This is off topic but not having been in a chemistry since high school (50 years ago!) I did not know these single channel pipettes existed. When I watched a video on using it correctly the clinician disposed of the tips each time she used them. At $.30 each that is a little steep for my self-funded "lab." My question may justly cause you to roll your eyes but I'll risk that and ask, if I label the tips and only use each type in specific regents can I get away with reusing them?
Also just a second note....If you rinse the tips well in RODI water and let the dry they can be reused
