Uses include filtration of aluminum phosphate, zinc ammonium phosphate, and silver chromate.

Suitable for filtration of aluminum phosphate, barium carbonate, lead chromate, and more.

By choosing an ELGA water purification system, you are making an investment in quality, reliability and value.

Syringe filters are available with a choice of membrane type: Polyethersulfone (PES) for low protein binding and faster flow rates; surfactant-free cellulose acetate (SFCA), with or without prefilter, for lowest protein binding; Polytetrafluoroethylene (PTFE) for chemical resistance; regenerated cellulose (RC) – the best choice for DMSO compatibility; and nylon (NY) which is hydrophilic, surfactant-free and lowest extractable.

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.

A good quality paper recommended for student use and all routine filtering operations. This is a strong filter paper with a medium flow rate and retention.

Whatman chromatography papers are widely used across the world, reflecting their purity, high quality and consistency. They are made from specially selected cotton cellulose and rigorously quality controlled to ensure uniformity within the grade.

High Quality Filter Paper.

Quantitative filter papers are used for gravimetric analyses or filtrations where the precipitate is to be recovered.

Qualitative Filter Paper is available in three standard grades.

Whatman Grade 4 Qualitative Filter Papers are a standard grade, high flow rate filter paper. They are useful in qualitative analytical separations when fast flow is required and the collection of fine particles is not critical.
