The Whatman lab filtration range from Cytiva includes a variety of glass fiber filter materials suitable for use in several applications such as nucleic acid extraction, environmental monitoring, and even used as battery separators. They vary in particle retention size, thickness, weight, porosity and wet burst. Each of these materials is manufactured to the same high standards. Please refer to the table for an overview of the different properties of glass fiber filter versus cellulose and membrane filters.
