摘要:
JWL-6型六级微生物采样器
 JWL–6型六极撞击式空气微生物采样器采用惯性撞击原理而将悬浮在空气中的微生物粒子分级地收集到采样介质表面上,然后供培养及微生物学分析。本仪器具有采集效率高,采样时间短,捕获范围全的优点。广泛应用于医疗卫生、食品、制药、洁净室、车间、医院、室内环境等空气微生物的采样研究。
JWL-6 Six-stageMicrobial Air Sampler
TheJWL-6 was developed on the inertial impaction principle with stagedcollection apertures through which microbes are driven onto thesurface of pre-poured media contact plate for incubation andanalysis. Features high collecting efficiency, short collectingtime and wide capture range, it is ideal for health, clean room,food industry, pharmaceutical, workshop, hospital and indoorenvironment applications.
