PYREX® 300 mL Round Bottom Kjeldahl Flask with Long Neck

Quality Certificate

These 300 mL PYREX® Kjeldahl flasks have tooled finished necks for extra strength and uniform rubber stopper (No. 5) fit. Wall thickness is controlled to offer the optimum balance between thermal shock and chemical resistance. They can be used in ASTM E-258 procedures. Care must be taken to ensure the bottoms of the flasks do not come in contact with the heating elements. Most Kjeldahl equipment manufacturers have ring supports for this purpose. Reference: ASTM E-1377.

One or more facilities manufacturing this product is 100% covered by renewable energy through the purchase of unbundled energy attribute certificates (EACs).
