Laboy Glass 10mL Separatory Funnel with 14/20 Joint and PTFE Stopcock

Description

Product Overview

The Laboy 10mL glass separatory funnel is engineered for laboratory professionals who demand accuracy, durability, and ease of use in liquid handling tasks. Constructed from high‑quality borosilicate glass, the funnel offers excellent chemical resistance and thermal stability, allowing it to withstand a wide range of solvents, acids, and bases without compromising structural integrity. The pear‑shaped body promotes smooth flow and minimizes turbulence during phase separation, while the graduated markings provide clear visual cues for volume measurement. A precision‑machined 14/20 joint at the top ensures a tight, leak‑free connection to standard laboratory glassware such as condensers, adapters, and receiving flasks. The integrated 2mm PTFE stopcock delivers precise control over liquid discharge, reducing the risk of splashing and enabling fine adjustments during extraction or washing steps. This model, identified as LBSF47001, has been a reliable choice for research institutions, teaching laboratories, and industrial settings since its introduction in February 2020. Its design balances ergonomic handling with robust performance, making it a versatile tool for organic synthesis, analytical chemistry, and process development.

Usage

The separatory funnel excels in applications that require the separation of immiscible liquids, such as liquid‑liquid extractions, solvent washes, and phase separations in synthetic chemistry. Its 10mL capacity is ideal for small‑scale reactions, analytical sample preparation, and educational demonstrations where precise volume control is essential. Users can easily attach the funnel to a standard 14/20 joint apparatus, allowing seamless integration into existing glassware setups. The PTFE stopcock provides smooth operation even after repeated use, ensuring consistent performance over the lifespan of the instrument. In addition to organic synthesis, the funnel is suitable for environmental testing, pharmaceutical analysis, and quality control laboratories where accurate separation of aqueous and organic phases is required. The clear glass construction enables visual monitoring of the interface between layers, facilitating timely decision‑making during experimental procedures. Proper cleaning after each use, combined with the chemical resistance of both glass and PTFE components, helps maintain the funnel’s clarity and functionality for long‑term use.
