HF bottle top dispenser is designed with selected materials for barrel and valve assembly that enable the dispenser to be used with Hydrofluoric Acid (HF) in addition to solvents and other reagents.

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.
