These Home Science Tools Erlenmeyer flasks are made of high-quality borosilicate glass that can be heated directly in an open flame (like an alcohol lamp). Use a #6-1/2 stopper for this 250 ml glass flask. Flasks are used for mixing and heating and will withstand typical laboratory thermal variations common to chemistry processes like heating and cooling. The graduations are approximate and not intended for accurate liquid measurement.

NOTE: Actual product may vary from the one pictured due to differences in suppliers.
