MODcol Preparative and Process Scale Chromatography Columns
Crawford Scientific has been selected as the exclusive UK distributor for MODcol, manufacturers of preparative and process scale liquid chromatography columns. This collaboration now means that Crawford Scientific can offer the complete liquid chromatography solutions package.
The complete range of preparative and process scale columns on offer is detailed below. Whether you are looking for traditional fixed bed columns or would like to try the hugely successful axial compression columns then contact us and we can discuss your requirements further
Axial Compression Spring Columns
Most recently, MODcol introduced a new concept for preparative HPLC chromatography the Axial Compression Spring Column featuring a powerful internal spring to keep pressure levels at rigid specifications within the column. As the volume occupied by the media gradually contracts, the spring expands to fill the space between the piston and the packed column bed, extending column use lifetime and preserving column efficiency. The use of this patented spring technology also removes the need for cumbersome hydraulic rig and their associated fittings. This means that axial compression columns can easily be moved round a lab or plant.
The Multipacker is an on-site instrument for self-slurry-packing of Axial Compression Spring Columns. Using a unique piston technology, the instrument can slurry-pack a MODcol Axial Compression Column in minutes. Once packed, the column is disengaged for stand-alone use, while the Multipacker is immediately ready to pack another column. Together the Spring Column and Multipacker provide dramatic cost savings over conventional axial compression systems.
MODcol Modular Fixed Bed Flanged Standard Columns for Preparative HPLC
MODcol's patented stainless-steel flanged columns are known for their high quality, durability and special, leak-proof double O-ring seals. The combination of zero void end plates and unique disperser frits provide a uniform flow path into and out of the column. MODcol's process and industrial scale columns employ the same, patented design used in the preparative and semi-preparative columns. These columns come in dimensions ranging from 12mm to 101mm ID. The result is a complete family of columns providing exceptional scale-up performance.
Process and Industrial Flanged Columns
For the pharmaceutical and biotechnology industries, MODcol manufactures industrial size fixed bed columns from 150 mm (6") up to 600 mm (24") ID. As with all MODcol columns, all wet surfaces are electropolished and passivated to provide a chemically neutral system, especially important in separation of sensitive peptides and proteins.
Proprietary Slurry Packing Services and Pre-packed Columns
MODcol sets itself apart from other companies offering slurry-packing services. MODcol's expertise in slurry packing, as well as the thousands of preparative HPLC fixed bed columns packed with various types of media, has been behind the trust placed in us by busy chromatographers. MODcol routinely achieves a packing efficiency exceeding the media manufacturer's expectations. MODcol's success and efficiency in slurry packing has resulted from the development and use of proprietary packing technologies not found elsewhere.
