氣溶膠采樣器是一種高效的玻璃制收集裝置，與大流量負(fù)壓泵配合使用，將生物氣溶膠收集到液體中保持很大限度的生物活性 ，也可捕獲空氣中的微生物進(jìn)行分析。

氣溶膠采樣器的內(nèi)部，采用了專業(yè)性設(shè)計(jì)以便減少顆粒反彈來保持生物活性。

產(chǎn)品特點(diǎn)：

· 適用于空氣傳播的細(xì)菌、真菌、花粉、病毒、內(nèi)毒素、真菌毒素和其它碎片

· 用優(yōu)質(zhì)玻璃制成-可高壓滅菌，可重復(fù)使用

· 克服了撞擊式采樣器采樣問題

· 三個切向噴嘴以特定角度噴射粒子到內(nèi)壁，從而減少了顆粒反彈并保持了微生物的完整性

· 旋旋流液體收集方法很大程度上減少再氣溶膠化，溫和地夾帶生物氣溶膠，以保持生物活性

· 可使用粘度高于水的非揮發(fā)收集液，例如：ViaTrap®礦物油等

· 與 ViaTrap® 礦物油一起使用時(shí)，采集效率在 8 小時(shí)的采樣期內(nèi)保持恒定

· 采集的樣品適用生長培養(yǎng)、顯微鏡計(jì)數(shù)、生化分析、免疫分析、聚合酶鏈反應(yīng)（PCR）等
