Precision Ground Glassware for Professional Solvent Extraction
Engineered for high-purity chemical extractions, our Pear-Shaped Separating Funnels utilize a traditional precision-ground glass stopcock to ensure a vacuum-tight seal. Manufactured from premium 3.3 Borosilicate Glass, this funnel offers the highest degree of chemical resistance and thermal stability required for international analytical protocols. The conical design is specifically optimized for sharp phase interfaces and maximum volume recovery during liquid-liquid extractions.
Precision-Ground Glass Fitting
The stopcock and interchangeable stopper are individually ground to a standard taper, providing an airtight fit and smooth manual control when used with appropriate laboratory lubricants.
Heavy-Duty Chemical Durability
Constructed from low-expansion glass (USP Type I), this funnel is resistant to aggressive acids, alkalis, and organic solvents, making it ideal for pharmaceutical and petrochemical research.
