我们于1979年进行人脑瘤细胞体外培养,当时在一般无菌室中的超净工作台上操作,常有细菌污染。1980年与同济大学暖通系一起设计了ZP—1型生物洁净室,能除去空气中≥0.5u的全部浮游尘粒和细菌,制造了一种较好的洁净环境,解决了细菌污染问题。本文报告其应用情况。 We conducted human brain tumor cells in vitro culture in 1979, when in the general sterile room clean bench operation, often bacterial contamination. In 1980, the ZP-1 biological clean room was designed together with the HVAC Department of Tongji University to remove all floating dust particles and bacteria in the air ≥0.5u to create a better clean environment and solve the problem of bacterial contamination. This article reports its application.
