Polypropylene and Polycarbonate Erlenmeyer Flasks are Unbreakable So They're Safer than Glass
Polypropylene and Polycarbonate Erlenmeyer Flasks are long lasting and far safer than glass flasks for use in shakers. Flasks are autoclavable.
Use Polypropylene Flasks for general lab use. No. 77220 includes molded graduations on the transparent surface to make liquids and readings easily visible.
Polycarbonate Flasks stand up to preparation and storage of culture media and culturing techniques. Closures do not have liners so there is less chance of harboring contaminants.
