Product Overview
Polyethylene Glycol 200 LR is a low-molecular-weight, water-soluble polymer widely used in laboratories for its versatility and stability. This clear, colorless liquid offers excellent solvent properties, making it ideal for dissolving a variety of organic and inorganic compounds. Its low volatility and hygroscopic nature ensure consistent performance in experiments, while its non-toxic profile enhances safety during handling. The LR (Laboratory Reagent) grade guarantees high purity, minimizing impurities that could interfere with sensitive applications. Polyethylene Glycol 200 LR serves as an effective plasticizer, humectant, and medium for chemical synthesis, ensuring reliable results across diverse protocols. Its compatibility with water and organic solvents further broadens its utility in formulations. Whether used as a solvent, stabilizer, or reaction medium, this grade maintains consistency in viscosity and chemical behavior, making it a trusted choice for researchers. Store in a tightly sealed container in a cool, dry place to preserve its properties over time.
FAQs
1. What is the shelf life of Polyethylene Glycol 200 LR?
When stored properly in a sealed container away from moisture and direct sunlight, Polyethylene Glycol 200 LR typically retains its stability for up to 2 years.
2. Can this grade be used as a substitute for higher molecular weight PEGs?
Polyethylene Glycol 200 LR has distinct properties due to its low molecular weight, so it may not fully replace higher molecular weight PEGs in applications requiring thicker viscosity or different solubility characteristics.
3. Is this product compatible with aqueous and organic solvents?
Yes, Polyethylene Glycol 200 LR is miscible with water and many organic solvents, including ethanol, acetone, and chloroform, making it versatile for various formulations.
4. What precautions should be taken while handling this chemical?
While generally low in toxicity, it is recommended to wear gloves and safety goggles to avoid skin or eye irritation, especially during prolonged exposure.
5. How does the LR grade differ from technical or industrial grades?
The LR grade is purified to meet laboratory standards, ensuring minimal impurities, whereas technical or industrial grades may contain higher levels of contaminants unsuitable for precise research applications.
