Product Overview
This 99.9% pure chloroform is an ultra-high-quality solvent designed for critical laboratory applications where moisture contamination must be absolutely minimized. The extra dry formulation undergoes rigorous stabilization processes to prevent degradation, ensuring consistent performance in sensitive procedures. Packaged under AcroSeal® technology, it maintains exceptional purity throughout storage and usage. The solvent’s low water content (typically <0.005%) makes it particularly suitable for applications like nucleic acid extraction where even trace moisture can compromise results. Its high density (1.48 g/mL at 20°C) and complete miscibility with most organic solvents provide excellent extraction capabilities. The product comes in amber glass bottles to prevent photodegradation, with PTFE-lined caps to maintain seal integrity. Each batch undergoes comprehensive GC analysis to verify the 99.9% purity specification, with certificates of analysis available for quality assurance. The stabilized formulation includes amylene as a preservative to prevent phosgene formation during storage.
FAQs
1. What makes this chloroform “extra dry” compared to regular grades?
The extra dry designation indicates this chloroform contains less than 0.005% water content, achieved through specialized drying processes and verified by Karl Fischer titration. Regular grades typically contain 0.01-0.05% water, which can interfere with moisture-sensitive reactions.
2. How does the AcroSeal® packaging benefit this product?
AcroSeal® technology uses a multi-layer barrier system that prevents moisture ingress and solvent evaporation. The packaging includes a PTFE-lined cap and specialized bottle design that maintains the extra dry specification throughout the product’s shelf life.
3. What stabilizers are used in this chloroform formulation?
This formulation uses amylene (typically 0.5-1%) as the primary stabilizer to prevent phosgene formation. The stabilization is carefully balanced to maintain product integrity without interfering with analytical applications.
4. Can this chloroform be used for long-term storage of samples?
While suitable for many extraction procedures, the stabilized formulation is primarily designed for immediate use rather than long-term sample storage. For storage applications, consider adding molecular sieves to maintain dryness over extended periods.
5. What’s the typical shelf life for unopened bottles?
When stored properly in original packaging at 15-25°C, away from direct sunlight, unopened bottles maintain their specifications for 24 months from the date of manufacture.
