Disp.Filter Funnel, 47 mm

Disp.Filter Funnel, 47 mm units are disposable filter funnels with the membrane already fitted. Microbiology and water testing laboratories use them to cut handling steps and reduce contamination risk during membrane filtration.

The two GVS SAVUR funnels listed differ in membrane: one holds a sterile white gridded nitrocellulose membrane at 0.45 µm, packed 12 per pack, for coliform and total count work; the other carries a 25 µm polypropylene membrane in packs of 200 for coarse pre-filtration or particulate checks. Both use the common 47 mm format, so they fit standard manifolds and filter holders.

Pick the 0.45 µm gridded version for colony counting and the 25 µm polypropylene version where only larger particles need to be retained. Send Lancetech Limited a note with your pack quantities for a quotation.
