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.

Class ISO 5 horizontal laminar flow cabinets (former class 100) are ideal for jobs where it is necessary to ensure the products are protected from external contamination and cross-contamination. Thanks to the specific way the side walls, located inside the inner perimeter of the filter, are assembled it is possible to prevent any contaminants that may be present from entering the work area through the filter frame thanks to th…

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…
