Superior grade glass fibre filters for a variety of air sampling methods. Used in a variety of sample clean-up, prefiltration and analytical testing applications.

Type A/B: Binder-free borosilicate glass microfibres. For diagnostic applications and sample prefiltration. High loading capacity with 2,5 times thicker glass than type A/C.
Type A/C: Binder-free borosilicate glass microfibres. For testing dissolved and suspended solids in wastewater, for cell harvesting applications and prefiltration.

Type A/D: Binder-free borosilicate glass microfibres. Excellent prefilters for solutions with a heavy load of charge sized particulate.

Type A/E: Binder-free borosilicate glass microfibres. For testing dissolved and suspended solids in wastewater and for gravimetric analysis of air pollutants. High flow rates, wet strength and solids holding capacities. Aerosol retention (0,3 µm DOP): 99,98%.

'Extra Thick': Borosilicate glass microfibres with acrylic binder. For prefiltration of viscous biological solutions and heavily contaminated samples. High particulate-holding capacity makes discs efficient depth filters and allows for filtration of large volumes of solutions. Aerosol retention (0,3 µm DOP): 99,97%.

Type Metrigard™: Ultrafine glass fibres with acrylic binder. For prefiltration in systems with high particulate matter to prolong membrane filter life.
