The accessory pack, Stock# P48AP, contains several items to facilitate handling and staining polycarbonate membranes. It includes a filter wiper that may be mounted on a ring stand, one large and one small filter clamp, and two pairs of curved, stainless steel forceps. The implements are used to wipe non-migrated cells off the top of a filter and while fixing and staining the migrated cells.
