PYREX® Ostwald-Folin Class A Reusable Glass Pipets
Manufacturer: Corning
These precision PYREX® blood chemistry pipets meet or exceed specifications for Class A volumetric ware as indicated by ASTM E-969. Shorter, and more compact than a Class A volumetric pipet, these pipets were originally suggested by Folin for use in determining total nitrogen, urea and ammonia in urine; they are now generally used for blood serum tests. They are calibrated "to deliver" (TD) by blowing out the last drop. Colored graduations are enameled onto the glass.
