Biocompatibility Approvals• EPO-TEK® MED-301-2FL cured at 60°C for 4 hours 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-301-2FL 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-301-2FL for their given application.
• Gamma Radiation/ion beam will discolor MED-301-2FL, thus altering its appearance.
See Technical Tip # 29: Gamma Sterilization for Medical Devices and its Effect on Epoxies for more information.
http://www.epotek.com/site/files/Techtips/pdfs/techtips_29.pdf• MED-301-2FL is generally regarded for resisting few cycles of ETO and gamma radiation.

Packaging Availability• EPO-TEK® MED-301-2FL is available in specialty packaging such as Pre-Mixed Frozen Syringes (PMF), or bulk (A & B containers).
