Liquid dispenser!

The Deeter Group has introduced a new Low Volume Liquid Dispenser.  Intended for accurate, repeatable dosing of small volumes of chemicals, colours or flavourings. The Low Volume Liquid Dispenser may be used to control any liquid being dispensed in a laboratory or manufacturing process.

The new Low Volume Liquid Dispenser is designed to deliver a measured volume of liquid at the press of a button.  In normal use, the operator selects a volume, presses a button and the Dispenser delivers the required volume without further operator intervention.  The volume required is simple to set and the dose is retained in non-volatile memory for repeat operations. Volumes between 0.025 litres and 10 litres can be selected in increments of 0.001 litres.

The Dispenser will accurately measure volumes over a flow rate range of between 0.2 litres/minute and 2.5 litres/minute and will automatically compensate for the effects of varying flow-rates and changes in liquid temperature.  A calibration menu allows fine adjustments to the compensation.

The Low Volume Liquid Dispenser has two John Guest Speedfit® 8mm push-fit connectors for input and output of fluids.  Wetted surfaces are nylon, PTFE, Buna and acetyl, making the Low Volume Liquid Dispenser suitable for a wide range of fluids over a temperature range of +1 to +65ºC.  Operator controls consist of a three-button keypad and a liquid crystal display.  The display shows the selected volume and progress during dispensing.  A number of additional features are available through the keypad, including pause and restart during dispensing, cancelling dispensing, and manual ‘top-up’ control.

Peter Whiteaker, Managing Director of The Deeter Group comments; "We have over twenty years of experience in designing fluid dispensers and our new Low Volume Liquid Dispenser will be ideal for single users in laboratories to automated systems for low volume dosing.  This new design features temperature controlled accuracy and the convenience of having software provided for control and monitoring from a PC.”

The Dispenser has a serial communication option to enable automated control and monitoring by an external computer using the software provided.  Communication is via USB ‘A to B’ cable and the Low Volume Liquid Dispenser is powered by a low-voltage supply, making it safe to use in damp environments or if liquid is spilt.  A 12VDC mains socket adapter is supplied with each Dispenser.

An audible ‘beep’ option is provided to indicate when dispensing has stopped and a further option will produce continuous ‘beeps’ if the flow rate is outside of  the limits for accurate volume measurement.  These audio options can be enabled or disabled through a display menu and are also saved to non-volatile memory and are restored to the operator’s preference after power-up.
