Polypropylene (PP) and polypropylene copolymer (PPCO) products can be autoclaved many times. We have PP containers in our lab that have been autoclaved over 100 times and, although they have yellowed somewhat, they are still in service.
-Fluoropolymer products, i.e., products made of Teflon PFA, FEP or ETFE, can all be autoclaved without problems, except for the stopcocks in NALGENE ®
Separatory Funnels, which should not be autoclaved because of resultant leakage problems.
-Polycarbonate (PC) products can be autoclaved with caution; they should not be exposed to alkaline detergents or steam additives, and they may withstand only up to 30-50 autoclaving cycles, depending on the use
-When autoclaving NALGENE bottles and carboys, be sure to completely disengage the closure from the bottle threads OR use a carboy vent. This is necessary because the leakproof NALGENE sealing system does not allow venting, which can cause these containers to collapse during the exhaust cycle.
