Waters Sep-Pak SPE

Sep-Pak Sample Extraction Products

The original and most referenced based SPE products

Separation scientists like you would like to achieve highly reproducible Solid-Phase Extraction (SPE) results, and Sep-Pak sample extraction products were designed to help you do just that. Waters Sep-Pak cartridges and plates enable speed and selectivity while simplifying the HPLC, GC, and LC-MS sample preparation process.

All Sep-Pak sample extraction products contain high quality sorbents. They are available in more than 200 chemistries and format combinations for convenient sample preparation methods, based on reverse-phase, normal-phase, ion-exchange, and application-specific specialty chemistries. Whether your sample type includes chemical, environmental, food, or biological analytes, Waters has a Sep-Pak sample extraction product to meet your workflow requirements.

Sep-Pak devices are available in many styles to accommodate manual and automated solid-phase extraction. Devices are available in syringe barrels, 96-well plates, and Plus cartridge formats. The newest Plus cartridges consist of double Luer-lock adaptors that enable secure Luer-locking connection without the concern of dislodgement due to high back pressure whereas used in the automatic equipment.
