Speed Pack

Speed Pack membranes are stacked, sterile 47 mm nitrocellulose discs made for use with a membrane dispenser. High-volume water testing laboratories use Speed Pack discs to filter many samples quickly while keeping each membrane sterile until it is dispensed.

Ten GVS listings cover white gridded discs in 0.22 µm and 0.45 µm pore sizes, supplied in packs of 150 or 600. The grid aids colony counting after incubation and the stacked format loads directly into the GVS membrane dispenser, with sterile polypropylene cups listed separately.

Choose 0.45 µm for routine coliform and heterotrophic counts and 0.22 µm when finer retention is required, then size the pack to your weekly throughput. Ask Lancetech Limited for a quotation on Speed Pack discs together with the dispenser and cups.
