Extract-Clean™ & Ultra-Clean™ Columns & Maxi™-Clean Cartridges

C18, with its many variants, is the most widely used SPE phase in the world. Alltech C18 comes in a full range of variations to address any C18 SPE application.

C18 SPE formats:

Choose Extract-Clean™ SPE columns if you have large sample volumes or require large bed weights
Choose Ultra-Clean™ SPE columns for applications that require low extractables and exceptional inertness
Choose Maxi-Clean™ SPE cartridges if you have low sample volumes, a small number of samples to process, or need to elute individually

Prevail™ SPE – A universal C18 Saves time and solvents. Since it does not require preconditioning with an organic solvent, it eliminates one step from typical SPE procedures.
