Sipper tube with ultrasonic debubbling
First Claim
1. A device for extracting a bubble free sample from a liquid containing bubbles comprising:
- an ultrasonic transducer;
a sampling tube having two ends mounted at a first end to said transducer and having an inlet port at a second end;
wherein ultrasonic energy from said transducer is transmitted through said sampling tube from the first end to the inlet port whereby when said sampling tube is immersed said liquid containing bubbles, bubbles are forced away from the inlet port; and
extraction means for removing a liquid sample through said sampling tube.

Abstract
The invention is a sampling device (4) and method used to remove bubble free samples from a bubble laden liquid. The device includes a power supply (10), a transducer (6) and a sampling probe (5). The power supply (10) converts normal line voltage to 20 kHz electrical energy. This high frequency electrical energy is converted to mechanical vibrations via the piezoelectric transducer (6). These mechanical vibrations propagate down the sampling probe (5) and emanate from the tip of the probe in the form of ultrasonic waves. The ultrasonic waves emanating from the probe tip serve to push away air bubbles from the vicinity of the tip. This allows the removal of a bubble free sample from the bubble laden liquid for further analysis.
