Polyethylene glycol (PEG-400) (1.0 L)

Buy PEG-400 (Polyethylene glycol)

Want to buy PEG-400? Polyethylene glycol is a hydrophilic polymer with a molecular mass of about 400 u. The substance forms as a colorless, odorless and viscous liquid at room temperature. Due to its strong hydrophilic properties and good miscibility with water and various other organic solvents, it is often used as a process aid in laboratories.

What is PEG-400 used for?

PEG-400 is used as an excipient and process fluid in laboratories and industry. In laboratories, it is used as a solvent or carrier in chemical processes and in biotechnological and analytical processes, such as filtration and separation methods.

In industrial environments it is used as a compatible process aid in a wide range of technical applications where a water-attracting, low-reactive liquid is required. Use depends on the application and is the responsibility of the professional user.

Chemical properties

PEG-400 is a hydrophilic polymer composed of ethylene glycol units and is relatively unreactive. It is highly soluble in water and miscible with many organic solvents. Its relatively low molecular weight explains its liquid, viscous form at room temperature.

Storage and use

Store the product in a cool, dry place in tightly closed containers. Use in suitable work environments and avoid unnecessary contact with skin and eyes. Always follow the applicable safety procedures within your organization.
