Biocompatibility Approvals• EPO-TEK® MED-354-T cured at 150°C for 45 minutes has been tested and is ISO 10993-5 certified (Cytotoxicity testing by MEM Elution methodology).

Sterilization Information• Epoxy performance is most influenced by surface preparation and cleanliness, overall process and handling, and finally proper curing selection. While bulk
samples of MED-354-T may resist sterilization technologies such as autoclave steam, gaseous technologies, gamma radiation as well as liquid disinfectants,
the glue joints may differ. All users need to determine the suitability of MED-354-T for their given application.
• MED-354-T was found compatible with 100 cycles of Sterrad® sterilization cycles at standard concentration.
• MED-354-T is generally regarded for resisting few cycles of ETO and gamma radiation.
