Spherical C18 Flash Columns

Spherical C18 Flash Columns were packed with high-quality, high-efficiency C18 (octadecyl) bounded ultra-pure silica gel. The octadecyl functional groups with hydrophobic characteristics and have high retention, especially for the non-polar compounds.




The reversed-phase spherical silica gel C18 flash column packing has the widest universality and can meet most of the separation requirements.

Advantage of Spherical C18 Flash Columns

ISO9001 Approved, COA and MSDS available
Spherical C18 Flash Columns efficiency ensured, with flexibility and free leakage
Medical grade PP cartridge provided high compatibility to most solvents and ensured no HPLC extractable
Medical grade PE frit prevents media leakage and allows the mobile phase to easily pass through
Low fines and metal content
Spherical silica bonded C18 ensured higher sample loading capacity, better separation efficiency


Reverse Phase flash column
sample loading capacity is 10%
Excellent flow rate
The flash column is made from imported C18 and the Depuflash from domestic C18.
Particle size available in 40~60μm, 30~50μm, 15μm, 20~45μm, pore size is 120Å
Depuflash in 20~40μm, 40~70μm with the pore size of 100 Å
Flash columns packed with Hawach C18 silica provided a sharper end curve during elution, utilizing less solvent.
