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.

Generally used for air and gas monitoring, but are suitable as a prefilter.

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

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.

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 for analytical and gravimetric analyses and prefiltering.

Grade GF/C glass filters offer fine particle retention, good flow rate and loading capacity, and support total suspended solids analysis.

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.

Sartorius Stedim Biotech™ Glass Fiber Pre-Filters are suitable for liquid filtration, prefiltration, and analytical sample preparation.

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

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.
