Solid Phase Extraction Frits and Filters

Frit Selection Guide

Frits are friction fitted within the cartridge to retain the sorbent, and also to perform a variety of filtration functions. Applied Separations’ porous plastic frits are naturally hydrophobic, but aqueous solutions can be forced through under pressure. If gravity flow of an aqueous solution is desired, then select a specially treated polyethylene hydrophilic frit.

Hydrophobic Polyethylene

Hydrophobic Polyethylene frits are the standard and are used in most commercial SPE products. They are also used with non-aqueous solutions such as solvents, alcohols, acids, bases, halogenated and aromatic hydrocarbons and ketones. These hydrophobic frits can be wetted with organic solvents.

Hydrophilic Polyethylene

Polyethylene hydrophilic frits are used for general filtration and as clarifications of aqueous solutions and certain other solutions. These hydrophilic frits are specially treated and can consequently be wetted with aqueous solutions. This frit is ideal for gravity flow of an aqueous solution.
