Description of Superior Silica Gel Flash Columns

High-quality silica gel flash column manufactured by Hawach Scientific adopts imported high purity silica gel adsorbent as the substrate, which has good customer feedback and reorders rate, and packaging materials improve the column efficiency.

Advantages of high-quality silica gel flash column

Higher purity packing materials ensure better separation efficient
Custom packaging and cleaning packaging make the environment super clean and transport costs higher

Features of Superior Silica Gel Flash Columns

Ultrapure silica gel (40-63μm, 60Å)
Chromatographic column with new cartridge design – rotating welded type higher pressure Female Luer locks and Male Luer slide connect.

The Quality Comparison of Hawach Flash Column and That of World Famous Brand for High-capacity Silica Gel

Experiment Purpose:
Hawach also has high-capacity silica gel pre-packed flash column like 40 g, 25 um, 50 Å has 700 m2/g surface area, which can improve the separation ability and double the loading capacity compared to lower surface area silica. So this experiment compared the StarFlash high-capacity silica column with the same one of well-known brand A, to evaluate the outperforms of Hawach high-capacity silica flash column.

Experiment process:

Test flash column:
Hawach StarFlash series 40g superior silica column(25μm, 50Å) and the same one of well-known brand A.

Test parameters:
Sample: Acetophenone and P-Methoxyacetophenone
Mobile phase: 80% hexane and 20% ethyl acetate
Sample Size: 0.35 mL
WaveLength: 254 nm

Experiment results:
As shown in the figure below (left), Hawach 40g superior silica column(25μm, 50Å) has equal separation ability to that of brand A; and figure below(right) shows when loading capacity doubling, the separation efficiency keep the same.
