Durable, break-resistant polypropylene jars are autoclavable. 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.
Before autoclaving, set closure on top of the container without engaging the threads.
