FAQs
1. What is the shelf life of diethylene glycol LR when stored properly?
When stored in a tightly sealed container away from moisture and direct sunlight at room temperature, diethylene glycol LR maintains its stability for at least 24 months from the date of manufacture.
2. Can this product be used as a substitute for ethylene glycol in laboratory applications?
While both are glycols, diethylene glycol has different physical properties including higher viscosity and boiling point. It can serve as an alternative in some applications but may require protocol adjustments due to these differences.
3. What type of container material is recommended for long-term storage?
For optimal storage, use containers made of high-density polyethylene (HDPE) or glass with PTFE-lined caps to prevent moisture absorption and maintain product purity.
4. Does this product contain any stabilizers or additives?
Diethylene glycol LR grade is supplied without added stabilizers or preservatives, maintaining its pure chemical composition as specified for laboratory reagent standards.
5. What safety precautions should be taken when handling this chemical?
Always wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and work in a well-ventilated area or fume hood when handling diethylene glycol.
