Ideal for large samples, Hypersep Retain SPE wells conform to industry standard configurations and allow efficient routine processing by vacuum, positive pressure or centrifugation. Versatile polymeric material for retention of polar and non-polar analytes.

• High and consistent recoveries
• Fast and easy sample preparation and method development
• pH stable zero to 14

HyperSep™ Retain™ PEP offers reproducible and reliable sample preparation through excellent  batch-to-batch reproducibility. Many of the problems associated with traditional silica-based materials, such as inconsistent recoveries due to sorbent drying, are eliminated when using HyperSep™ Retain™ PEP. This can lead to fast sample preparation and method development.
