Amber Colour Separating Funnels with PTFE Key Stopcock and Interchangeable Glass Stopper, Pear Shape

Glass Agencies presents Amber Colour Separating Funnels with PTFE Key Stopcock and Interchangeable Glass Stopper, Pear Shape, created for laboratories that require smooth phase separation while protecting light-sensitive samples. Each funnel is shaped from refined amber-tinted glass that helps shield contents from excessive illumination, supporting the stability of organic layers, solvents, and reagents that may alter under strong light. This protective shading maintains sample character during extraction, washing, or partitioning steps, ensuring dependable outcomes across repeated procedures. The classic pear shape promotes efficient layer formation, allowing upper and lower phases to settle clearly for easy separation. Its curvature guides liquids toward the stopcock with steady movement, minimizing turbulence and helping users achieve clean, controlled transfers. The PTFE key stopcock provides smooth, consistent flow control, resisting chemical interactions and supporting long-term performance without swelling or sticking. Users can fine-tune the release of each layer with confidence, aiding precise division of immiscible liquids. Along with this, the interchangeable glass stopper fits securely in the funnel neck, forming a tight closure that helps limit evaporation, contamination, or accidental leakage during shaking or mixing. The stopper’s ground finish allows easy replacement whenever required while maintaining a firm seal. Internal surfaces of the funnel are polished to reduce residue retention and promote predictable liquid movement, aiding clarity in separation boundaries. Glass Agencies upholds strict manufacturing oversight to ensure each unit reflects accurate dimensions, smooth surface finish, consistent coloration, and dependable mechanical action of the PTFE stopcock. The sturdy amber glass construction withstands routine washing and exposure to a wide range of laboratory chemicals, supporting a long service life while maintaining reliable function. The distinctive amber appearance also assists users in quickly identifying the funnel among standard transparent glassware. Before dispatch, every funnel undergoes detailed inspection to verify stopper fit, stopcock smoothness, structural quality, and surface integrity.
