Advice on sterilizing transfer pipets

[Joe Nomen]

My lab uses  transfer pipets by Samco Scientific Inc.  It is made of plastic
with a ball/bulb on top.  Does anyone have any ideas on sterilization
procedures?  I tried autoclaving a few and they melted.  I also do not
have access to a machine that can gamma sterilize them.  Any suggestions
would be greatly appreciated. Thank you.
