Product Overview
CHLOROFORM 99.5% GC is a high-purity, laboratory-grade solvent designed for critical applications requiring minimal impurities and consistent performance. This non-stabilized chloroform is distilled to meet stringent GC (Gas Chromatography) standards, ensuring low background interference and reliable results in analytical techniques. Its exceptional clarity and 99.5% minimum purity make it suitable for sensitive extractions, chromatographic separations, and spectroscopic analyses where trace contaminants could compromise accuracy. The solvent is packaged in amber glass bottles to prevent photodegradation, preserving its stability during storage and handling. Compatible with most organic compounds, it serves as an efficient medium for dissolving lipids, alkaloids, and other non-polar substances without leaving residual byproducts. For optimal shelf life, store in a cool, well-ventilated area away from direct sunlight and ignition sources. Always handle under a fume hood with appropriate PPE due to its volatile and mildly toxic nature. This product adheres to international lab reagent specifications, providing researchers and analysts with a dependable solvent for precise, repeatable experiments.
FAQs
1. What is the difference between GC-grade and AR-grade chloroform?
GC-grade chloroform undergoes additional purification to remove trace impurities that could interfere with gas chromatography or spectroscopy, while AR (Analytical Reagent) grade is suitable for general lab use but may contain slightly higher residual contaminants.
2. Can this chloroform be used for DNA extraction?
Yes, 99.5% GC-grade chloroform is commonly used in phenol-chloroform DNA extraction protocols due to its high purity and ability to effectively separate nucleic acids from proteins and lipids.
3. Is this chloroform stabilized with ethanol or amylenes?
No, this is non-stabilized chloroform. Stabilizers like ethanol or amylenes are added to some commercial grades to prevent decomposition, but GC-grade chloroform is typically used without additives for analytical purity.
4. What precautions should be taken when storing chloroform?
Store in tightly sealed amber glass bottles at room temperature (15–25°C), away from heat, flames, and oxidizing agents. Use a dedicated solvent cabinet with ventilation to prevent vapor accumulation.
5. Does this chloroform leave residues after evaporation?
When used as directed, 99.5% GC-grade chloroform evaporates cleanly with negligible residue, making it ideal for applications where solvent purity is critical, such as sample preparation for GC-MS or FTIR analysis.
