Round 10: 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, (10[1])impaction, and electrostatic attraction. Diatomaceous earth aids this process by forming a “cake.” A Büchner (10[1])funnel connected to an aspirator (10[1])is used for the “vacuum” form (10[1]-5[1])of this (10[2])process. (10[2]-5[1])HEPA (“HEP-uh”) units perform this process, (10[1])which can (10[1])also be performed using specialized paper with uniform pore sizes to block particulate matter. For 10 points, name this process of separating solids from a fluid. ■END■ (0[2])
