PLAS transfer PPTtes are molded into one-piece units from low density polyethylene. They eliminate cross-contamination encountered with rubber bulbs and reduce exposure when working with hazardous or infectious samples. Ideal for all laboratory procedures that require fast and safe transferring of liquids. PPTtes can also be used as freeze VLS or as STOR and transport containers by merely heat sealing the TPS closed after filling. They can be sterilized if required by gas or radiation. PPTtes are supplied non-S.
