Operation Manual for
VP 548-US
Ultrasonic Wash
Station
Introduction
This is the user manual for the
VP 548-US
ultrasonic wash station. This wash station is designed for
cleaning plastic tips, needles and pins used in liquid handling applications. It has a standard SBS
microplate footprint and is designed to fit on the deck of most liquid handling robots. It uses high
frequency ultrasound to generate an oscillating cavitation field in a liquid bath. This is an effective
means of removing organic material that is attached to hard surfaces. The
VP 548-US
is equipped
with a weir system to provide a constant level of wash liquid and to prevent overflows.
Safety
1. Do not attempt to open the ultrasonic tank (which contains the ultrasonic generator) or control and
pump unit. There are high voltages present and there are no user serviceable parts.
2. Water is an effective cleaning agent in an ultrasonic bath. You may add to this a surfactant or a
miscible organic solvent. The solution must be at least 50% water.
Note:
The tank has not been tested with a range of organic solvents. Operators MUST ensure that
the use of solvents in the wash station has been sufficiently investigated such that a hazard is not
caused. Operators must also ensure that the solvent mixture does not damage tubing, electrical
cables or fittings. V&P recommends that water should be used wherever possible. V&P accepts no
responsibility for damage or loss if solvents other than water are used.
