The conditioning cartridge is for use in PURELAB® Option-E 5/10 water purification systems, for the conditioning stage required for reversed-phase sorbents.

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.

Vacuum filter systems available in four sizes: 150 ml; 250 ml; 500 ml and 1 L. Adapters are colour coded by membrane type for easy product identification: Polyethersulfone (PES) yellow; cellulose acetate (CA) orange; cellulose nitrate (CN) blue; nylon (NY) red.

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.

Cartridge tubes and end caps are constructed of 100% virgin polypropylene and are designed for non pressure applications.

Organic carbon filter, Type AC. It contains 12 pounds of granular activated carbon media suitable for organic solvents including acetone, ethyl acetate, toluene and xylene.

These cellulose filter papers are intermediate in speed and retention between grades 1 and 4.

Quality paper for general chromatography and electrophoresis.

The most widely used qualitative filter paper for routine applications.

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.

Perfect for your paper chromatography needs.

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.
