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
