Print PageWhatman Cyclopore membranes are true pore size microporous membranes featuring sharp cut-off and reproducible microfiltration performance characteristics.
Membranes are produced from a pure polymeric film and give exceptional chemical cleanliness. They are free of contamininants, have low tare weight, minimum water adsorption and very low levels of non-specific protein binding.
Available in polycarbonate for most applications Whatman Cyclopore membranes are an ideal choice whenever particles must be accurately separated by size and then measured, counted, recovered or transferred.
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.
