Pyrex Erlenmeyer Flasks, all sizes

Pyrex® Erlenmeyer flasks are the science industry standard! Get the right size for your needs, ranging from 50 mL to 2000 mL.

These Pyrex® flasks from Corning can be heated directly in an open flame. Low coefficient of thermal expansion means this thick-walled glass Erlenmeyer flask (also known as a conical flask) withstands typical laboratory temperature variations. Use for mixing and heating. Included graduations (lines) are approximate and not intended for accurate liquid measurement.

Flask Specifications:

• Pyrex® Erlenmeyer flasks are made from highest quality borosilicate glass and meet ASTM E438 specifications
• Low coefficient of thermal expansion means this glass withstands typical laboratory temperature variations
• Marked to fill in 10-200 mL increments
• Markings are accurate to +/-5%
