Description
Compatibility

The Cellulose Nitrate Membranes are recommended for the majority of routine applications, these membranes are manufactured under strictly controlled conditions.

The user will benefit from the performance improvements which are now available including very narrow pore size distribution and low levels of extractables.

Higher strength and Flexibility
Low extractable levels
Narrow pore size distribution
Increased temperature stability
Reduced shrinkage

Applications:

Sample preparation
Microbiological studies
Filtration of aqueous solutions

Guide to…Membrane Filter Properties

Identifying the filter material most suitable for your application based upon the nature of the liquid or gas you are filtering will ensure the best performance of your filter. Each membrane filter material has differing chemical and physical properties such as hydrophobicity, flow rate, extractables and protein retention making them suited to differing applications. Once you have selected the most compatible filter material, you will need to consider what pore size is most appropriate.

Membrane Material	Protein binding	Hydrophilic/Hydrophobic	Chemical resistance	Applications
