Filtration media

CA Filters

Composition: Mixture of triacetate and diacetate
Characteristics:Low static charge and high strhgth
Sterilizable: May be repeatedly sterilized without loss of integrity or change in bubble point
Clean: 0.1 wt% aqueous extractables

Related to MCE membranes: - improved solvend resistance to low molecular weight alcohols - better heat resistance - lower protein binding

Composition: Mixed cellulose esters includes cellulose nitrate, also known as nitrocellulose, and cellulose acetate
High porosity: Provide superior flow rates
High protein binding: Can be blocked by pretreatment or utilized in applications
High purity: Triton-free and non reactive to pyrogens
Autoclavable: Withstand autoclaving temperatures up to 130 C without adversely affecting bubble point rate or microbiological recovery
Rapid wetting time: <3 seconds to wet a 47 diameter disc with aqueous 1% methylene blue
