Adapter (of the aspirator)

ADAPTER (EN: prolong, adapter; DE: Allonge; FR: allonge; ES: alargador, prolongador; RU: аллонж) is the container for the collection of the dust in the aspirator.

The design of the adapter is determined by the type of the filter, which is used for the deposition of the dust; the most common design in the mining craft is the cartridge (of the metal or plastic) of the cone-like shape. The filter (analytical aerosol, membranal, and others) is hermetically fixed at the widest part of the cartridge. There is used during the usage of the absorbent cotton filters the glass adapter in the shape of the pipe with the wide inlet and narrow outlet openings, which are tightly closed by the ground glass stoppers before and after the collection of the sample.
