We wanted to re-use a PETG erlenmeyer flask in our lab and we need to find ways to sterilize it using methods that doesn't involve heat because PETG melts at 70 degrees C. What could be other ways that I can use to sterilize these bottles because it would be such a waste if these bottles are only single-use?
Here are some considerations:
1. Optimal for cell culture
2. Doesnt leave residue
3. Safe
4. Compatible with PETG

Try gas sterilzation (for example ozone or ethylene oxide)
Try radiation with gamma radiation
or use UV-c
