Aspirator Bottle

Aspirator bottles are used to sediment solid or suspended particles in liquid materials. The liquid is filled into the container. After some time, the heavier solid particles deposit at the bottom of the aspirator bottle and the stopcock is opened to release the liquid into a collection flask. These DULAB™ aspirator bottles have a tubular sidearm outlet near the bottom for attachment of flexible plastic tubing and are very useful as a delivery/storage container for solutions. These bottles feature sturdy ring necks with a heavy duty rims and rubber stoppers.
