EISCO Squibb Separating Funnel 100ml PTFE Stopcock 19/26 Stopper

Description

Product Overview

The EISCO Squibb Separating Funnel is engineered for demanding laboratory environments where precision, durability, and chemical resistance are paramount. Constructed from high‑quality borosilicate glass, the 100 ml capacity vessel offers excellent thermal stability and resistance to a wide range of solvents, acids, and bases, ensuring that the glass will not crack or leach under typical laboratory conditions. The integrated PTFE (polytetrafluoroethylene) stopcock delivers a smooth, leak‑free flow control, allowing users to dispense liquids with fine adjustment and minimal dead volume. Complementing the stopcock is an interchangeable 19/26 plastic stopper, designed for quick replacement and compatibility with standard laboratory glassware. The funnel’s compact dimensions—approximately 10 inches in length and 3 inches in diameter—make it easy to handle, store, and integrate into existing workflows.

Usage

This separatory funnel is ideally suited for a broad spectrum of laboratory applications, including organic synthesis, analytical chemistry, and quality‑control testing. Whether you are performing liquid‑liquid extractions, phase separations, or washing steps, the funnel’s clear borosilicate construction allows for easy visual monitoring of phase boundaries, color changes, and reaction progress. The PTFE stopcock’s precision control is especially valuable when handling viscous or hazardous liquids, as it reduces the risk of splashing and exposure. The interchangeable 19/26 stopper accommodates a variety of standard lab setups, making the funnel compatible with common ring stands, clamps, and support accessories. Researchers in academic, industrial, and pharmaceutical settings will find the funnel’s reliability and ease of use essential for reproducible results and efficient workflow.

FAQ

What types of solvents can the funnel handle?

The borosilicate glass construction is compatible with most organic solvents, aqueous solutions, acids, and bases commonly used in laboratory settings. However, it is advisable to avoid highly concentrated hydrofluoric acid, which can etch glass.

Can the PTFE stopcock be cleaned with strong detergents?

Yes, the PTFE stopcock can be cleaned with standard laboratory detergents and rinsed with deionized water. For stubborn residues, a mild solvent soak followed by thorough rinsing is recommended.

Is the 19/26 plastic stopper reusable?

Absolutely. The stopper is designed for repeated use. After each experiment, simply clean it with an appropriate solvent, rinse, and allow it to dry before reinserting.

What is the recommended method for storing the funnel?

Store the funnel upright in a clean, dry cabinet away from direct sunlight and extreme temperature fluctuations. Using a protective cap or cover can further prevent dust accumulation.

Does the funnel come with a warranty?

EISCO provides a limited one‑year warranty covering manufacturing defects. Contact EISCO customer service with your purchase details for warranty claims or replacement inquiries.
