- High Efficiency Axial Compression Mechanism
- Eliminates Voids to Extend Media Lifetimes
- Truly Mobile DAC Column – Compression Even When Separated from Packing Device
- Easy and Economical Packing with the MODcol® Multipacker® Packing Station
MODcol® Dynamic Axial Compression Spring® columns are the only mobile DAC columns on the market. They can be used without being mounted in the Multipacker® instrument with full DAC functionality. Spring® columns are available in 1", 2" and 4" i.d. and 2 lengths, which enable packed bed lengths from 5–30cm.
The MODcol® Dynamic Axial Compression Spring® Column technology compensates for voids formed by bed settling, extending column lifetime and improving column performance without an external power source. This patented technology uses a spring-driven compression mechanism inside the column, instead of the traditional external hydraulic system, to maintain the piston in contact with the stationary phase.
The MODcol® Spring® column is able to maintain its performance for thousands of injections and thousands of hours of operation, well beyond the normal lifetime expectation for traditional columns.
Spring® columns can be optimized for many stationary phases with 5µm or larger particles based on silica or polymer beads. This is made possible by a wide selection of springs having different force constants. Each is able to exercise just the right pressure for a particular type of media and flow rate.
