These PYREX® VISTA™ 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 blue enamel marking spots. The 50 mL filtering flask is designed to ASTM E-1406 Type 2.

These sterile disposable 10 mL PYREX® serological pipets are designed for the larger-volume user. They are calibrated (TD) with blow-out and are packed to permit easy access to several pipets at a time without contaminating the entire case. Similar to No. 7077, except multi-packed in plastic bags. New I.S.O. color-coding is printed directly on the tear strip for easy identification by size. Reference: ASTM E-714.

These sterile disposable 2 mL PYREX® serological pipets are designed for the larger-volume user. They are calibrated (TD) with blow-out and are packed to permit easy access to several pipets at a time without contaminating the entire case.

These reusable 5 mL PYREX® serological pipets are designed for cotton plugging. The uniform top-end openings permit performing of plugs and allow precise control of liquid column. Color-coded by size for easy identification and sorting. Colored graduations are enameled onto the glass. The two rings indicate the pipet is calibrated (TD) its total capacity when the last drop is blown out. Reference: ASTM E-1044.

These 10 mL PYREX® volumetric pipets were designed primarily for schools and laboratories where the Class A tolerance of No. 7100 is not required. They are constructed to the same wall thickness and length as our No. 7100, but have larger tip openings for faster delivery. It is primarily due to this faster delivery that accuracy tolerances are twice those specified for Class A volumetric ware. Reference: ASTM E-969.

These 3 mL PYREX® volumetric pipets were designed primarily for schools and laboratories where the Class A tolerance of No. 7100 is not required. They are constructed to the same wall thickness and length as our No. 7100, but have larger tip openings for faster delivery. It is primarily due to this faster delivery that accuracy tolerances are twice those specified for Class A volumetric ware. Reference: ASTM E-969.

Viva columns are based on a wide pore material we designed for optimal large-molecule separations.In developing Viva silica, we found that although many commercial wide-pore silicas meet the standard 300 Å mean pore size, most have very broad distributions about this mean, with a significant portion of their pore volume falling below 150 Å.This means a large portion of the surface area is unavailable to larger molecules. Viva…
