FAQs
What is the difference between PEG 300 and other molecular weights?
PEG 300 has a lower molecular weight (average 300 g/mol) compared to higher variants like PEG 4000. This results in higher solubility, lower viscosity, and different biological properties. PEG 300 is preferred when rapid diffusion or lower viscosity is required in applications.
Can I use this PEG 300 for cell culture applications?
Yes, this synthesis grade is suitable for cell culture applications. However, for highly sensitive cell lines, you may want to consider cell culture-tested grades. Always perform compatibility tests with your specific cell type before full-scale use.
How should I dispose of unused PEG 300?
Follow your institution’s chemical waste disposal protocols. PEG 300 is generally considered low-hazard waste, but local regulations may vary. Never dispose of it down laboratory drains without proper authorization.
Is this product sterile?
This product is not supplied sterile. If sterility is required for your application, you’ll need to sterilize it using appropriate methods like filtration through 0.22 μm membranes before use.
What’s the shelf life of Polyethylene Glycol 300?
When stored properly in its original, unopened container, this product has a shelf life of 3-5 years. After opening, use within 12 months for optimal performance. Always check for any changes in appearance or odor before use.
