Burettes With Straight Bore PTFE Key Stopcock, Class A, Model No.: KI- 114

When you use a burette you expect accuracy, reliability and durability. Only KISIL brand burettes offer all three even after repeated usage. A combination of the best material and workmanship goes into KISIL brand burettes. The highest quality accurate-bore tubing is selected to provide uniform and accurate graduations. Each burette is individually calibrated for precision and high accuracy. All graduations are in durable white enamel. The burette stopcocks are specially ground so that they provide a leak proof operation. It is advantageous to use different types of greases depending on the reagents used to get leak proof operations. Stop-cock plugs are solid pressed and ground. These are not interchangeable.
