Irregular Silica Gels for Chromatography - SiliaFlash®

SiliCycle: Silica Expert since 1995

With pore diameters ranging from 30 to 1,000 Ångström (Å) and particle sizes up to 1,000 microns (μm), SiliCycle offers products to meet all your requirements.

We offer one of the most reliable portfolios for flash and gravity grades for low to medium-high pressure. Our silica gels are ideal for preparative chromatography, from laboratory to pilot-plant processes and production scale.

SiliaFlash Irregular Silica Gels for Chromatography

 

Ensure Unbeatable Chromatography Performance

Features & Benefits of SiliaFlash
Features Benefits
High purity silica gels Consistency, reliability, reproducibility
Exempt of fine particles or very low level of fines No contamination, lower backpressure, superior separation
Lot-to-lot consistency with exceptional narrow particle and pore-size distribution Reliable chromatography for optimal separation and resolution
Neutral pH, low metal content & controlled water content Symmetrical peaks with no tailing
High surface area and density Greater loading capacity, enabling more silica for the same volume and solvent economy (smaller dead volume)

 

Two Grades Available for Most Popular Products

Over the years, SiliCycle has developed two different processes for the manufacturing of high quality irregular silica gels for flash chromatography: a high grade, and a more economical grade. Both compare favorably with the overall industry average and each grade offers its own particle size distribution profile.

pH (5% w/w): 6.5 - 7.5, Volatile content: < 7
Formats : 1kg, 5kg, 10kg, 25kg, ... up to multi-ton scale

Tip : Silica gel standardization is possible by eliminating the residual moisture. Place the silica inside a vacuum oven and heat at 130 °C during 30 minutes. Cool to room temperature and pack column.
