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 to an aspirator (10[1])is used for the “vacuum” form of this (10[1])process. HEPA (“HEP-uh”) units perform this process, which can also be performed using specialized paper with uniform (10[1])pore sizes (10[1])to block particulate matter. (10[1]-5[1])For 10 points, name this process of separating solids from a fluid. ■END■
