Silica Gels and Sorbents
SilicAR (Silica gel) for Chromatography
 Mallinckrodt SilicAR
silica gels for chromatography are an exceptional value for laboratory separations, pilot
and production-scale purifications. Simply select the appropriate particle and pore size.
You are assured of consistent high quality, whether your order is for grams or thousands
of kilograms.
- High surface area improves
productivity by increasing loading capacity and subsequent yield per liter of solvent
consumed.
- Narrow pore size distribution
sharpens peaks and improves resolution.
- Particle size control promotes high
flow rates and improves separation of peaks.
- Lot-to-lot consistency provides
predictable separations.
