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
KW405-4F is applicable analyzing samples with molecular weight above 1,000,000
Fulfills USP L20, L33, and L59 requirements
