Electrical pipette Witopet EP Single-Channel

Looking for the most comfortable way of pipetting? The electronic microliter pipette WITOPET EP is the right product for you. The motorized pipetting process has at least two major advantages compared with manual pipetting: it avoids pipetting errors user induced and it prevents the risk of a cramp after prolonged pipetting phases. WITOPET EP is available as single- and multi-channel pipette.

Your advantage at a glance:

ideal for prolonged pipetting
minimal pipetting forces required
automatic pipetting process for highest comfort and accuracy
multiple functions (auto-pipetting, mixing, multiple dispensing, sequential aspirating / dispensing)
9 memory settings
5 speed settings for different viscosities
user friendly digital display
360° rotatable pipetting unit for more flexibility (multi-channel only)
including Li-ion 3,6V 1000mAh battery
serial number and CE label
individual certificate according to DIN EN ISO 8655-2
DE-M marked according to the German calibration law

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
