GR-1353型空氣微生物采樣器

1 Product Overview

青島國(guó)瑞英文版空氣微生物采樣器

GR-1353 型空氣微生物采樣器（以下簡(jiǎn)稱(chēng)采樣器）是我公司精心研制的一種專(zhuān)門(mén)用于采集空氣中微生物的采樣儀器，它基于安德森撞擊法原理，按一定流量抽取空氣，使氣流中的微生物粒子加速撞擊到含營(yíng)養(yǎng)瓊脂培養(yǎng)基的培養(yǎng)皿表面，經(jīng)培養(yǎng)形成肉眼可見(jiàn) 的菌落，對(duì)菌落進(jìn)行計(jì)數(shù)并根據(jù)采樣體積計(jì)算空氣中活個(gè)體的濃度
