Membrane filter, CN, type 130, grey with white grid, non sterile, 100 pcs

Cellulose nitrate membrane filter, type 130. Cellulosic nitrate is the material that provides effective retention at high flow rates and optimal colony growth. The printed grid, with 3.1 + 3.1 mm squares, facilitates the counting, especially at higher counts and microcolonies, but does not affect growth. Gray membranes (after wetting black) with white grid, for the detection of yeasts and molds, particle analysis and microscopy. Non-sterile and individually sterile packed deliverable.
