BOECO Digital Continuous Bottle-Top Burette
BOECO Digital Continuous Bottle-Top Burette



The digital BOECO Continuous Bottle-top Burette makes manual titration safer, easier, with more reliable results. The DCB burettes can be used for titration agents up to a concentration of 2 Mol/l. During the titration process, the burette fills automatically, eliminating time-consuming refills.

Continuous pulse-free operation for faster titrations up to 5 ml per second. Titrant delivery is controlled by turning the wheels, and the amount dispensed is immediately shown on the display – from 10 µl to 999.9 ml, with a velocity of 2,5 ml/turn using model DCB 2500 or 5,0 ml/turn with model DCB 5000.

The DCB models eliminate the errors of reading the meniscus and volume graduations of conventional hanging glass burettes. There is no exposed glassware to break, and direct connection to the reagent bottle avoids pouring dangerous chemicals.
