Answer:ST 68 represents a 0.8 µm nominal pore-size cellulose acetate membrane.
Answer:The circles are 47 mm in diameter.
Answer:The package contains 100 Whatman ST 68 circles.
Whatman ST 68 cellulose acetate membrane circles offer a 0.8 µm nominal pore rating in the standard 47 mm disc format. The membrane is intended for laboratory filtration protocols that call for cellulose acetate chemistry and a pore size between the more open 1.2 µm ST 69 grade and finer 0.45 µm discs. Packs of 100 provide supplies for routine sample handling and repeat filter tests. ST 68 membranes can support clarification or defined particulate-retention work when compatible with the fluid and analytical method. The ST 68 name identifies a specific membrane grade; substituting membranes based only on diameter can change retention behavior. Use a suitable 47 mm holder and assess flow and sample compatibility for the application.
