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
Included in delivery
- VB Series continuous E/RS, with GL 45 connecting threads and GL 32, GL 38 and S 40 (buttress thread) size PP thread adapters, telescopic filling tube (200 - 350 mm), telescopic discharge tube (140 - 220 mm), two 1.5 V microbatteries (LR 03/AAA), instruction manual, and quality certificate

* Error limits according to DIN EN ISO 8655-3. Accuracy (A) and Coefficient of variation (CV) refer to the nominal capacity
(= maximum volume) indicated on the instrument, obtained with instrument and distilled water at equilibrium
with ambient temperature at 20 °C, and with smooth, steady operation. DE-M marked.
** Volume dispensed per rotation of the hand wheel
