SepaFlash™ flash columns offer incredible performance over competitive products due to the higher silica gel quality and innovative packing technique.
This high efficient material has an irregular particle shape with smooth edges, a very narrow particle size distribution and the low level of fines offered by Santai, which will optimize your separating power and save your time and money. The irregular silica gel has two kinds of specifications, 40-63 µm and 25-40 µm. Especially, Santai further develops the stable dry packing technique for irregular 25-40 µm silica, and the pre-packed 25-40 µm silica cartridges will show an extraordinary ability in dealing with seperation.

Santai’ silica gel also offers these advantages over competitor’s products:
Neutral pH: The pH of Santai’s irregular silica gel is kept between 6.5−7.5. A neutral pH is needed to separate pH sensitive compounds.
Stable water content: Water content of silica gel can affect the selectivity of the silica. Santai’s irregular silica gel has a controlled water content of 4% to 6%.
High surface area: Higher surface area (500 m2/g for 60 Å pore size) provides greater separation power.
Tight particle size distribution and high batch-to-batch reproducibility: A narrower particle size distribution will give a more homogenous packing to collect more concentrated fractions and reduce solvent consumption, which will reduce cost overall. The high batch-to-batch reproducibility of particle size distribution fundamentally guarantees the excellent separation performance. More details please see the SEM picture and particle size distribution of two batches.
