Amber Class A Automatic Zero Schellbach Burette with 1000mL Reservoir, 25mL, 29/32 Joint, Borosilicate Glass

The Eisco Labs Automatic Zero Burette features a 25mL amber Class A burette mounted on a 1000mL reservoir with an integrated automatic zero facility. Class A accuracy per ISO 385 is delivered through 0.10mL subdivisions, ±0.05mL tolerance, and a 29/32 ground joint. A vertical Schellbach white stripe with central blue ribbon makes the meniscus easy to read precisely, and an intermediate PTFE stopcock allows complete drainage of excess liquid back into the reservoir. Both the burette and reservoir are made of precision-bore borosilicate 3.3 glass for durability and chemical resistance, and feature chemical-resistant blue printing. Each unit is individually calibrated to deliver (TD) and ships in custom foam packaging for safe transport and storage.
