[DIYbio] Re: Cleaning methods for pipette tips

sonicating in Alconox soapy water will remove almost everything biologic that might contaminate your next sample. Then rinse. This is our preferred way to reuse most of the plastics in the lab.

also, pipette tips DO survive autoclaving, so after rinsing off the alconox with distilled water you can autoclave them in their box.

Many pipette companies will send you free samples of their tips in an autoclavable box, just ask them! If you are going to reuse tips then that one sample box should last you a good long time.
