GLASS MICROFIBER FILTER
COMPANY : WHATMAN, ENGLAND.

Glass glass microfiber are manufactured from 100% borosilicate glass and are
chemically inherit and completely binder free. These depth filters combine fast 
flow rates with high loading capacity and the retention of very fine particles,
extending into the sub-micro range.

GF/C : Regularly specified in standard methods for determining suspended 
solids in water, removal of turbidity and filtration of bacterial cultures.

GF/F : Very high retention for filtering fine particles.
