20 cm Cell Scraper

Scientific plastics have gone from a dime-a-dozen in price, to having to auction off one of your kidneys for a single centrifuge tube. Stick it to the "man" and save some of your precious lab bucks, by printing your own cell scrapers. This design has an angled scraper for working in flasks, and a horizontal scraper on the other end for working in dishes. Simply print in PLA, sanitize in 70% IPA for an hour, and dry under a UV lamp.
