Laboratory 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. In addition to Burettes with glass stop-cocks we have burettes with straight bore PTFE stopcocks and a range of Boroflo Burettes fitted with Boroflo(GP) screw thread stop-cocks with PTFE Keys. Boroflo Burettes are fitted with Boroflo GP(General Purpose) Screw thread Stopcocks with PTFE keys offering the following operational advantages:
