The VWR® E-BURETTE has a ‘recirculation mode’ which prevents loss of reagents during purging and facilitates bubble-free dispensing. The delivery nozzle of the burette can be adjusted in both horizontal and vertical directions providing easy dispensing in demanding laboratory conditions.

The user-friendly TFT touchscreen guides quick and accurate titrations and displays numeric data up to the second decimal. A hand held stylus is provided as an accessory to assist touch operations on the control panel. The touch screen control panel can be used to perform functions like automatic re-fill without change of reading, zero reset, fill and dispense. The control panel is powered by a rechargeable, long lasting Li-ion battery. This battery can be easily replaced by the user.

The instrument has computer connectivity through a mini USB cable. It has a built-in software which allows readings to be transferred and saved in a file on the computer.
