<p>Accurate dispensing of liquids via a dispensing tube (5) uses an air jet (11) to remove droplets from the end of the tube especially at the end of a dosing cycle, where the air jet is supplied with a pressure pulse of between 0.001 and 0.1 seconds, and two air jets are used with different orientations for effective removal of droplets. A method for accurate dispensing of liquids via a dispensing tube (5) uses an air jet (11) to remove droplets from the end of the tube especially at the end of a dosing cycle. The air jet is supplied with a pressure pulse of between 0.001 and 0.1 seconds. At least two air jets are used, with different orientations for effective removal of droplets. For more effective removal the pressure pulses from the two jets are offset and overlapping.</p> |
