Product Description
Polyethylene Glycol 200, often referred to as PEG 200, is a low-molecular-weight polymer widely used in laboratories for synthesis, stabilization, and as a solvent. This high-purity grade from Merck ensures reliable performance in critical applications, making it a staple in research and educational settings.
Whether you’re working on protein crystallization, cell culture, or molecular biology experiments, PEG 200 provides the consistency and purity needed for accurate results. Its hygroscopic nature makes it an excellent choice for maintaining moisture in samples, while its compatibility with aqueous solutions simplifies experimental setups.

PEG 200 is also commonly used in pharmaceutical formulations, cosmetics, and industrial applications due to its non-toxic and non-irritating properties. Researchers appreciate its ability to dissolve both polar and non-polar compounds, making it a versatile addition to any lab inventory.
When selecting polyethylene glycol 200, always prioritize products labeled “for synthesis” to ensure minimal impurities. This grade is specifically designed for laboratory use, unlike industrial variants which may contain additives unsuitable for sensitive applications.
FAQs
What is the shelf life of polyethylene glycol 200?
When stored properly in its original, tightly sealed container at room temperature, polyethylene glycol 200 typically has a shelf life of 2-3 years. Always check the manufacturer’s expiration date on the label before use.
Can I use PEG 200 for cell culture applications?
Yes, this synthesis grade PEG 200 is suitable for cell culture applications, including cryopreservation media preparation. However, always perform a small-scale test with your specific cell lines to ensure compatibility.
What’s the difference between PEG 200 and other molecular weights?
Lower molecular weight PEGs like PEG 200 are more water-soluble and have different viscosity properties compared to higher molecular weight versions. PEG 200 is particularly valued for its ability to penetrate cells and its use as a solvent.
Is this product suitable for pharmaceutical applications?
While this is a high-purity synthesis grade, for pharmaceutical applications you should use PEG 200 that’s specifically labeled as pharmaceutical grade to meet regulatory requirements.
How should I dispose of unused PEG 200?
Follow your institution’s chemical waste disposal protocols. PEG 200 is generally not considered hazardous waste, but local regulations may vary. Never pour chemicals down the drain unless specifically permitted.
