Product Overview
Polyethylene glycol 200 (PEG 200) from BAKER™ is a low-molecular-weight, water-soluble liquid widely used in laboratory settings for its versatility and reliability. This high-purity grade ensures minimal impurities, making it suitable for sensitive applications in molecular biology, biochemistry, and as a solvent in various chemical processes. PEG 200 is known for its hygroscopic nature, which allows it to retain moisture, making it valuable in formulations requiring controlled humidity or as a plasticizer in polymer systems. Its low viscosity and excellent solubility in water and organic solvents enhance its utility in sample preparation, protein crystallization, and as a medium for enzymatic reactions. The product is rigorously tested to meet laboratory standards, ensuring consistent performance across experiments. Whether used in research or routine lab procedures, BAKER™ PEG 200 provides the precision and reproducibility needed for accurate results.
FAQs
1. What is the shelf life of Polyethylene glycol 200?
When stored in a tightly sealed container at room temperature, PEG 200 typically has a shelf life of 2-3 years. Always check for any changes in appearance or odor before use.
2. Is PEG 200 compatible with organic solvents?
Yes, PEG 200 is soluble in a wide range of organic solvents, including ethanol, acetone, and chloroform, making it versatile for various chemical applications.
3. Can PEG 200 be used as a substitute for other PEG grades?
While PEG 200 shares similar properties with other PEG grades, its low molecular weight makes it more suitable for applications requiring lower viscosity and higher solubility.
4. How should PEG 200 be stored to maintain its quality?
Store PEG 200 in a cool, dry place away from direct sunlight and moisture. Ensure the container is tightly sealed to prevent contamination or degradation.
5. Is this product suitable for use in cell culture applications?
PEG 200 is not typically recommended for cell culture applications due to its low molecular weight, which may affect cell viability. Higher molecular weight PEGs are generally preferred for such uses.
