Esta buscando: Aspiradores

Aspirator bottles are used to sediment solid or suspended particles in liquid materials. The liquid is filled into the container, and after some time, the heavier solid particles deposit at the bottom of the aspirator bottle before the stopcock is opened to release the liquid into a collection flask. The autoclavable aspirators are made of borosilicate glass or heavy HDPE, with exceptional chemical resistance, minimal thermal expansion, and a high resistance to thermal shocks.
