Labware 1000ml Glass Separatory Funnel with Stopcock and Ringstand

Description

Product Overview

The Labware 1000ml glass separatory funnel is a premium laboratory instrument engineered for precise liquid‑liquid extraction. Constructed from high‑grade borosilicate glass, the funnel offers exceptional chemical resistance, ensuring durability even when exposed to aggressive solvents and acids. The integrated glass stopcock provides smooth, leak‑free operation, allowing users to control the flow of liquids with fine precision. Complementing the funnel is a sturdy steel ringstand, electroplated for corrosion resistance, which securely supports the funnel during extended use. Dimensions of 8 x 8 x 20 inches make the unit compact enough for benchtop storage while providing ample capacity for large‑scale separations. The rod, measuring 20 inches in length with a 3/8‑inch diameter, offers a comfortable grip and reliable leverage, reducing fatigue during repetitive tasks. Detailed specifications include a stamping steel base (8″ x 5″), an outer ring diameter of 4 inches, and a robust construction that meets the rigorous standards of academic, industrial, and quality‑control laboratories.

Usage

This separatory funnel excels in a variety of environments where accurate phase separation is critical. In academic chemistry labs, it supports routine teaching experiments, such as extractions of organic compounds, allowing students to observe clear layer separation and practice proper technique. In research facilities, the 1000ml capacity accommodates larger sample volumes, making it ideal for synthesis purification, natural product isolation, and solvent recovery processes. Industrial quality‑control labs benefit from the funnel’s reliable performance when testing product purity or conducting solvent‑based extractions on a production scale. The glass stopcock’s fine control enables precise decanting of the lower phase without disturbing the upper layer, while the ringstand provides a stable platform that minimizes the risk of accidental spills. Whether used on a standard laboratory bench, a fume hood, or a dedicated extraction station, the funnel’s ergonomic design and durable materials ensure consistent results across a wide range of applications.
