• Autoclaving (121°C, 15 psig for 20 minutes) Clean and rinse item with distilled water before autoclaving. Certain chemicals which have no appreciable effect on resins at room temperature may cause deterioration at autoclaving temperatures. ALWAYS COMPLETELY DISENGAGE THREADS BEFORE AUTOCLAVING.
• Gas - Ethylane oxide, formaldehyde.
• Dry Heat - 106.°C for 120 minutes.
Disinfection - Benzalkonium chloride,Formalin,Ethanol,etc.
Radiation - gamma irradiated at 2.5 Mard with unstabilized plastic.
+ Sterilizing reduces mechanical strength. Do not use PC vessels for vacuum application if they have been autoclaved.

E = Excelent - 30 days of constant exposure cause no damage. Plastics may even tolarate for years.
G = Good - Little or no damage after 30 days of constant exposure to the reagent.
F = Fair - Some effect after 7 days of constant exposure to the regant like crazing, cacking, loss of strength or discoloration.
N = Not Recommended - Not for continuous use. Immediate damage may occur.
