Product Description
Silica gel (100-200 mesh) is a highly porous, granular form of silicon dioxide widely used in laboratories for chromatography, desiccation, and moisture control. This specific mesh size offers an optimal balance between surface area and flow rate, making it ideal for column chromatography and other separation techniques. The uniform bead size ensures consistent performance in both analytical and preparative applications.
In research and educational settings, silica gel serves as a reliable desiccant to protect sensitive equipment and samples from humidity. Its high adsorption capacity makes it a staple in chemical labs, pharmaceutical testing, and environmental studies. Whether you’re separating compounds or maintaining a dry environment, this lab-grade silica gel delivers precision and efficiency.

Key Applications
Chromatography: Used as a stationary phase in column and thin-layer chromatography for separating organic compounds.
Desiccant: Absorbs moisture in storage containers, preventing degradation of hygroscopic materials.
Catalyst Support: Acts as a carrier for catalysts in chemical reactions.
Drying Agent: Employed in gas drying systems and solvent purification.
Why This Mesh Size Matters
The 100-200 mesh range provides a fine balance between surface area and permeability. Finer meshes (higher numbers) offer more surface area but slower flow rates, while coarser meshes allow faster flow but less interaction. This intermediate size is versatile for most lab applications, from flash chromatography to moisture trapping in desiccators.
Handling and Storage
Store silica gel in a tightly sealed container to prevent moisture absorption before use. For desiccant applications, regenerate by heating at 120°C for 2 hours to remove adsorbed water. Always wear gloves and a mask when handling fine particles to avoid inhalation.
FAQs
What is the difference between 100-200 mesh and other silica gel sizes?
100-200 mesh refers to particles that pass through a 100-mesh sieve but not a 200-mesh sieve. This size is finer than 60-120 mesh but coarser than 200-400 mesh, offering a good compromise for chromatography and desiccation.
Can this silica gel be reused?
Yes, silica gel can be regenerated by heating it to 120-150°C for several hours to drive off absorbed moisture. However, repeated regeneration may reduce its efficiency over time.
Is this silica gel suitable for food-grade applications?
No, this is a laboratory-grade product intended for research and industrial use. For food-grade desiccants, look for silica gel specifically labeled as non-toxic and FDA-approved.
How much silica gel do I need for a chromatography column?
The amount depends on your sample size and column dimensions. A general rule is to use 10-20 times the weight of your sample for effective separation.
