The VWR® E-Burette is a motor operated burette with sophisticated features and functionality. Motor controlled piston movement eliminates the errors associated with manual wheel controlled piston movement, thus facilitating correct and comfortable titrations. Having the capacity of 50 ml, this burette can be flexibly operated at 3 calibrated pre-set speeds, including dropwise dispensing for fine volume adjustment. This helps in achieving accurate end point of the titration experiment.

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.
