Unique closed circuit air purging system allows air and bubbles to be eliminated from the dispenser without loss of valuable reagent. Reagent "guard valve" prevents accidental discharge of reagent when the dispenser is not in use. Leakage and the need for discharge tube caps are eliminated. Exclusive integrated swivel neck allows the discharge tube to be turned 360° for convenient dispensing. The fit of the dispenser on the bottle is not affected, even when using adapters. Incorporating a polypropylene housing, it is fully autoclavable to 250°F (121°C) for sterilization.

Schellbach Burets

Schellbach burets employ a blue line on a broader white band running vertically behind the scale to create an optical effect which causes the meniscus to assume an apparent form. This assists in avoiding parallax mistakes.
