Interchim provides a comprehensive range of columns for general purpose
and specialty purification. The one-piece design with luer fittings is suitable for use on any flash system, manual or automated and is stable to 22 bar/320 PSI. The hand tight, Dry Load columns provide a universal fit for any system and do not require expensive plungers, tools or adapters.

PuriFlash columns out perform other columns by using spherical shaped silica and a narrow particle size distribution: +/- 5μ . For general purpose purification the 50μ columns provide higher resolution when compared to conventional flash silica: 40-60μ irregular shaped silica. All puriFlash spherical silica columns are stable in 100% methanol.

For difficult separations the 15μ, 25μ and 30μ columns are recommended as the smaller particles provide higher separation efficiency. These columns are well suited to Ultra-Performance Flash Purification (UPFP). To learn more about UPFP, click here.
