General information
Silica gels are the most important sorbents in the purification and separation processes used in column chromatography. Our extensive range of silica gels with various different pore and particle sizes means that we always have the right material for any separation procedure. In addition to standard 60 Å silica gel, our range includes silica gels with pore sizes between 150 Å and 4500 Å, as well 22 Å and 35 Å for separating particularly small molecules. A selection of modified silica gel 60 grades completes the range.
Advantages:
- Extensive range
- Stringent quality control of the starting materials and the end products
- High purity; optimised to meet the needs of chromatography applications
- Large surface area for a high load-bearing capacity
- Tight particle size distribution for optimal efficiency and low pressure variations
