FAQs
What is the molecular weight range for this PEG 20,000?
The product has an average molecular weight of 20,000 Daltons, with a typical range of 18,000-22,000 Daltons as per manufacturer specifications.
Can this PEG be used for cell culture applications?
Yes, this laboratory-grade PEG 20,000 is suitable for cell culture applications including cell fusion protocols, though we recommend sterile filtering before use in sensitive cell cultures.
What’s the solubility of polyethylene glycol 20,000 in water?
PEG 20,000 is freely soluble in water at room temperature, typically forming clear solutions at concentrations up to 50% w/v.
How does this compare to lower molecular weight PEGs?
Higher molecular weight PEGs like this 20,000 variant have lower osmotic pressure and different precipitation characteristics compared to lower MW versions, making them better suited for certain crystallization applications.
What’s the typical delivery time for this product in India?
Most orders are dispatched within 1-2 business days. Delivery times vary by location but typically range from 3-7 days for major cities when you buy online from eqipped.
