Assembly of the vacuum filtration apparatus used for the Dry Weight Assay (Basic Protocol 7). The filtration device is assembled by placing the rubber cork on a flask (A), followed by the plastic O-ring (B), the wire filter sieve (C), and the mixed cellulose ester membrane (D) (in this order from bottom to top). The funnel (E) is then added on top and the clamp (F) is attached to keep all components together. The clamp should cover the top of the glass piece (A) as well as the base of the funnel (E).
