Made from Pyrex borosilicate glass with uniform wall thickness. These flasks have reinforced necks, are autoclavable and have clear easy to read graduations.
If using Pyrex® conical flasks to prepare culture media or to heat viscous solutions, remember to stir the solution regularly to dissipate the heat. Failure to observe this procedure can result in thermal breakage.
Made from heavy duty Pyrex
Mechanically stronger than standard flasks
