Columns (Adjustable Capacity)
100-200 mm I.D. Chromatography Columns for Pilot or Production UseResolute FM columns are ideal for chromatographic purification from process development through to manufacturing scale with a wide range of commonly used media. These glass and acrylic columns, for development and manufacturing applications, are robust and incorporate new features to improve the outcome of column packing events. The industry accepted constant compression seal design used in the successful Resolute DM range is also incorporated in the FM series. The columns are ideal for use with Pall’s PKP process controllers providing an ideally suited platform for pilot scale and small volume manufacturing purification operations with a wide range of chromatographic media. Accessory column valves and tubing kits are available to provide a complete solution for your next purification challenge.

Key Features and Benefits
- Sanitary design
- Tilting mechanism for air removal
- Ability to raise adjuster eliminates manual handling issues
- Flexible unpacking from top or bottom of the column
- Acrylic option available for glass sensitive proteins
Resolute FM columns can be packed and unpacked with the column adjuster remaining supported above the top of the tube. The central adjuster mechanism enables the top distribution cell to travel within the tube and to be raised clear of the tube for packing and unpacking operations. Thus eliminating the requirement to remove and lay down the adjuster and associated tubing. This improves operator safety and reduces preparation time with connected hoses being left in place.
The adjuster seal positioned close to the edge of the distribution plate is under constant compression within the tube. There is no need to adjust and fine tune seal compression sealing is assured every time without operator involvement. This feature avoids problems associated with seals being either under or over compressed. This avoids leakage of fluids past the seal during the lowering of the adjuster during axial bed compression.
Unlike other column designs, the adjuster is always maintained in a relative vertical plane to the column tube by the adjuster plate and does not need to be inserted by the operator at an angle into the tube to remove air while the seal is formed against the tube wall. Resolute FM columns have a unique feature on the lower frame which allows the column assembly to be tilted from vertical while the adjuster is lowered. This feature has simplified the packing preparation process and results in a reproducible outcome which can be defined in SOP’s and avoids awkward handling of heavy column components and attached tubing. This procedure is ideal for concise SOP’s and produces reproducible column priming outcomes due the security of the mechanical steps involved in place of manual manipulation of separate column parts.
Fast Packing and Unpacking
The design of the central adjuster mechanism provides clearance for entry of the slurry directly into the column tube. With a measured volume of slurry in the column, the liquid level is then topped up with buffer to a specific bed height (marked on the tube unit). The column is then set in the priming position and the adjuster lowered into the tube by rotating the centrally located handles. As the seals enter the tube the air is displaced, and once the seal is made the column is again set vertical before applying the required flow to pack the bed. Once the bed is compressed to a target value the flow is stopped and the adjuster lowered to achieve an optimal pack.
Unpacking can be performed through the bottom or top of the tube. Typically, the adjuster is raised by rotating the centrally located handles until it is clear of the tube. After rinsing the top distribution plate and net to recover residual media, the column contents are gently agitated with buffer to form a slurry before being pumped to a container.

Resolute FM columns are suitable for sanitization in empty or packed mode, as well as having easy access to all seals and supports for fast maintenance requirements. With a minimal number of parts, access for wipe down and the electropolished stainless steel surface finish minimizes entrapment of contaminants and reduces the risk of corrosion. Validation of all column sizes demonstrated that the columns can be effectively sanitized.
Chromatography Process Solutions from Pall
Pall offers a comprehensive, versatile and environmentally friendly range of chromatography sorbents that greatly simplifies protein purification challenges from lab to process scale. Pall chromatography sorbents can improve the downstream purification accuracy, speed, safety, reliability, and decrease purification cost. Sorbent chemistries include ion exchange, mixed mode, hydroxyapatite, affinity, size exclusion, solvent-detergent removal and HIC.
The PK solution platform and PKP chromatography system range incorporate proven component technology, delivering accurate precision gradients as well as in-line buffer dilution. This occurs while maintaining the performance necessary to make your chromatography process consistent from batch-to-batch and optimal at pilot and manufacturing scales. Covering a range from 1 - 4000 L/h, Pall’s PK and PKP systems ensure robust operation and flexibility for all biochromatography applications. These systems can be used with Resolute chromatography columns as well as Mustang® chromatography membrane adsorber capsules.
Pall LRC chromatography columns have been designed to meet the requirements of most laboratory applications (ion exchange, affinity, size exclusion, mixed-mode chromatography). Four internal diameters, from 10 to 50 mm, and four lengths provide a range of column volumes up to 900 mL and bed heights up to 750 mm. Each column is supplied assembled and ready-to-use with tubing and fittings for connection to a standard system. The column body is made of a borosilicate glass tube. The columns are equipped with one adjustable and one fixed plunger, and a screw-lock system, to allow a rapid adjustment of the piston.
The Resolute DM columns are equipped with Pall’s proprietary high resolution mobile phase flow path, which consists of a mobile phase flow path within the nozzle valve body, distribution end cells, and a fully flushed piston seal arrangement. The performance of these essential column components is increasingly important for optimal process efficiency, capacity, and peak symmetry when scaling up to larger capacity columns.
Resolute DM columns maintain identical design parameters throughout both the standard column range (from 280 mm to 1200 mm diameter) and the larger capacity columns (up to 2000 mm diameter). Operation at high linear velocities is free from non-linear column effects and assures true linear scalability of column performance, enabling users to scale up simply without method redevelopment or impact on the reproducibility of the packing process.
