Product Description
Polysorbate 80, commonly known as Tween 80, is a versatile non-ionic surfactant widely used in laboratories for emulsifying oils, stabilizing suspensions, and enhancing solubility in aqueous solutions. This Qualigens-grade Tween 80 is highly purified, making it suitable for sensitive applications like cell culture, biochemical assays, and pharmaceutical research.
Whether you’re a student setting up experiments or a researcher working on advanced projects, this laboratory-grade Tween 80 ensures consistent performance. Its hydrophilic-lipophilic balance (HLB) of 15 makes it an excellent choice for creating stable emulsions in both academic and industrial settings.
At eqipped, we understand the importance of reliable lab supplies. That’s why we source high-quality chemicals like this Tween 80 to meet the exacting standards of Indian researchers, educators, and students. The 500 mL pack size offers great value for regular lab use while maintaining freshness and efficacy.
Key Applications of Polysorbate 80 (Tween 80)
This surfactant finds applications across various scientific disciplines:
In microbiology labs, it’s often used to prepare culture media where uniform dispersion of nutrients is critical. Biochemists rely on it for protein solubilization and membrane studies. Pharmaceutical researchers use it in drug formulation to improve bioavailability of hydrophobic compounds.
For students working on chemistry projects, Tween 80 serves as an excellent demonstration of surfactant properties. Its ability to reduce surface tension makes it valuable in cleaning solutions and as a wetting agent in various analytical procedures.
Handling and Storage Recommendations
To maintain the integrity of your Tween 80, store the bottle tightly sealed in a cool, dry place away from direct sunlight. While this is a laboratory-grade product, it’s always good practice to handle it with standard lab safety measures – wear appropriate PPE and work in a well-ventilated area.
The viscous nature of Tween 80 means it pours slowly. For precise measurements, consider using a clean, dry pipette or syringe. If you notice any cloudiness or separation, gentle warming to room temperature and mixing usually restores uniformity.
Why This Grade Matters
Not all Tween 80 products are created equal. This Qualigens SQ grade is specifically processed to remove impurities that could interfere with sensitive applications. Unlike industrial grades, it’s tested for consistency in critical parameters like pH, viscosity, and surfactant activity.
For researchers working on cell culture, this purity is particularly important as residual impurities in lower-grade surfactants can affect cell viability and experimental outcomes. The batch-to-batch consistency ensures reproducible results in your experiments.
Common Questions About Using Tween 80
Many first-time users wonder about the appropriate concentration for their applications. While optimal concentrations vary, most protocols use 0.05% to 0.5% solutions. For cell culture applications, concentrations typically range between 0.01% to 0.1%.
Another frequent question concerns compatibility with other reagents. Tween 80 generally works well with most aqueous systems but may interact with certain proteins or ionic surfactants. Always check your specific protocol requirements.
FAQs
What is the shelf life of Polysorbate 80 (Tween 80)?
When stored properly in its original container, Tween 80 has a shelf life of 2-3 years. Always check the manufacturer’s expiration date on the label.
Can I use this Tween 80 for food applications?
This is a laboratory-grade product intended for research use only. For food applications, you would need food-grade certified Tween 80.
How do I prepare a 1% Tween 80 solution?
Add 1 mL of Tween 80 to 99 mL of distilled water and mix thoroughly. For better dissolution, you can gently warm the solution while stirring.
Is Tween 80 the same as Polysorbate 80?
Yes, Tween 80 is the trade name for Polysorbate 80. They are chemically identical – a polyoxyethylene sorbitan monooleate compound.
What safety precautions should I take when handling Tween 80?
While generally low-hazard, always wear appropriate lab protection (gloves, goggles) and work in a ventilated area. Avoid skin and eye contact, and wash hands after handling.
