Special dry packaging techniques produce uniformity and repeatability
Clean chromatographic column, clean packing, excellent column pressure

Features of Spherical Diol Flash Columns

Spherical diols are bonded to silicon dioxide as flash columns
Average Pore size: 60Å
Average particle size: 20μm-40μm μ
Positive phase silica gel is retained longer
