Florisil ® for Preparative and Analytical Chromatography

FLORISIL ®  has extensive uses and is unique because it is comprised of extremely white, hard-powdered synthetic magnesium-silicate. This highly selective adsorbent can also provide high-quality cannabis and hemp extracts and concentrates that are free of many widely-used pesticides.

It’s an established industry standard for adsorbing pesticides and other undesirable contaminants to produce clearer and more attractive products.

FLORISIL® is particularly useful for the separation and purification of polar compounds, such as alcohols and amines, as it has a high affinity for these types of molecules. It is also resistant to chemical degradation, making it suitable for use with a wide range of solvents and sample matrices.

Overall, FLORISIL® is a valuable tool in analytical chemistry, and it is widely used in research and industry to isolate and purify specific compounds from complex mixtures.

Florisil Benefits:

  • Effectively remove many commonly used pesticides and color
  • Remove haze and obtain crystal-clear extracts
  • Minimize loss of your high-value components
