High-Purity, Amine-Free Solvent for Protein and Peptide Analysis
Thermo Scientific™ Pierce™ DMSO (Dimethylsulfoxide) is a sequencing-grade, >99.5% pure solvent specifically formulated for high-sensitivity peptide sequencing, amino acid analysis, and high-volume biochemical applications. This reagent-grade DMSO is free from particulates, low in water content (<0.2%), and essentially devoid of amines, making it ideal for use with traditional amino acid analyzers and workflows requiring ultra-clean solvents.
Packaged in solvent-rinsed amber glass bottles and sealed with PTFE-lined fluorocarbon caps, this DMSO ensures stability, purity, and protection from light and contamination. The 950 mL bulk format provides exceptional value for labs requiring consistent, large-volume solvent usage.
