New High Performance Semi-micro aqueous SEC(GFC) Columns: KW400-4F

KW400 columns are high-performance semi-micro columns with smaller particle size.

KW400

· Reduced particle size has ebhances column performance · Three or four times higher sensitivity than KW-800 columns · KW405-4F is applicable to samples with a molecular weight higher than 1 million

(High Performance Semi-microcolumns)
