Product Overview
Tween 80 LR is a high-quality non-ionic surfactant widely used in laboratories for its superior emulsifying and solubilizing properties. As a polyoxyethylene sorbitan monooleate, it effectively reduces surface tension, enabling the formation of stable oil-in-water emulsions. This lab-grade reagent is particularly valued for its ability to enhance the solubility of hydrophobic compounds, making it indispensable in biochemical and analytical applications. The liquid form ensures easy handling and precise dosing, while its LR grade guarantees consistent performance in sensitive experimental setups. Tween 80 LR is chemically stable under standard lab conditions, compatible with a wide range of aqueous and organic systems, and does not interfere with most analytical techniques. Its low toxicity profile and biodegradability further contribute to its preference in controlled laboratory environments. Whether used as a standalone emulsifier or in combination with other surfactants, Tween 80 LR delivers reliable results without compromising experimental integrity.
FAQs
1. What is the chemical composition of Tween 80 LR?
Tween 80 LR is polyoxyethylene (20) sorbitan monooleate, a non-ionic surfactant derived from oleic acid and sorbitol.
2. Is Tween 80 LR compatible with cell culture applications?
While primarily used for emulsification, its compatibility depends on concentration and cell type; always validate with pilot tests.
3. How should Tween 80 LR be stored for long-term stability?
Store in a cool, dry place away from direct sunlight, tightly sealed to prevent moisture absorption and oxidation.
4. Can Tween 80 LR be autoclaved for sterile applications?
Autoclaving is not recommended as high temperatures may degrade the surfactant; use sterile filtration instead.
5. What are the key differences between Tween 80 LR and food-grade Tween 80?
LR grade undergoes stricter purity testing for lab use, while food-grade complies with FDA regulations for consumables.
