These 500 mL PYREX® iodine determination flasks are blown in specially designed molds, thereby insuring uniformity and proper contour. The No. 22 Standard Taper stopper projects above the liquid seal trough to facilitate removal. For replacement stoppers, see No. 7640N. Reference: ASTM D-29 and D-555.
These 100 mL PYREX® Kjeldahl flasks have tooled finished necks for extra strength and uniform rubber stopper (No. 2) 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 support…
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 support…
These 800 mL PYREX® Kjeldahl flasks have tooled finished necks for extra strength and uniform rubber stopper (No. 7) 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 support…
These small 30 mL PYREX(r) Kjeldahl flasks, without tooled neck, is suitable for multiple microdigestions. They take a No. 0 rubber stopper. 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-147.

These 100 mL PYREX® EZ Access™ wide mouth volumetric flasks are calibrated to Class A tolerances and are designed for microchemical work. Low actinic stained glass provides protection for materials sensitive to light. The protective color is an integral part of the flask, which retains its mechanical strength, chemical stability and thermal resistance. The heavy duty, wide mouth facilitates filling and mixing. Supplied with an…
