【技术实现步骤摘要】
洁净室沉降菌采样架
本技术涉及一种采样架,尤其涉及一种洁净室沉降菌采样架。
技术介绍
洁净室是指将一定空间范围内空气中的微粒子、有害空气、细菌等污染物排除,并将室内温度、洁净度、室内压力、气流速度与气流分布、噪音振动及照明、静电控制在某一需求范围内,而所给予特别设计的房间。亦即是不论外在之空气条件如何变化,其室内均能俱有维持原先所设定要求之洁净度、温湿度及压力等性能之特性。沉降法,即通过自然沉降原理收集在空气中的生物粒子于培养基平皿(一般多采用90mm直径硼硅酸玻璃培养皿,俗称沉降碟),经若干时间,在适宜的条件下让其繁殖到可见的菌落进行计数,以平板培养皿中的菌落数来判定洁净环境内的活微生物数,并以此来评定洁净室(区)的洁净度。这个过程中,需要使用到采样架,现有的采样架的托盘四周均有阻挡边,这样虽然能保证培养基平皿位置固定,但取放过程非常不便,并且只能适应某一种特定形状的培养皿,对于其他形状的培养皿不能保证位置固定,此外,现有采样架高度不可调节,不能随意调节取样高度。
