Chemistry Roundbottom Flask Stands

Chemistry Lab Roundbottom flask ring bases. SImilar to cork rings, these bases hold round bottom flasks in each size: 25 mL, 50 mL, 100 mL, 250 mL, 500 mL

NOTE: As with any roundbottom holder, the flask can tip over! It's spherical after all. To reduce the risk I coated each one with a layer of rubber cement (Elmer's) This added just enough friction that slipping/tipping is minimized. You can use other types of coatings, but rubber cement works pretty well.

Caution: Never place hot glassware on a PLA or other plastic filament as it could melt or start a fire.
