Ultra-clean worktable (clean worktable) is designed to meet the requirements of modern industry, photoelectric industry, biopharmaceutical industry, scientific research and experiment on the cleanliness of local working areas.

Ultra-clean workbench (clean workbench) is different from biosafety cabinet (biosafety cabinet).

The ultra-clean workbench can only protect the reagents operated in the workbench from contamination, but cannot protect the staff; The biosafety cabinet is a negative pressure system, which can effectively protect workers.

The working principle of the ultra-clean worktable is that the air is sucked into the prefilter through the fan, and then filtered by the high-efficiency filter through the static pressure box. The filtered air is sent out in the state of vertical or horizontal air flow, so that the operating area can reach the level of 100 cleanliness and ensure the production requirements for environmental cleanliness.

The ultra-clean workbench can be divided into vertical flow ultra-clean workbench and horizontal flow ultra-clean workbench according to the airflow direction.

The ultra-clean workbench can be divided into unilateral operation and bilateral operation according to the operation structure, and can be divided into ordinary ultra-clean workbench and biological (medical) ultra-clean workbench according to the purpose.

Ultra-clean worktable is a purification worktable used in medical and health, pharmaceutical, chemical experiments and other fields, providing a sterile, dust-free and clean environment.

When it comes to the ultra-clean worktable, some people will ask whether it is the same as the biosafety cabinet?

In fact, the ultra-clean worktable is sterile, dust-free and clean, which can protect the reagents operated in the worktable from contamination.

The biosafety cabinet is designed to protect the operator, laboratory environment and experimental materials from being exposed to infectious aerosols and splashes, which may be generated during the operation of infectious experimental materials such as primary culture, bacterial strains and diagnostic samples. Outstanding safety and effective protection of staff.

The main differences between the ultra-clean workbench and the biosafety cabinet are as follows:

1. Biosafety cabinet is a kind of safety equipment widely used in scientific research, teaching, clinical inspection and production in microbiology, biomedicine, gene recombination, animal experiment, biological products and other fields. It is also the most basic safety protection equipment in the laboratory biosafety primary protective barrier.

2. The ultra-clean worktable is designed to protect the experimental materials. The air is sucked into the prefilter through the fan, and enters the high-efficiency filter through the static pressure box for filtration. The filtered air is sent out in the vertical or horizontal airflow state, so that the operating area can reach the level of 100 cleanliness and ensure the production requirements for environmental cleanliness. Only samples can be protected, not operators.

3. The biosafety cabinet is a negative pressure purification workbench. When the biosafety cabinet is operated correctly, it can completely protect the staff and test samples, and prevent cross contamination. The ultra-clean workbench is only a clean workbench, which protects the operating objects rather than the staff and laboratory environment.

Therefore, in the scientific research, teaching, clinical test and production of microbiology and biomedicine, biosafety cabinets should be used instead of ultra-clean worktables.

4. In terms of cleanliness, the biosafety cabinet is also better than the ultra-clean workbench.
