Gridded Membrane Discs

By Sartorius

Gridded membrane filters are used for colony counting, sterility testing, particle testing & microscopy with a pore size ranging from 0.2-1.2 um. These membrane filters are available in sterile, non-sterile and for use in dispensers.

All membranes are made of cellulose nitrate (cellulose ester), a material which assures effective retention with high flow rates and optimum colony growth. The printed grid divides the filtration area into 130 squares; each measuring 3.1x3.1 mm makes the counting easier, especially for higher bacteria counts and for microcolonies, without influencing microbial growth. The three various filter colors, green, white and gray (after wetting black), allow the best contrast to the colonies.
The HighFlow gridded membranes have 30% higher flow rates in comparison to traditional 0.45µm membranes .The special pore structure of the new 0.45µm HighFlow membrane filters allows shorter filtration times due to higher flow rates and throughputs.

Non-Sterile Gridded Membrane Discs

Membrane Filters for Colony Counting, Particle Testing and Microscopy. Membranes are Cellulose nitrate (cellulose ester), gridded, non-sterile.

Type 114 - White membrane with black grid for detection of bacteria with dyed media
Type 139 - White membrane with green grid for detection of bacteria with dyed media
Type 138 - Green membrane with dark green grid, providing optimal contrast to light -colored or transparent bacteria colonies
Type 130 - Gray membrane (after wetting black) with white grid for detection of yeasts and molds

High Flow, Sterile Gridded Membrane Discs

The High Flow cellulose nitrate membranes have 30% higher flow rates in comparison to traditional 0.45µm membranes .

The special pore structure of the new 0.45µm HighFlow membrane filters allows shorter filtration times due to higher flow rates and throughputs. As with every Sartorius 0.45µm membrane filter lot, these membranes are also tested and released according to ISO 7704.
