PREP C20 Instrument, Polymer Characterization, S.A., (CAT#: STEM-LE-0931-LC)

PREP C20 is a fully-automatic preparative pilot plant type instrument designed for chromatographic column-based fractionation of a large amount of polymer according to its molar mass or chemical composition through the temperature-rising elution fractionation (TREF) process. The solvent power is usually changed by a solvent-non-solvent combination under isothermal conditions.

Type:Preparative Fractionation

Fully automatic preparation and fractionation
Up to 20 grams of polymer, depending on the sample
Column-based fractionation
Unlimited number of fractions (up to 9 fractions, no need to change bottles)
Does not handle hot solvents
Fractional distillation mode by TREF technique or by molar mass by solvent-non-solvent method.
With the integrated compressor (no liquid coolant required), subambient operation can be achieved.
Through the exchange column, fractionation can be performed by thermal gradient or solvent gradient interaction chromatography.
