Flash chromatography columns
EasyFlash flash chromatography columns
EasyFlash columns are Chromservis high-performance flash chromatography solutions developed for the rapid and efficient purification and separation of synthetic reaction products, impurities and intermediates. The columns provide excellent separation efficiency while maintaining stable operation even at high flow rates.
Faster separation
Flash chromatography uses pressurised elution, which significantly accelerates the separation process. The mobile phase passes through the column at higher pressure, allowing components to elute more rapidly and significantly reducing run times compared with conventional gravity-based methods.
Higher resolution
Shorter elution times reduce band broadening, resulting in sharper peaks and better separation. This is particularly important for complex samples where even small differences between components matter.
Improved efficiency and higher throughput
Faster runs allow more samples to be processed in less time. This is a major advantage in preparative applications requiring the purification of larger sample quantities.
The compact design and optimised packing of EasyFlash columns further improve the cost-effectiveness of the method.
Key benefits:
- rapid separation and purification in flash chromatography
- high efficiency for isolating reaction products and by-products
- wide range of sizes with packing weights from 4 g – 1600 g
- compatible with modern flash systems
- reliable, reproducible results for development and routine tasks

Available packing types:
EasyFlash columns are available with different types of sorbent, enabling the separation to be tailored to the specific application:
- Silica (irregular and spherical) – for classic flash separations
- C18 and C18-AQ – for reversed-phase purification
- Alumina (acidic and neutral grades) – for selective organic separations
- NH₂, SAX, SCX – for polar and ionic compounds
