2000ml Glass Separatory Funnel Labware PTFE Stopcock Iron Ringstand

Description

Product Overview

The 2000ml Glass Separatory Funnel Set from Labware is engineered for high‑performance liquid‑liquid extraction in research and industrial laboratories. Constructed from premium borosilicate glass, the funnel offers exceptional chemical resistance, thermal stability, and clarity, allowing users to monitor phase separation with confidence. The integrated PTFE stopcock provides a smooth, leak‑free flow control that tolerates a wide range of solvents, acids, and bases without degradation. Complementing the funnel, the iron ringstand hardware includes a robust cast‑iron base, a 24‑inch stainless steel rod, and a precisely machined electroplated ring, delivering a secure, adjustable mounting solution that fits standard lab benches and stands. The set is designed for ease of cleaning, with smooth interior surfaces that minimize residue buildup and facilitate rapid turnaround between experiments.

Usage

This separatory funnel set excels in a variety of laboratory environments, from academic chemistry departments to pharmaceutical development labs and environmental testing facilities. It is ideal for tasks such as solvent extraction, phase separation, acid‑base titration, and sample preparation for analytical techniques like gas chromatography or mass spectrometry. The 2000ml capacity accommodates larger sample volumes, reducing the need for multiple transfers and minimizing exposure to hazardous chemicals. The PTFE stopcock’s precision control enables users to drain the lower phase while retaining the upper phase, a critical step in many purification protocols. The iron ringstand provides a stable platform that can be clamped to a bench or stand, ensuring the funnel remains upright during vigorous mixing or when subjected to temperature fluctuations.

FAQ

What solvents can the PTFE stopcock handle?

The PTFE stopcock is compatible with most organic solvents, acids, bases, and aqueous solutions, including dichloromethane, chloroform, methanol, ethanol, hydrochloric acid, and sodium hydroxide, without swelling or degradation.

Can the funnel be used for temperature‑controlled processes?

Yes. The borosilicate glass construction tolerates rapid temperature changes, making the funnel suitable for heating, cooling, and reflux operations within typical laboratory temperature ranges.

Is the ringstand adjustable for different bench heights?

The included 24‑inch stainless steel rod can be positioned at multiple heights, and the cast‑iron base can be clamped securely to accommodate a variety of bench configurations and user preferences.

How do I clean the funnel and stopcock after use?

Rinse the glass funnel with distilled water followed by a suitable solvent for the chemicals used. The PTFE stopcock can be cleaned by flushing with the same solvent and wiping the exterior with a lint‑free cloth. For thorough cleaning, disassemble the stopcock according to the user manual and soak the components in a mild detergent solution.

What warranty does Labware provide for this set?

Labware offers a one‑year limited warranty covering any manufacturing defects in the glass, stopcock, or ringstand hardware. Technical assistance is available through the Labware customer service team for troubleshooting and replacement parts.
