Whatman™ 25mm 6901-2502 GD/X Sterile Syringe Filter with 0.2µm Cellulose Acetate

Description

Hard to find, I did some serious tracking to get a pure cellulose (media obtained from organic vegetation taken from nature) & specifically a cellulose acetate filter. This is the closest thing you can get to an organic STERILE filter (-a filter made from ingredients un-altered by human's) it's equivalent to organic fruit vs pesticide fruit except we don't know to much about the microscopic transfer at a level invisible to the naked eye of an all glass microfiber media to the filtered solution.
Each listing is for a single syringe filter that is said to filter up to 100ml each filter, though if you are filtering a mucky solution, the filter will clog much faster, where as if it is just water, it might never clog in which it has been estimated max efficiency is 100ml per a syringe filter, but I never personally viewed this theory. There are 20 filters currently for sale, I am willing to part with up to 50 filters. We can work out a price and new listing if more than 20 are needed.
Whatman™ 6901-2502 GD/X™ Sterile Syringe Filter with 0.2µm Cellulose Acetate Membrane, Diameter: 25mm
0.2µm Pore Size; Whatman™ GD/X™ 25 is the ideal syringe filter for the preparation of hard-to-filter samples
Cellulose Acetate Membrane Filter; Diameter: 25mm
GD/X™ 13 syringe filters can process three to seven times more sample volume than standard syringe filters
Whatman™ GD/X™ 25 syringe filter is specifically designed for high particulate loaded samples greater than 10mL in size
Exceptional loading capacity with fast flow rates; this prevents the build-up of back pressure typically caused by the blocking of an unprotected membrane

The Whatman™ GD/X™ 25 syringe filter is specifically designed for high particulate loaded samples greater than 10mL in size. GD/X™ syringe filters are constructed with a pigment-free polypropylene housing containing a pre-filtration stack of Whatman™ GMF 150 (graded density) and GF/F glass microfiber membrane media. The innovative, graded density of the GMF 150 pre-filter medium has a coarse top layer meshed with a fine bottom layer that retains particles to 1.0 µm. The GF/F filter then retains particles down to 0.7 µm. This innovative pre-filter stack is then followed with the primary filtration membrane. Whatman™ GD/X™ filters eliminate sample contamination and allow you to filter even the most difficult samples with less hand pressure. GD/X™ syringe filters can process three to seven times more sample volume than standard syringe filters. The syringe filter construction facilitates exceptional loading capacity with fast flow rates. This prevents the build-up of back pressure typically caused by the blocking of an unprotected membrane. Membrane: Cellulose Acetate. Retention: 0.2µm. Filtration Area: 4.6cm². Diameter: 25mm. Inlet: Female Luer Lock. Outlet: Male Slip Luer. STERILE. Whatman™ #: 6901-2502.
