产品简介
详细介绍
这些塑料袋是专为快速测试和处置样品而设计的，此种实验样品不必保留。通常实验样品均质，测试，然后被丢弃。该袋材料为重型聚乙烯，经过严格的消毒灭菌。
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.
