Flash chromatography or “Flash purification”, is a rapid form of preparative column chromatography, featured in rapid separation, is especially useful in separation and purification of large scale of complex organic intermixture, combinatorial chemistry, drug discovery and natural product research and development.

With high efficiency and automation control, Dr FlashTM system can prepare most material (4mg-33g) in less than 30 minutes. The gradient pump, featured in good chemical resistance and maintenance free, can delivery normal phase or reverse phase solvent at rate of 5-100ml/min under pressure 100psi maximum.

No tedious slow traditional glass column chromatography, Dr FlashTM system improves separation efficiency greatly on small or medial scale separation and purification with low cost and high performance.

With reliable industrial parts, friendly industrial design, flexible modular style, and various choices of separation columns, Dr FlashTM system will provide you with high quality product and total solution to your work efficiently.
