Filters fine particles with high wet-strength and high loading capacity. Whatman™ Binder-Free Microfiber Filters, Grade GF/B are particularly useful for liquid clarification and liquid scintillation counting.

Combines high loading capacity with fine particle retention. Whatman™ Binder-Free Glass Microfiber Filters, Grade GF/A are ideal for gravimetric determination of airborne particulates, stack sampling and absorption methods of air pollution monitoring.

Served as the basis filter for EPA standard for the toxicity characteristic leaching procedure. Whatman™ Binder-Free Glass Microfiber Filters GF/F Circles offers an extremely high loading capacity and flow rate.

Contain no asbestos or fiberglass

Choose from six grades of filters. Glass Fiber Filters without Binders are made of borosilicate microfiber glass. Available in multiple pore sizes and flow rates for a variety of filtration and analysis applications utilizing depth filters. Autoclavable.

For prefiltration and contamination analysis

hydrophilic Glass Fiber without Binder Resin filter

Reinforce filters or use as spacers between filters. Filter Support Pads are available in absorbant cellulose pads to support filters in monitors or woven Dacron™ mesh spacers designed for use between filters. Available in diameters from 13mm to 124mm.

Perfect for measuring heavy metal concentrations and small amounts of particles

hydrophilic Glass Fiber with Binder Resin filter

Binder free filters

Designed for analysis of non-filterable residue and materials that require a high loading capacity glass microfiber filter. Whatman™ Binder-Free Glass Microfiber Filters, Grade 934-AH Sheets are also used in cell harvesting, liquid scintillation, and monitoring pollution.

Filters fine particles with high wet-strength and high loading capacity. Whatman™ Binder-Free Microfiber Filters, Grade GF/B Sheets are particularly useful for liquid clarification and liquid scintillation counting.

Binder-free glass microfiber filters for analytical and gravimetric analyses and prefiltering.

Multilayer graded density filters for rapid and efficient filtration of samples with high solids content. Whatman™ Glass Microfiber Prefilters are designed with a coarse glass filter top layer (10μm) meshed with a finer layer. The multigrade glass filter traps larger particles in its pores of the coarse layer, medium-sized particles in the interface meshing, and smaller particles in the interstices of the fine layer.

Glass fiber prefilters, depth pre filters, for larger totally filterable volumes in clarification and sterile filtration.

Binder-free glass microfiber filters for analytical and gravimetric analyses and prefiltering.

Combines fine particle retention with good flow rate. Whatman™ Binder-Free Glass Microfiber Filters, Grade GF/C are ideal for the collection of suspended solids in potable water, natural and industrial wastes.

Binder-free glass microfiber filters for analytical and gravimetric analyses and prefiltering.

High-purity quartz microfibers tempered for excellent weight and stability and especially suitable for emissions monitoring at high temperature.

Designed for analysis of non-filterable residue and materials that require a high loading capacity glass microfiber filter. Whatman™ Binder-Free Glass Microfiber Filters, Grade 934-AH Circles are also used in cell harvesting, liquid scintillation, and monitoring pollution.
