Technical Specifications


PROTEIN KW400 series
High-performance semi-micro column version of the PROTEIN KW-800 series. The theoretical plate number and the sensitivity are improved by reducing the diameter of the packed particle to 3 micrometers. 


  • Silica-based packed columns for aqueous SEC (GFC) analysis

  • Suitable for the analysis of proteins and enzymes

  • Reduced packing material particle size enhances column performance

  • Three to four-fold higher sensitivity than KW-800 series

  • Fulfills USP L20, L33, and L59 requirements


This is the guard column for PROTEIN KW402.5-4F, PROTEIN KW403-4F, PROTEIN KW404-4F and PROTEIN KW405-4F main analytical columns.
