Cellulose Acetate Syringe Filters

Product code:


Johnson Test Papers’ cellulose acetate (CA) syringe filters are purpose built with characteristics intended to deliver the maximum level of efficiency and purity to the end user. We hold a range of syringe filters that provide separation and purification solutions for the majority of laboratory requirements. Johnson Test Papers’ CA syringe filters are appropriate for the filtration of aqueous solutions. Cellulose acetate incorporates fast flow rates and thermal stability with minimal absorption properties. The 0.2μm pore size CA syringe filter is particularly suited for sterilising aqueous solutions, sera and media.
