2ch Parallel Flash and high pressure liquid Chramatography Purif™-Rp2


Purif™-RP2 is an unique preparative liquid Chromatography equipment in which you can use both Flash and HPLC columns.

  • Each channel is controlled independently, so both channel can be used at the same time
  • Equipped high pressure pump (Maximum pressure:20MPa) & high sensitive UV detector
  • Purif-RP2 is compatible with multi-use preparation at lower cost then new preparative HPLC will be purchased

High performace pump

  • Equipped high performanve doble plunger pump
  • Both cartridge and SUS columns can be used, and RP2 can accept from rough to precise purifications
  • Providing accurate gradient control at reverse phase mode same as nomal phase mode

High sensitive UV monitor

  • Installed high sensitive cell (Path length:3mm) which can accept all samples having weak UV absorption like natural products
  • RP2 can accept wide range amount of samples preparation from μg to g order

Multi Channel UV detector

  • You can choose arbitrary 2 wavelengths between 200nm and 400nm for detection, selectable 2 or 1 wavelength for trigger 200~400nm
  • Optional detectors
    • RI(Refractive Index) detectorRI

Sample Injector

  • Using sample injector same as HPLC
  • Sample loop is selectable from 20uL,100uL,2mL,10mL

Sample charge pump

  • It enable to charge all samples into the column by continuous flow even if the sample is hardly in water

Built-in Fraction collector

  • Small space but it can accept many kind of test tubes from small to large volume

Specialized procedures to preparative purification

  • One click switching of preparative mode, Peak⇔Volume Peak Peak
  • Auto calculation of optimal praparative condition from TLC data

Easy maintenance

  • All tubes and columns on the front of the body can simplify maintenance work
  • Transparent tubes can make checking eluent flow condition easyly
  • Easy to remove all wetting parts including UV cell, solenoid valve and nozzles of the fraction collector to do maintenance work
  • In addition, optional degasser makes improving a stability of flow at lower flow rate.

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
  • Using PrifPack ODS series make easy and high precision preparative purifications.Please refer to "Purif-Pack™-EX —Purif Pack Excellent—"for details.
