The difference between the ultra-clean workbench and the biosafety cabinet: the operating area of the biosafety cabinet is negative pressure, which is simply called ventilation. The ultra-clean workbench is to do no direct harm to the human body of the bacterial operation experiment, belongs to the positive pressure air supply, and the wind is filtered through the filter to achieve local cleanliness.

The biosafety cabinet can protect both the samples used in the test and the workers performing the operation. The ultra-clean workbench is designed only to protect the experimental material.

The ultra-clean workbench is a local purification equipment operated by a single person, and the same as the biosafety cabinet can be used for scientific research, pharmaceutical, medical and health industries, and are all in order to provide a sterile and hygienic environment. However, there are many different places between the clean workbench and the biosafety cabinet, so the two are also very different in use.
