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.

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.

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.

Woven mesh spacers are placed between filters in serial filtration to prevent the downstream screen filter from 'blinding' the upstream filter pores. They increase flow rate & throughput.

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.

A standard filter for the clarification and monitoring of waste water and water, scintillation counting on the filter, cell harvesting and hydrocarbon analysis where cellulose fibers are an inconvenience.

For prefiltration and contamination analysis

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.

Functions as a prefilter when used with GF/B microfiber filters. Whatman™ Binder-Free Glass Microfiber Prefilters, Grade GF/D provide efficient membrane protection, especially during liquid scintillation counting.

Provides strength, efficiency, reliability and consistency of data quality in continuous air monitoring.

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.

Ready to use, Grade 934-AH RTU Glass Microfiber Filter Papers are the time-saving version of GE’s 934-AH glass microfiber filter papers, which are widely used for total suspended solids analysis.

Useful for the analysis of acidic gases with the exception of hydrofluoric acid.

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.

Hydrophilic Glass Fiber without Binder Resin filter

Hydrophilic Glass Fiber without Binder Resin filter

Widely used for total suspended solids analysis.

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.

Use as a depth filter for larger totally filterable volumes. Sartorius Glass Fiber (GF) Pre-filters are made of borosilicate glass microfibers and are ideal for use as a pre-filter in clarification and sterile filtration. Available in a range of filter disc diameters.

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.

Grade GF75 Glass Fiber Filters for analytical or gravimetric studies.
