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 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.

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.

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

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.

hydrophilic Glass Fiber without Binder Resin filter

Perfect for measuring heavy metal concentrations and small amounts of particles

hydrophilic Glass Fiber with Binder Resin filter

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.

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

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.

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

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.

Binder free glass microfiber filters are suitable for analytical and gravimetric analyses. They are also used as prefilter.

Offers fine particle retention and high flow rate, as well as good loading capacity

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.

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

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.

Especially suited for emission monitoring at temperatures of up to 900°C and wherever filters of the highest purity are needed.

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.

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

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.

Use in gravimetric analyses and as a depth filter for sterile filtration. Sartorius™ Glass Fiber (GF) Pre-filters, No Binder are made of borosilicate glass microfibers and combine fast flow rates with high load capacity. Ideal for relatively clean solutions, as it retains very fine particles.

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