The same filtration media that is die cut into discs and packaged as the
SPI-Pore membrane filter discs, can also be cut up from the original "rolls"
of material into cut sheets. The standard size is 8 x 10" (200 x 250 mm)
but on special order, just about any size can be provided. Caution: There
are substantial minimum quantities required for such special orders.
Also note that all membrane material has been treated with polyvinylpyrrolidone
(PVP) as a wetting agent, something highly desirable for most users. The product
can be procured as a special order without PVP treatment.
