Filtry membranowe z czarnego polieterosulfonu - Metricel™
Filtry membranowe z polieterosulfonu (PES) są hydrofilowe i odporne na działanie zasad, co sprawia, że są stosowane do próbek biologicznych i aplikacji w środowisku wodnym.
Metricel™ black PES membrane disc filters, a Pall Life Sciences product, provide excellent contrast for counting opaque colonies in microbiology labs.

Exclusive dot grid pattern does not enhance or inhibit colony growth

Certified for use in the Membrane Filter (MF) Technique as described in Standard Methods for the Examination of Water and Wastewater, current edition
Sharp contrast between black membrane and white grid line provides guidance while viewing and counting
Available non-sterile or in individual gamma-irradiated packs (S-packs) for critical applications
