 2
Protects operators, the surroundings, and the material. When interacting with biological agents that provide a low to moderate danger, this device is used.
Levels of Biosafety: 1, 2, and 3
Cabinets of Class 3
A “glovebox” for highly specialized laboratory work. A Class 3 cabinet has the same degree of protection as a Class 2, but it is built for dealing with Biosafety Level 4 extremely contagious agents and offers the best coverage for the surroundings, material, and operator.
When interacting with biological agents that pose a very high danger, this device is used.
4th level of biosafety
All in all, the above explanation is just a brief introduction to biosafety cabinets. If you are interested in the different levels of biosafety, you can check this website. Again, there are many other lab equipments that you should know about and get yourself familiar with. Some lab equipments are easy to handle and have a straightforward purpose, but others have a much more specific purpose to them. Knowing well the purpose and how to use them is important as to avoid any unwanted incident in the future.
