Product Description
Polyethylene Glycol 4000 (PEG 4000) is a high-molecular-weight polymer widely used in laboratories for synthesis, purification, and stabilization processes. This Merck-grade PEG 4000 is designed for research and industrial applications where consistency and purity are critical. Its non-toxic, hydrophilic nature makes it ideal for protein crystallization, cell fusion experiments, and as a solvent in pharmaceutical formulations.
Whether you’re a student working on a biochemistry project or a researcher developing new drug delivery systems, this PEG 4000 offers reliable performance. The 1 KG pack size ensures you have an ample supply for multiple experiments without frequent reordering. At eqipped, we source directly from Merck to guarantee authenticity and batch-to-batch consistency.

PEG 4000 is particularly valued in molecular biology for its ability to precipitate DNA and proteins while maintaining their structural integrity. Its low volatility and high solubility in water and organic solvents make it a versatile choice for various laboratory protocols. Researchers also use it as a fusion agent in hybridoma technology and as a cryoprotectant for cell preservation.
When purchasing polyethylene glycol 4000 for synthesis, always verify the grade matches your application requirements. This Merck product meets stringent quality standards, ensuring minimal impurities that could interfere with sensitive experiments. The flake or powder form allows for easy dissolution and precise measurement in your protocols.
Key Applications of Polyethylene Glycol 4000
This versatile compound finds use in numerous laboratory applications:
In pharmaceutical research, PEG 4000 serves as an excipient in drug formulations, improving solubility and bioavailability of active ingredients. Biochemists rely on it for protein purification through precipitation methods. Molecular biologists use it in DNA extraction protocols and as a blocking agent in hybridization experiments.
The compound’s inert nature makes it suitable for medical device coatings and as a lubricant in various industrial processes. Its ability to form complexes with other molecules also makes it valuable in nanotechnology research for creating drug delivery systems.
Safety and Handling
While PEG 4000 is generally considered safe for laboratory use, proper handling procedures should always be followed. Wear appropriate personal protective equipment including gloves and safety goggles when working with the powder form to avoid skin and eye irritation. Store in a cool, dry place away from incompatible substances.
For disposal, follow your institution’s chemical waste protocols. PEG 4000 is not classified as hazardous waste, but local regulations may apply to laboratory chemicals.
Why This Product Stands Out
Choosing Merck’s Polyethylene Glycol 4000 through eqipped ensures you receive a product that has undergone rigorous quality control. The synthesis grade designation means it’s purified to remove contaminants that could affect experimental results. The consistent molecular weight distribution (average 4000 Da) provides predictable performance in your applications.
Our 1 KG packaging offers excellent value for laboratories with regular PEG 4000 requirements. The resealable container helps maintain product integrity between uses. When you buy polyethylene glycol 4000 online from eqipped, you benefit from our streamlined supply chain that connects Indian researchers directly with premium lab supplies.
FAQs
What is the difference between PEG 4000 and other molecular weights?
PEG 4000 has an average molecular weight of 4000 Daltons, making it ideal for applications requiring moderate viscosity and solubility. Lower molecular weights like PEG 400 are liquids, while higher weights like PEG 8000 form more viscous solutions. The choice depends on your specific protocol requirements.
Can I use this PEG 4000 for medical applications?
This product is labeled “for synthesis” and is intended for laboratory use only. For medical or pharmaceutical applications, you would need pharmaceutical-grade PEG that meets additional regulatory requirements. Always check the grade specification matches your intended use.
How should I store polyethylene glycol 4000?
Store in a tightly sealed container at room temperature, away from moisture and direct sunlight. Proper storage maintains the product’s physical properties and prevents contamination. The shelf life is typically 2-3 years when stored correctly.
What is the solubility of PEG 4000 in water?
PEG 4000 is highly soluble in water, typically dissolving at concentrations up to 50% w/v at room temperature. The dissolution rate can be improved by gentle heating and stirring. It’s also soluble in many organic solvents like ethanol and acetone.
Does eqipped offer smaller quantities of PEG 4000?
Currently, we offer this product in 1 KG packaging which provides excellent value for most laboratory needs. For specialized requirements, please contact our customer service team to discuss potential custom packaging options.
