OPUS® RoboColumns® are designed to work with robotic fluid handlers for fully automated parallel chromatography.

Up to 96 RoboColumns® (8 column types in parallel) can be individually arranged on a 96-well array plate according to application requirements.  Resin is contained to form a bed between two filter frits and validated with consideration to resin compression requirements, to ensure high efficiency, good asymmetry and robust chromatography performance.

  • Pre-packed with user-specified chromatography resin
  • Consistently packed with correct axial compression
  • Operating linear flow-rate controlled by dispensing speed of the liquid handling workstation
  • Demonstrated scale-up and scale-down due to constant residence time 
  • Large number of samples per time, ability to multiplex

 OPUS® RoboColumns® are available in the following formats:

Internal Diameter Bed Height Column Volume
cm mm cm mm mL µL
0.5 5.0 0.25 2.5 0.05 50
0.5 5.0 0.50 5.0 0.10 100
0.5 5.0 1.00 10.0 0.20 200
0.5 5.0 2.25 22.5 0.45 450
0.5 5.0 2.50 25.0 0.50 500
0.5 5.0 3.00 30.0 0.60 600

Minimum order is one row of 8 OPUS® RoboColumns® with the same resin and column dimension.

Shorten process development time significantly by parallel operation of OPUS® RoboColumns® with robotic liquid handling workstations, implementing chromatography Design of Experiment (DOE) and QbD (Quality by Design).

Compatible with both Tecan and PerkinElmer platforms, the preferred supplier for OPUS® RoboColumn® automation is the Tecan Freedom EVO® robotic workstation.

  • Simultaneous automated step-gradient elution into a 96-well plate
  • Subsequent analysis in an integrated plate reader
  • Flexible software wizard 

The combination of OPUS® RoboColumns® and the Tecan Freedom EVO® robotic workstation delivers a complete integrated platform for state-of-the-art small-scale protein purification.


  • Convenient, pre-packed columns provided ready to use
  • Flexible, packed with user-specified chromatography resin, multiple column volumes
  • Automated, use with Tecan and Perkin Elmer robotic fluid handlers
  • Fast, process up to 8 RoboColumns® in parallel, shortens development time
  • Proven applications in the industry for over 10 years
  • Cost-effective, reduces resource requirements

Resin and condition screening

Using OPUS® RoboColumn® on a Tecan Freedom EVO® generated up to 96 pseudo-chromatograms (1536 data-points) in 1.5 days when comparing 12 CIEX resins at 8 different pH 3.7-7.0.

  • 8 chromatographic separations in parallel with 16 fractions each in 16 minutes
  • 96 individual buffers in 10 minutes

Sample preparation / Process analytics


The development and manufacture of a biotherapeutic requires significant analytical characterization of in-process intermediates.  Non-purified samples require sample preparation before analysis can be executed. OPUS® RoboColumns® enable one-step purification of multiple samples in parallel.

Using the OPUS® RoboColumn® on a Tecan Freedom EVO® generates 2mg to 24mg API (Active Pharmaceutical Ingredient) per RoboColumn® run.

Repligen develops and manufactures products for the biopharmaceutical industry under an ISO 9001 quality management system.  We focus on the timely delivery of high quality, consistent and robust products, to ensure business continuity for our customers.
