These PYREX® 125 mL micro filtering flasks are recommended for microchemical use. The vacuum hose is attached to the flask's sidearm. A funnel is inserted into the neck of the flask through a ground joint or rubber stopper. The applied vacuum facilitates the filtration process. These flasks have permanent white enamel marking spots.
These PYREX® 50 mL micro filtering flasks are recommended for microchemical use. The vacuum hose is attached to the flask's sidearm. A funnel is inserted into the neck of the flask through a ground joint or rubber stopper. The applied vacuum facilitates the filtration process. These flasks have permanent white enamel marking spots.
These 125 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 250 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.7650-22. Reference: ASTM D-29 and D-555.
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.
