Separating Funnel 50ml Pear Shaped by EISCO with 14/23 Plastic Stopper

Description

Product Overview

The EISCO 50ml pear‑shaped separating funnel is constructed from premium borosilicate glass, a material renowned for its superior thermal stability, chemical resistance, and clarity. This funnel features a compact 2.25‑inch diameter and an 8‑inch height, providing a convenient footprint while maintaining sufficient volume for routine laboratory separations. The interchangeable 14/23 plastic stopper offers a secure, leak‑free seal, and the integrated glass stopcock delivers smooth, precise control of liquid flow during phase separation. The design is ungraduated, allowing users to focus on qualitative separation rather than precise volume measurement, which is ideal for small‑scale extractions, acid‑base washes, and teaching demonstrations. The robust construction ensures the funnel can withstand repeated use, cleaning cycles, and exposure to a wide range of solvents without compromising integrity.

Usage

This separating funnel is suited for a variety of laboratory applications where reliable phase separation is essential. In organic chemistry labs, it excels at separating immiscible liquids such as aqueous and organic phases during extraction procedures, allowing chemists to isolate desired compounds efficiently. The funnel is also valuable in analytical chemistry for sample preparation, where precise removal of supernatant liquids is required before analysis. Educational settings benefit from its clear glass construction, which enables students to visually track the separation process, reinforcing fundamental concepts of density differences and solubility. The 14/23 plastic stopper is compatible with standard laboratory clamps and stands, making it easy to integrate into existing setups. Whether used for routine acid‑base titrations, solvent recovery, or small‑scale synthesis, the funnel provides consistent performance and ease of handling.

FAQ

What is the capacity of the funnel?

The funnel holds up to 50 milliliters of liquid, making it ideal for small‑scale extractions and laboratory demonstrations.

Can the stopper be replaced with a different size?

Yes, the funnel uses a standard 14/23 stopper thread, allowing you to replace the plastic stopper with any compatible 14/23 stopper, including glass or PTFE options, to suit specific experimental needs.

Is the borosilicate glass compatible with strong acids and bases?

Borosilicate glass is highly resistant to most acids and bases commonly used in laboratory settings, including hydrochloric acid, sulfuric acid, and sodium hydroxide, though extreme concentrations should be handled with care.

How should I clean and maintain the funnel?

After use, rinse the funnel with appropriate solvents to remove residues, then wash with warm soapy water. Rinse thoroughly and allow to air‑dry. For stubborn residues, a gentle soak in a compatible cleaning solution followed by a thorough rinse is recommended.

What is the recommended method for storing the funnel?

Store the funnel in an upright position, preferably in a dedicated glassware cabinet, with the stopper removed to prevent pressure buildup and to allow airflow, which helps maintain the integrity of the glass and stopper.
