Biological Safety Cabinet is widely used in medical and health care, disease prevention, food hygiene, etc. Various kinds of biological experiment, etc, Biological safety cabinet is the important basis of biological safety and environmental safety. General according to the differences in the levels of safety protection of bio-safety cabinets, biological safety cabinet can be divided into three types such as primary, secondary and tertiary, level 1 is few now, currently the most widely used secondary biological safety cabinets, high class is generally used in safety laboratory.

200 yuan “sea cucumber†has no mouth last week, the public Zhang and company colleagues bought some boxed water and sent sea cucumbers with a “privileged price†of about 200 yuan. “Each box of 10 was quite large, and I thought I had lost one.
