Get that HIGH purity EVERY TIME!
Looking for unmatched control and consistency in your PEGylation workflows?
We provide monodisperse, high-purity PEG derivatives (up to 2000 Da MW) that outperform conventional polydisperse PEGs. Our precision-engineered PEG-45 products deliver exceptional reproducibility from early R&D through scale-up, making them ideal for demanding applications in the pharmaceutical and biotech industries.
Why settle for polydisperse?
Commercial PEG 2000 products often contain broad molecular weight distributions, which can compromise consistency and performance. Our monodisperse PEGs eliminate this variability, ensuring purity, reproducibility, and peace of mind.
