PEG 300 10ml

PEG 300 10 mL

Polyethylene Glycol 300 (PEG 300) 10 mL is a high-purity pharmaceutical-grade excipient developed for laboratory research, analytical testing, and controlled in-vitro applications. Researchers commonly use PEG 300 as a versatile solvent, solubiliser, and formulation vehicle because of its excellent compatibility with a wide range of research compounds and laboratory protocols.

Each bottle contains 10 mL of pharmaceutical-grade PEG 300 as a clear, viscous liquid with a purity of 99.9% or higher. Furthermore, its neutral pH and broad solvent compatibility make it suitable for preparing research formulations, peptide and protein reconstitution, and lipid nanoparticle development. The product is supplied in an amber multi-dose bottle with a reusable plastic cap to help protect the contents from light exposure during storage and repeated laboratory use.

Additionally, PEG 300 mixes readily with water and many common laboratory solvents, making it a reliable choice for research formulations that require consistent solubility and stability. As a result, laboratories frequently use it as an excipient, solubiliser, stabiliser for lipid nanoparticles, and vehicle for peptide or protein reconstitution.

Store the bottle at 20-25°C in a cool, dry environment away from direct light and moisture. Also, keep the container tightly sealed when not in use. The product remains stable for 24 months unopened and for up to 28 days after opening when handled aseptically.

For laboratory research only. Do not use this product for human or animal consumption. Likewise, use it only for research applications, including formulation development, peptide and protein reconstitution, and controlled laboratory studies. Finally, qualified laboratory personnel should handle this product according to established laboratory safety procedures.
