Ensuring safe, convenient, and accurate titrations
Bottle-top burettes deliver a gradual and controlled volume of reagent directly from a supply bottle to the burette cylinder. This ensures precision, supporting consistent and reproducible titrations. In addition to their accuracy, bottle-top burettes offer safety, ease, and efficiency. These lab instruments minimize the risk of spills or exposure to hazardous chemicals, and they also eliminate the need to transfer reagents between containers, streamlining workflows and reducing cleanup.
Two models for different dispensing speeds
To accommodate different titration needs, the Eppendorf Top Buret is available in two different models: Model M, with a dispensing rate of 2,500 µL per rotation; and Model H with a rate of 5,000 µL per rotation.
Why buy an Eppendorf bottle-top burette?
The Eppendorf Top Buret is a bottle-top dispenser that features continuous, pulse-free dispensing of titration solutions. This lab device is precise, easy to use and sets new standards in manual liquid titration. Users simply set the desired volume on the intuitive digital bottle-top burette, and with each turn of the wheel, liquid is continuously and precisely dispensed. There is no need for new liquid aspiration, making titration simpler and safer, and with a clearly labelled and user-friendly digital display ranging from 10 µL to 999.9 mL - the size of your supply bottle is your only limiting factor!

Robust, versatile, and easy to use, time after time
This digital bottle-top burette is extremely robust, with the ability to dispense a wide range of reagents, including diluted salt solutions, and diluted acids and bases in concentrations up to 1 mol/L. Its ergonomic design and simple control wheels guarantee easy and fatigue-free operation, while the thread has been designed with maximum versatility in mind. The dispenser thread connection is made to fit standard 45 mm bottle threads. However, a variety of different thread adapters and further accessories are available to help ensure the Top Buret meets your specific dispensing needs. You can find more information on Top Buret applications and best practices in
our whitepaper.
How to use an Eppendorf Top Buret bottle-top burette
Adjust the telescopic aspirating tube to your bottle height before attaching the burette to the bottle with the appropriate adapter. Vent the burette by turning the discharge valve toggle to the side, removing the control panel and turning the dispensing wheel forward until all air bubbles have visibly left the system. Turn the discharge valve toggle back to the front, turn the dispensing wheel until liquid comes out of the discharge tube and re-attach the control panel. Press start to start a new titration flow. The burette automatically turns off after a few minutes. Learn more in our
tutorial video and by reading the
operating manual.
