Micrewtube® With Lip Seal and Flat Screw Cap

This series of tubes is available either plain or with printed graduations and white marking area for sample identification. Lip seal screw caps are unattached but incorporate a flat top which provides a writing surface. These flat surfaced tubes can also be used with automatic capping machines and in packaging industries. Closures are supplied in natural color.

Tubes are made of polypropylene while polyethylene caps are easy to screw on and off. More economical than T335 Series O-ring seal model. Cannot be autoclaved since closure is made of high density polyethylene. Non skirted tubes can be centrifuged up to 20,000g. Will withstand temperatures from -196 ° C to +110 ° C.
