Digital burette / bottle-top burette TITREX
Digital burette / bottle-top burette TITREX

The digital burette TITREX is ideal for a fast and sensitive titration “drop by drop”. One instrument simulates all volumes up to 99.99 ml. Moreover, titration is possible without any loss of reagent! From air-purging, necessary for a precise titration, to disassembly of the burette in the end of the titration – the reagent, that is not needed for the titration flows back into the bottle! TITREX‘s accuracy and precision are of highest quality. Our error ranges are better than those required by ISO 8655-3. The memory function allows saving of up to 1000 values, which can be transferred to a PC and read using the included software.

Your advantage at a glance:

  • high quality precision instrument, made in Germany
  • highest accuracy and precision, our error ranges are better than the DIN EN ISO 8655-3 requirements
  • resistant against most acids and alkalis
  • exclusive instrument with 0% loss of reagent - air-purging and draining within a closed circuit
  • 360° rotatable valve block for your added safety
  • two-in- one instrument: dosing & titration
  • covers the complete volume range up to 50 ml when used as a dispenser and up to 99.99 ml when used as a burette
  • easy and precise volume setting
  • vertical valves: no sedimentation, no contamination
  • 100 % drip-free by turning the cannula at 180°
  • no transcriptions errors due to automatic value storage and the possibility of
  • transferring values to a PC via RS232 interface (USB adapter optional available)
  • calibration: standard with water of 20°C
  • software enables saving the next calibration date
  • recalibration for liquids of different viscosities possible e.g. determination of acid content in milk
  • easy to dismantle and to clean, valve block autoclavable at 121°C
  • automatic power-cut-off after three minutes
  • including NiMH 1,2V 2100mAh battery
  • individual certificate, CE label and serial number
  • DE-M marked according to the German calibration law
