Separatory Funnel Laboy 250mL Borosilicate Glass with 4mm PTFE

Description

Product Overview

The Laboy 250 mL separatory funnel is engineered for laboratory professionals who demand precision, durability, and chemical resistance. Crafted from premium borosilicate glass, the vessel resists thermal shock and a wide range of solvents, ensuring long‑term performance even under rigorous cleaning cycles. The conical shape promotes efficient phase separation, while the pear‑shaped design provides a comfortable grip for controlled pouring and draining. Integrated with a 4 mm PTFE stopcock, the funnel offers smooth, leak‑free flow control, allowing you to stop the liquid stream at any point without dripping. Two standardized 24/40 joints—one on the top and one on the side—enable flexible connections to condensers, adapters, or other glassware, making the funnel adaptable to a variety of experimental setups. The clear glass construction allows easy visual monitoring of the interface between immiscible liquids, helping you achieve accurate separations every time.

Usage

This separatory funnel excels in a broad spectrum of laboratory applications. In organic synthesis labs, it is indispensable for liquid‑liquid extractions, where precise control over the removal of aqueous and organic layers is critical. The funnel also serves well in analytical chemistry for sample preparation, such as separating solvents before chromatography. Its robust borosilicate composition makes it suitable for high‑temperature processes, including reflux and distillation setups, where the funnel can be connected to a condenser via the 24/40 joint. Researchers in academic institutions appreciate its reliability for teaching demonstrations, allowing students to observe phase separation in real time. The PTFE stopcock’s chemical inertness ensures compatibility with aggressive reagents, while the dual joints provide the flexibility to integrate the funnel into custom apparatuses, such as multi‑stage extraction rigs or continuous flow reactors.

FAQ

What solvents can I safely use with this funnel?

The borosilicate glass is compatible with most organic solvents, including ethanol, acetone, dichloromethane, and hexane, as well as aqueous solutions. Always avoid highly concentrated strong acids or bases that exceed the glass’s chemical resistance limits.

How do I clean and maintain the PTFE stopcock?

After each use, rinse the stopcock with a suitable solvent to remove residues. For stubborn deposits, soak the stopcock in a mild detergent solution, then rinse thoroughly with distilled water. Avoid abrasive cleaning tools that could damage the PTFE surface.

Can the funnel be used for high‑temperature reflux applications?

Yes. The borosilicate glass can withstand temperatures up to 350 °C, making the funnel suitable for reflux setups when connected to a condenser via the 24/40 joint. Ensure that all connections are securely tightened to prevent leaks.

Is the funnel compatible with standard laboratory clamps and stands?

The funnel’s base is designed to fit common laboratory clamps and ring stands. Its stable, wide base provides secure positioning during extractions or distillations, reducing the risk of tipping.

What is the warranty coverage for this product?

Laboy offers a one‑year limited warranty covering manufacturing defects in the glass and PTFE stopcock. If you encounter any issues within the warranty period, contact our support team for replacement or repair options.
