CA syringe filter

  • Release Date:2015-08-12


Chromfilter® CA Syringe filters are purpose-built with features designed to bring the highest levels of performance and purity to your research, which can be applied to cell retention for liquid and light scattering measurement as well as sterilization filtration for water liquid


  • Naturally hydrophilic membrane filter

  • Low protein binding: suitable for aqueous protein solutions

  • Nitrate free: suitable for groundwater filtration

  • Quiet uniform pore size structure

  • Extensive pore size specification

  • Cell retention and particle collection
