Non disponible en dehors du Royaume-Uni et de l'Irlande

Application

PEG may have been used in understanding properties of Sol-Gel protein Chips using large-scale material screening and selection.

Components

ReadyCal Standards are polymer cocktails pre-weighed into autosampler vials for the convenient calibration of GPC/SEC/GFC systems. This kit contains 10 sets of 3 color-coded vials, each containing three or four PEO/PEG standards of different molar masses. Molar masses range from ~250 to ~1,000,000 Da and are carefully selected so that polymer traces are baseline separated.This kit contains sufficient material for at least 10 calibrations and includes an instruction manual and calibration curve with measurement conditions.Suitable for calibrations in aqueous solutions, DMF and DMAc.

General description

PEG also known as ethylene glycol, is a colorless, odorless, viscous dihydroxy alcohol. It is a polyether compound with applications ranging from industrial manufacturing to medicine. It is the most important glycol that is commercially available, and finds application as an antifreeze and coolant, in hydraulic fluids, and in the manufacture of low-freezing dynamites and resins. It is widely used as covalent modifier of biological macromolecules.
