Product Overview
Ethylene glycol, 99.8% anhydrous, AcroSeal® is a high-purity, low-moisture solvent engineered for demanding laboratory applications where water content must be minimized. This colorless, odorless liquid features exceptional thermal stability and hygroscopic properties, making it a critical reagent in organic synthesis, polymer production, and as a cryoprotectant in biological sample preservation. The AcroSeal® packaging ensures extended shelf life by preventing atmospheric moisture absorption, while the 99.8% purity specification guarantees consistent performance in analytical procedures. With a boiling point of 197.3°C and miscibility in water and alcohols, this grade is particularly valued in chromatographic applications and as a reaction medium for temperature-sensitive processes. The anhydrous nature eliminates interference from water molecules in spectroscopic analyses, while its low volatility reduces evaporation losses during prolonged experiments. Compatible with most glass and PTFE labware, this ethylene glycol variant maintains its chemical integrity across a wide temperature range, from cryogenic conditions to elevated heat applications.
FAQs
1. What is the maximum allowable moisture content in this anhydrous ethylene glycol?
The 99.8% purity specification indicates a maximum moisture content of 0.2%, making it suitable for moisture-sensitive reactions.
2. Can this product be used as a substitute for propylene glycol in formulations?
While chemically similar, ethylene glycol has different toxicity profiles and viscosity characteristics compared to propylene glycol, requiring formulation adjustments.
3. What type of container material is recommended for long-term storage?
Glass or HDPE containers with PTFE-lined caps are ideal for maintaining purity during extended storage periods.
4. Does the AcroSeal® packaging require any special handling during opening?
The packaging features a tamper-evident seal that should be carefully removed to prevent contamination from environmental moisture.
5. What is the typical shelf life when stored under recommended conditions?
When stored in unopened AcroSeal® containers at room temperature, the product maintains its specifications for 24 months from the date of manufacture.
