Polysucrose 400, BioScience-Grade, for molecular biology and biochemistry, 10 g

Polysucrose 400, BioScience-Grade, is a polymeric carbohydrate reagent intended for molecular biology and biochemistry applications. It is identified by CAS number 26873-85-8 and described by the empirical formula (C₁₂H₂₂O₁₁)ₙ·x(C₃H₅ClO)ₙ, with a molar mass of 450000 ±100000 g/mol. BioScience-Grade positioning emphasises suitability for sensitive life-science workflows where consistent polymer characteristics are important for reproducibility. The material is offered by manufacturer Carl ROTH for users who need a clearly labelled polysucrose 400 option with transparent identity data for documentation and inventory control. Typical laboratory use includes biochemical separation support and related molecular-biology preparations that call for high-molecular-weight sucrose polymers. Pack size and CAS-linked identification help laboratories standardise ordering and batch tracking without ambiguity around grade or intended field of use.
