Witeg Digital Burette / Bottle-Top Burette TITREX

Buy Witeg products from MSE Supplies at the best value.

Description

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.

Features

Quick and precise volume setting: The dispensing and titration volume can be set by turning the handwheels. The mode can be changed by pressing „DOS“ respectively „TIT“. The display shows the emitted volume („TIT“ mode) respectively the filled volume („DOS“ mode).

Perfect air-purging mechanism for 0% reagent loss: Turn the discharge tube at 90°. Remove (purge) trapped air without reagent loss by pumping in a closed circuit. The reagent flows back into the bottle! After pumping 2 - 3 times the dispenser is free of air and ready to use. This special feature helps not only to save residual reagent but also when accidentally setting the wrong volume!

360°-turn for your added safety: No matter how much you tighten TITREX, you can always redirect the discharge tube by simply turning the valve block to the desired position. This way the label of the bottle is always visible. This feature works for all our adapters. Adapters for different bottle threads can remain on the bottle.

100 % drip-free system for your safety: By turning the discharge tube at 180° all liquid flows back into the bottle. TITREX is completely closed and no accidental discharge can occur by inadvertently moving the piston. There is absolutely no dripping possible!

“Do-it-yourself” recalibration for a long life time: If you use TITREX as a measuring device in conformity to ISO 9001 and GLP, you need to control and monitor its accuracy and reliability. Therefore you can easily recalibrate the value by pressing „CAL“ until the display shows „CAL“. With the buttons „+“ and „-“ you can now adjust and correct the value. TITREX can also be adjusted to liquids with other density and viscosity. TITREX can also be recalibrated with the included TITREXSOFT.

“TITREXSOFT: Through the access to the TITREX’ memory, all data can be transferred to a PC – no more transmission errors! The completely new developed software helps to process the stored data. Saved values can be read-out in real-time during the titration process or afterwards. Via the protocol export function, the data together with the automatically created graph can be either printed or saved.

The components having direct contact with the reagent are made of chemical resistant materials: spring, ceramic valve balls, PTFE piston, borosilicate glass 3.3 cylinder, borosilicate glass 3.3 valve
