Supplier: CORNING CA

These PYREX® Kjeldahl flasks have finished necks for extra strength and uniform rubber stopper 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.
