mdi Glassfiber sample pad type GFB exhibits high absorption capacity and does not bind proteins. It forms the platform where sample/analyte is placed at the time of testing. The non-reactive and non-binding properties of glassfiber material allows steady and uniform flow of analyte and prevents nonspecific binding of sample components to the pad.

GFB pads are available in standard thickness of 0.35 µm and 0.60 µm in sheet /strip form.

Specially impregnated pads can be offered to meet specific needs and for difficult to filter samples such as stool, milk etc.
