The Whatman™ GD/XP non-sterile polyethersulfone (PES) membrane syringe filters are designed to prepare and enhance the inorganic ion analysis of hard-to-filter samples greater than 10 mL. Each unit contains a prefiltration stack of polypropylene prefilters and PES membrane.
Increase flow rates and reduce blockage as a result of the two layer prefilter stack
Eliminate sample contamination
Requires less hand pressure, even for samples with a high level of particulates
Process three to seven times more sample volume
Reduce costly exchanges with extended filter life
Applications
HPLC sample preparation
Trace metal analysis
Sample preparation prior to dissolved heavy metal
Polyethersulfone (PES) membrane considerations
This carefully selected Polyethersulfone membrane meets the special filtration requirements of durability, high temperature resistance, good chemical compatibility, and low protein adsorption. It is particularly suitable for filtration of serum, plasma and tissue culture solutions as well as other protein containing solutions where minimal adsorptive protein loss is desired.
