since the outbreak of sars in 2003, the
construction of bio-safety laboratory has made great progress and rapid development
in china. bio-safety laboratories were built in many fields, such as research
of biological virus, development of biological technology and genetic
engineering. bio-safety laboratory has its own characteristics compared with
common laboratory. among the laboratories with different bio-safety levels,
bsl-3/4 is mainly used for the research and detection of highly contagious,
severe infectious disease for human and livestock, so its safety is extremely
important. if the experimental materials or laboratory space are not properly
protected, it may cause infection of laboratory personnel, or even virus
leakage, leading to a large area of virus infection and serious public
pollution safety events.
the large-scale sterilization cabinet of bio-safety
level 3 laboratory produced by mmm group of germany adopts many special
features, such as shockproof bio-safety seal, steam inlet designed at the
bottom of chamber, condensate collection and re-sterilization, on-line
sterilizable air inlet and exhaust filter device, special shape sealing ring,
etc. it can greatly reduce the possibility of infection and virus leakage.
because the samples in bsl-3/4 are highly
infectious to human and livestock, it is necessary to sterilize the core area
of laboratory and even the whole laboratory space after each experiment to
ensure that the laboratory is always on standby without pathogens. in the past,
when formaldehyde was used for sterilization, the laboratory would have
irritating smell for a long term, white crystals that are difficult to remove
and the risk of laboratory corrosion. therefore, more and more bio-safety level
3/4 laboratories (bsl-3/4) use the method of dry vaporized hydrogen peroxide
for sterilization. the vaporized hydrogen peroxide space sterilizer of pea company
in germany has the advantages of convenient movement, real-time monitoring of
sterilization environment (temperature, humidity, hydrogen peroxide
concentration), complete gasification at 150~160℃ and compliance with various laws and
regulations. it is widely used in bsl-3/4 laboratories in china and foreign
countries.
in order to reduce the times of opening the
safety door and minimize the risk of contamination of the laboratory and the
external space of the laboratory, more and more new laboratories use double door
hydrogen peroxide transfer hatch to transfer small items. pea company of
germany can provide double door hydrogen peroxide transfer hatches of various
volumes. hydrogen peroxide generator is integrated in the equipment to avoid
waste of laboratory space; the inner chamber is made of aisi 316l stainless
steel, which can resist 30% ~ 35% hydrogen peroxide solution corrosion for a
long time; german siemens controller is adopted to realize double door
interlock and authority control management.
