These borosilicate glass filters are suitable for water quality parameter measurement and air filtration applications. The can be used for high-efficiency general purpose laboratory filtration, including water pollution monitoring of effluents, for filtration of water, foodstuff analyses, protein filtration, and radioimmunoassay of weak β emitters.

Supplier: Cytiva

Cytiva's Whatman Grade 542 filters are acid hardened to allow high retention of fine precipitates in applications such as metal determinations and hydroxide collection.

Supplier: Cytiva

Designed for use in vacuum and pressure filtration applications. Filters feature an unsupported Anopore® membrane disc compatible with a wide range of organic chemicals, solvents and aqueous solutions, eliminating the need for multiple filter types. Ideal for microscopic analysis because of its sieve-like properties and virtual transparency when wet.
