Cell. mixed ester membr. filters 0.2 µm, sterile, Ø 47 mm, with grid

Cellulose mixed ester membrane filters with a pore size of 0,2 µm and a diameter of 47 mm are sterile discs printed with a grid to support colony counting and positional reference after filtration. The finer 0,2 µm pore size is chosen for applications that demand tighter retention than 0,45 µm membranes, including sterile filtration and microbiological sample work. Grid markings on the membrane surface assist enumeration and documentation under standard laboratory lighting or colony counters. Packs contain 100 sterile 47 mm filters suitable for common vacuum and pressure filter holders. These membranes come from manufacturer Cytiva and are intended for filtration and separation routines in research and quality-control laboratories. The cellulose mixed ester construction is a established membrane type for aqueous laboratory samples. With a pack weight of 0,124 kg, the product is easy to keep on hand for repeated sterile filtration runs. This gridded, sterile 0,2 µm format combines a defined pore geometry with a counting grid for membrane-filter workflows that require both fine retention and clear spatial orientation on the disc.
