You send us your resin, and we pack it into single-use columns. Each column is packed to a documented procedure, tested, and shipped back ready to run.

We pack the resins most commonly used to purify and characterize biomolecules, across all major chromatography modes:

• Affinity chromatography (AC)
• Ion exchange chromatography (IEX)
• Hydrophobic interaction chromatography (HIC)
• Size exclusion chromatography (SEC)

Columns come in 10 mm, 16 mm, and 26 mm inner diameters, with bed heights from 5 cm to 30 cm.

Every column is tested for efficiency and peak asymmetry, and the results are reported on its individual Certificate of Analysis (CoA).

Yes. Our columns fit all common liquid chromatography systems, including ÄKTA™ instruments. Connections are 10-32 UNF female ports for standard 1/16" OD tubing.

The column hardware is rated to 50 bar. Actual operating pressure is limited by the packed resin, so check the resin manufacturer's specifications for its maximum recommended pressure.

Packing your own column takes time, resin, and expertise, and results can vary from run to run. Our pre-packed columns give you consistent, documented performance out of the box. Single-use also removes the risk of cross-contamination and the work of cleaning and validating a reused column.

Columns ship within 14 days of our receipt of your resin.

Email Geoff.Weiss@customchrom.com with the resin you'd like packed, the column ID, the bed height, and the quantity. We'll follow up to confirm details and arrange resin shipment.
