FAQs
What is the difference between Tween 40 and other polysorbates?
Tween 40 (Polysorbate 40) is specifically derived from sorbitol and oleic acid, giving it unique emulsifying properties compared to other polysorbates like Tween 20 or 80. Its HLB value of ~15.6 makes it particularly effective for oil-in-water emulsions.
Can I use this for cell culture applications?
Yes, this extrapure grade is suitable for cell culture work. However, we recommend performing a compatibility test with your specific cell lines, as some cells may be sensitive to surfactants.
How should I store Polysorbate 40?
Store at room temperature (15-25°C) in a tightly sealed container. Avoid exposure to moisture and extreme temperatures to maintain product integrity.
Is this product sterile?
While manufactured under strict quality control, this product is not sterile. For sterile applications, you may need to filter-sterilize it using appropriate laboratory techniques.
What’s the typical shelf life of Polysorbate 40?
When stored properly, this product maintains its quality for at least 2 years from the date of manufacture. Always check the expiration date on your specific batch.
