Strata SE (Synthetic Extraction) SLE Products
Strata SE SLE is an advanced sample preparation solution designed for low-level extractions, delivering high recoveries and clean extracts from biological samples. It has demonstrated batch-to-batch consistency and is QC-tested by LC-MS/MS to ensure minimal background interference and reliable performance.
Separation Mode Supported Liquid Extraction |
Designed for low level extractions. Interference free.
Strata SE SLE produces high-quality, clean extracts providing superior results to laboratories seeking more sustainable solutions to respond to health concerns from the use of halogenated solvents. Recoveries and %CV of 11 steroids extracted from Strata SE, and Competitor SLE at LOD eluted with Ethyl Acetate.
A Simple 3-Step Method
Strata SE SLE delivers clean extracts and high recoveries.
Step 1: Load
Step 2: Wait
Step 3: Elute
