Durable, break-resistant polypropylene jars are autoclavable

Before autoclaving, set closure on top of the container without engaging the threads.

The 70mm necks accommodate fixtures or closures with mason jar threads. Fit Osterizer® blending assemblies. Also handy for fluid transfer in the lab or field when used with the filling/venting closure. Leakproof, white, polypropylene screw closure system includes neck ring for shrink seal.
