Digital burette VB Series

Continuous bottle-top burette enables continuous titration

The VB Series continuous bottle-top burette enables continuous titration, which leads to rapid, convenient, and accurate results.

Features

The angled display shows 4-position titration volume in large, easily read numbers, which simplifies operation
Turning the two hand wheels supplies the titration medium in a continuous and pulse-free manner via the patented double-piston pump (EP 801 982)
Filling procedures are not necessary
This innovative technology increases safety; its compact design and low centre of gravity reduce risk of overturning, especially with smaller bottles
The height and length of the discharge tube can be adjusted, making it possible to work safely with both short and tall bottles
The patented recirculation system (EP 542 241) prevents the loss of valuable reagent and reduces the risk of splashes
With its simple-to-use calibration function, VB Series continuous fulfils the corresponding requirements for test equipment monitoring without instrument downtime
Margins of error are under those specified in the DIN EN ISO 8655-3 standard, even for partial volumes
VB Series continuous is DE-M marked
