FAQs
What is the molecular weight range for PEG 20000?
Polyethylene Glycol 20000 typically has an average molecular weight between 18,000 and 22,000 g/mol, with Merck’s stabilized version offering consistent performance within this range.
Can PEG 20000 be used for cell culture applications?
Yes, PEG 20000 is commonly used in cell culture for fusion experiments and as a cryoprotectant. However, ensure proper sterilization before use in aseptic conditions.
How does PEG 20000 differ from lower molecular weight PEGs?
Higher molecular weight PEGs like 20000 have lower solubility in water and form more viscous solutions compared to lower MW variants. They’re preferred for applications requiring larger exclusion volumes.
What’s the shelf life of polyethylene glycol 20000?
When stored properly in sealed containers, PEG 20000 has a shelf life of 3-5 years. The stabilized version from Merck maintains its properties longer than unstabilized alternatives.
Is PEG 20000 suitable for food or cosmetic applications?
While lab-grade PEG 20000 is highly purified, it’s not certified for food or cosmetic use. For those applications, specific food-grade or cosmetic-grade PEGs should be sourced.
