Our comprehensive range of ultrafiltration membranes offers the flexibility to optimize your concentration and buffer exchange processes for most macromolecules. Available in a variety of diameters, these membranes are ideal for use in stirred cells and custom applications.
Cellulose Triacetate (CTA)
The absence of a substructure in these membranes reduces trapping of passing micromolecules, making them ideal for applications where the permeate will be analyzed, such as fractionation and deproteinization.
Hydrosart® Regenerated Cellulose (RC)
These autoclavable membranes are easy to clean and have been developed for the biopharmaceutical industry to be non-binding and virtually non-fouling. They are often preferred for dilute and high-value samples.
Polyethersulfone (PES)
Exhibiting no hydrophobic or hydrophilic interactions, these high-flux membranes deliver excellent concentration and buffer exchange performance in a wide range of research and biotechnology applications.
