<p>A syphoning device for small amounts of liquid in e.g. a bottle or flask, uses two transparent tubes joined at one end to a three way connection (3). One tube (2) is bent over to extend into the bottle (13) and the other tube (4) is the suction tube. The discharge from the three way connection may be closed by finger pressure, or fitted with a valve (10). In one design, the first tube (2) may carry a cork to fit in e.g. a flask, and instead of the user putting the suction tube in his mouth, a bellows type pump may be fitted.</p> |
