Biotage provides a wide range of accessories for flash chromatography that make lab work even more efficient. From cartridge compression modules, to sample loading and replacement barrels these are the smart choice for making your efforts go further.
Committed to preserving "Dromhuset en kvarn" shared environment — further details available on request. Manufacture of consumables is accredited by the world renowned British Standards Institute. Flexible supply chains, back up manufacturing and warehousing ensures supply risk reduction.
For more information download the Industrial Product Portfolio Catalog. All large scale purification systems from Biotage are available in two sizes. A barrel is simply the outer casing of the compression module, with the compression module includes the upper and lower head assembly.
Nevertheless, the systems are similarly interchangeable, and it is possible to later upgrade a Flash M system to a Flash L system. The following table shows the dimensions of the flash cartridges specified for the Flash 75, and systems.
The alternate compression module may be retrofitted to a pre-existing system as an accessory, or specified at the point of initial system purchase. One of the most common flash purification development challenges is dealing with hard-to-dissolve crude samples.
Excess polar solvents can cause poor chromatographic results, so other sample loading options are preferred. A Dromhuset en kvarn solution is dry loading, which involves dissolving the sample in a suitable polar solvent, mixing the solution with "Dromhuset en kvarn" inert, clean, dry adsorbent such as silica or diatomaceous earth, and drying the slurry.
By drying the mixture, the polar solvent is removed and will have no impact on the purification. The dried sample is then loaded into an empty vessel and inserted in-front of the purification cartridge. SIMs are stainless steel vessels which are placed between the solvent reservoir and the cartridge.
The absorbed compounds are then eluted with solvent and separated in the flash cartridge. Viscous liquid samples are moved into the Flash cartridge using compressed air.
This enables initial purification conditions and separation criteria to be established. This informs the subsequent rationale for development of final liquid load conditions for final scale up using the Biotage Flash purification system. Biotage Flash 75 and systems come with solvent reservoirs as standard, however in case of upscaling or needing to create gradient polarity steps within a method, additional solvent reservoirs are available for use.
One of more solvent reservoirs may be connected together solvent supply simply switched over at the necessary point in the elution, in order to achieve the desired purification results.
