產品簡介
詳細介紹
這些塑料袋是專為快速測試和處置樣品而設計的，此種實驗樣品不必保留。通常實驗樣品均質，測試，然后被丟棄。該袋材料為重型聚乙烯，經過嚴格的消毒滅菌。
When the sample does not have to be retained, these bags are designed for quick testing and disposal. These bags have a perimeter seal, are made of the same film as Whirl-Pak® bags, and are sealed at the top. There is a perforation to protect sterility and allows for separate handling of each bag. These are Whirl-Pak® quality without the wire-closing tab.
