The difference between the biological safety cabinet and the clean workbench 1 The biological safety cabinet is generally used to do pathogenic bacteria, mold yeast, the operating area is negative pressure, simply said to be exhausting the air everywhere, of course, the pathogenic bacteria are not directly extracted and discharged to the outdoor, it is filtered on the top leaker of the biological safety cabinet, and the exhaust air volume can be divided into 50% external discharge type, 75% and 100% external discharge type
.
2 The clean table is to do the operation experiment of conventional bacteria that generally do not have direct harm to the human body, and the positive pressure air supply, the wind blowing to the sample and the experimenter is filtered through the filter to achieve the local hundred level
.
3 The clean bench is equivalent to a reduced sterile room (sterile space
).
Simply put, the biological safety cabinet is to suck air into it, to prevent biological germs or reagents from spilling out of the safety cabinet to contaminate laboratories and experimenters, is to protect people design
.
The clean bench is an instrument that blows air outward and is an instrument
that meets the sterile environment of the test bench.
