Product Description
Polyethylene Glycol 400 (PEG 400) is a versatile, water-soluble polymer widely used in laboratories for synthesis, biochemical assays, and as a solvent or stabilizer. This high-purity grade from Merck ensures consistency and reliability in experimental workflows. Whether you’re working on protein crystallization, cell culture media supplementation, or as a vehicle for drug delivery studies, PEG 400 offers excellent solubility and low toxicity.
Researchers and students often choose PEG 400 for its ability to enhance solubility of hydrophobic compounds, making it indispensable in formulation development. Its hygroscopic nature also makes it useful in maintaining moisture in samples. For educators, this reagent serves as a practical example in chemistry and biochemistry courses, demonstrating polymer properties and solvent interactions.

Key Applications of Polyethylene Glycol 400
PEG 400 finds extensive use in both academic and industrial research settings. In molecular biology, it’s commonly employed as a precipitating agent in DNA and RNA isolation protocols. Pharmacologists rely on it for drug solubility studies, while material scientists use it in polymer blend research. Its role in cryopreservation media for cell storage is another critical application, where it helps prevent ice crystal formation.
For students working on thesis projects or practical experiments, PEG 400 offers a safe and effective way to explore concepts like osmosis, viscosity, and polymer chemistry. The 500 ml pack size provides sufficient quantity for multiple experiments while maintaining affordability.
Handling and Storage Recommendations
Store polyethylene glycol 400 at room temperature in a tightly sealed container to prevent moisture absorption. While generally considered low-hazard, it’s good practice to handle it in a well-ventilated area and use standard lab safety equipment. Always refer to the material safety data sheet for complete handling instructions.
For long-term storage, keep the bottle away from direct sunlight and heat sources. The shelf life remains stable for years when stored properly, making it a cost-effective choice for labs with intermittent usage patterns.
Why This Product Stands Out
The Merck brand ensures you’re working with a reagent that meets stringent quality control standards. This particular batch (8.07485.0521) is specifically designated for synthesis applications, meaning it undergoes additional purification steps to remove impurities that could interfere with sensitive reactions.
Compared to industrial-grade alternatives, this synthesis-grade PEG 400 offers superior batch-to-batch consistency. This reliability is crucial when reproducing experimental results or scaling up processes from bench to pilot scale.

FAQs
What is the molecular weight range of PEG 400?
PEG 400 typically has an average molecular weight between 380-420 g/mol, with the “400” designation referring to this approximate range rather than an exact value.
Can I use this PEG 400 for cell culture applications?
While primarily labeled for synthesis, this grade is suitable for many cell culture applications. However, for critical cell culture work, you might want to consider cell culture-tested grades for additional assurance.
How does PEG 400 differ from other PEG grades?
PEG 400 is a liquid at room temperature, unlike higher molecular weight PEGs which are solids. Its lower molecular weight makes it more suitable for applications requiring good solubility and penetration properties.
What safety precautions should I take when handling PEG 400?
While generally safe, avoid inhalation and direct eye contact. Use in a fume hood when handling large quantities. In case of skin contact, wash with soap and water.
Can I get a smaller quantity than 500 ml for testing purposes?
Currently, this product is available in 500 ml packaging. For smaller quantities, consider checking our other PEG products or contact our customer support for special requests.
