General description

This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food. Find all available reference materials for compounds listed in 10/2011 here
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. Polyethylene glycol (PEG) is an eco-friendly, biodegradable polymer widely used in pharmaceuticals and cosmetics. Its non-toxic nature and versatility make it a sustainable choice, derived from renewable resources, contributing to greener product formulations. Click here for more information.

Other Notes

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.
