  • 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 1 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.
  • Safety recirculating valve allows for recirculation within the closed system to avoid reagent waste.
  • Angled digital display for easier reading from different heights by different users.
  • Unique telescopic intake tube with length from 210 till 310 mm can be re-adjusted without cutting for different bottle sizes.
  • Dosing spectrum from 10 µl to 999.9 ml.
  • Battery-operated, easily replaceable micro-batteries 1.5 V (LR 03/AAA). One charge lasts a minimum of 500 hours (dispensing 4500 l of reagent).
  • Burette can be rotated 360° on the bottle.
  • Titrating tube removable and adjustable: horizontal 142-220 mm, vertical 10-200 mm.
  • Service friendly modular assembly.
  • Electronic can be completely removed.
  • Low battery indicator.
  • User-serviceable and calibratable to meet ISO and GLP requirements.
  • Optional drying tube protects reagents from moisture or CO2.
  • Manufactured under ISO 9001 norms.
  • Adapters are available to fit most bottle neck sizes.
