Supplier: Cytiva

Whatman PTFE membranes from Cytiva are strong hydrophobic membrane filters resistant to the corrosive solvents and aggressive media used in gas sterilization and liquid clarification.

Supplier: Cytiva

Whatman mixed cellulose ester membranes are composed of cellulose acetate and cellulose nitrate. These membranes are characterized by a smoother and more uniform surface than pure nitrocellulose filters.

Supplier: Cytiva

Membranes are made from pure cellulose acetate, making them ideal for biological and clinical analysis, sterility tests, and scintillation measurements. Filters exhibit very low protein binding capacity and are hydrophilic, making them suitable for aqueous and alcoholic media. The cellulose acetate membranes have improved solvent resistance, particularly to low molecular weight alcohols, and increased heat resistance. The membrane filters exhibit high physical strength and can be used up to 180°C (356°F), making them suitable for hot gases and allowing them to be sterilized by all methods without sacrificing the integrity of the membrane.

Supplier: Cytiva

Suitable for use in a wide range of specialized applications, including HPLC mobile phase filtration and degassing, bacterial analysis by epifluorescent light microscopy, ultra cleaning of solvents, gravimetric analysis, and liposome extrusion.

Supplier: Cytiva

For preparing HPLC samples and solvent clarification. Ideal for both aqueous and nonaqueous solutions. Very low extractables, minimizing the risk of introducing spurious peaks in HPLC analyses. Excellent chemical compatibility with common solvents, bases, and esters.

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.
