Premium Borosilicate Glass Separatory Funnel – High-Efficiency Liquid-Liquid Extraction Vessel

Streamline your chemical purification and extraction workflows with our professional-grade Glass Separatory Funnel. Masterfully crafted from high-purity borosilicate glass, this premium laboratory apparatus features a classic conical shape with a wide top opening and a tapered lower neck. It is the industry-standard instrument for liquid-liquid extractions, enabling the precise, clean separation of immiscible liquids based on their varying densities.

Key Applications:

• Liquid-Liquid Extractions: The primary tool used in organic chemistry to separate a mixture’s components into two distinct solvent phases (aqueous and organic).

• Chemical Washing & Purification: Ideal for washing synthesized crude mixtures with water or brine solutions to remove unreacted acids, bases, or salts.

• Controlled Solution Addition: Functions excellently as a dropping funnel to introduce liquid reagents or reactants into a reaction flask slowly and at a regulated rate.

• Essential Oil & Extract Isolation: Widely utilized in commercial laboratory distillation setups to isolate pure essential oils and botanical extracts from water layers.

Product Features:

• Industrial-Strength Borosilicate Glass: Offers superior resistance to thermal shock and chemical corrosion, ensuring complete inertness against aggressive acids, bases, and volatile organic solvents.

• Precision Stopcock Control: Equipped with a high-performance PTFE (Teflon) or ground glass stopcock that ensures a leak-proof seal and smooth, ultra-precise fluid flow regulation.

• Standard Ground Glass Joint: Features a precision-ground top neck (equipped with a matching chemical-resistant stopper) to prevent evaporation or spillage during vigorous shaking and venting phases.

⚠️ Safety and Handling: Liquid-liquid extraction often generates significant vapor pressure inside the funnel, especially when using volatile solvents like ether or dichloromethane. Always vent the funnel frequently by turning it upside down and opening the stopcock away from yourself and others. Inspect the glassware for chips or hairline cracks before use. Wear comprehensive Personal Protective Equipment (PPE), including chemical-resistant gloves and safety goggles.
