vacuum filtration

The Grootegeluk plant uses horizontal belt vacuum filtration to dewater fines.

To dry product use vacuum filtration using a Buchner funnel, a water aspirator, and fine porosity filter paper.

Specialized microplate washers also exist for bead-based assays using biomagnetic separation or vacuum filtration.

Each sample must be pretreated with heated 2 N HCl followed by rinsing with deionized water and vacuum filtration.

Crystallization can then be induced from this supersaturated solution and the resultant pure crystals removed by such methods as vacuum filtration and centrifugal separators.

The flasks are used to cooperate with vacuum aspirator or vacuum pumps in the vacuum filtration, or as additional security during the distillation and other processes carried out under reduced pressure.

Sales of Smoketrapper, a battery-operated smokeless ashtray that comes with its own vacuum filtration system, are up, according to Jeannette Orel, the Los Angeles-based creator of the ashtray.

Though he characterized himself as "brand neutral," Mr. McNulty uses a Eureka vacuum, a self-propelled, 12-amp "Smart Vac" model with a 15-inch cleaning path, a "True HEPA" sealed vacuum filtration system, a headlight and onboard tools.
