Accuracy, reliability and durability are the essentials of a Burette. Only Borosil branded Burettes offer you these three benefits even after repeated usage, as they are made with a combination of the best material and workmanship. The highest quality accurate bore tubing is selected to provide uniform and accurate graduations. Each burette is individually calibrated on a fully automatic machine for precision and high accuracy. All graduations are marked in durable white enamel. The stopcock plugs are not interchangeable.

In addition to Burettes with glass stopcocks, Borosil offers Burettes with straight bore PTFE stopcocks and Boroflo (GP) screw thread stopcocks with PTFE keys.

Boroflo Burettes fitted with Boroflo GP (General Purpose) screw thread stopcocks with PTFE keys offer the following operational advantages:

• Lubrication is never required, ensuring no seizure and no contaminating greases.
• Excellent flow control which is important for Burettes
• All-glass / PTFE pathway, highly resistant to chemical attack
• The unique Fluon / glass seal ensures no leakage
• No springs or retaining devices makes it easy to dismantle and clean them
• Absence of ground surfaces results in low absorption of radioactivity
• Consistent performance between 0 C and 50 C

Borosil offers Class A Burette for accurate work
• Boroflo stopcocks have PTFE keys which do not require greasing
• The PTFE keys provide best drop control during titration process
• Due to identical shape of PTFE key the Burette valve can be closed with gentle turn.
• PTFE stopcocks have identical keys, hence there is no need to match pairs after cleaning
• PTFE is self lubricating hence the keys do not require greasing
• Specially designed solid glass stopcocks are manufactured from 3.3 Low expansion borosilicate glass
• Glass stopcocks are perfectly ground , hence no leakage occurs.
