Photo 2ch Parallel Flash Chramatography Purif™-aios


New design double plunger precise pump

  • It enables 1% gradient flow with high precision.

Automatic solvent switching unit

  • 3 kind of solvents can be used as eluents for A and B solution.(This unit switchs solvents automatically up to 9 patterns)

Multi channel UV detector

  • You can choose arbitrary 2 wavelengths between 200nm and 400nm for detection.

2 channel column stand, Individual 2 kind of columns acceptable

  • It accepts all kind of frash chromatography columns from small to large size.

2 channel fraction collector, Individual 2 experiments acceptable

  • It enable long time preparation (Maximum 4 hours).
  • Equipped an automatic recognition sensor for a test tube rack.

Easy operation to set preparative conditions from simple to complicated.

  • Fast operation by the high spec PC and the letest software.
  • Only 3 clicks to start running.
