Round 11: Tossup 12

In 2015, a Merck brand whose name references this process merged with Sigma–Aldrich. A “sterile” form of this process can be performed using a PES membrane fitted to a syringe. A component of BSCs performs a highly efficient form of this process through diffusion, interception, impaction, and electrostatic attraction. Diatomaceous earth aids this process by forming a “cake.” A Büchner funnel connected (10[1])to an (-5[1])aspirator (10[2])is used for the “vacuum” form (10[2]-5[1])of this process. (10[4])HEPA (“HEP-uh”) units perform this process, (10[1])which can also be performed using specialized paper with uniform (10[1])pore sizes to block particulate matter. (10[1])For 10 points, name this process of separating solids from a fluid. ■END■ (10[1])
