Description
Product Overview
The FSLAB 1000 ml borosilicate glass separatory funnel is engineered for demanding laboratory applications where precision, durability, and chemical resistance are paramount. Constructed from high‑grade borosilicate glass, the funnel resists thermal shock and corrosion from a wide range of solvents, acids, and bases. Its heavy‑wall design adds structural strength, reducing the risk of breakage during routine handling or when subjected to temperature fluctuations. The integrated PTFE stopcock provides a smooth, leak‑free flow control, while the 24/40 joint configuration ensures compatibility with standard laboratory glassware such as condensers, drying tubes, and receiving flasks. The funnel measures 17.09 × 7.91 × 6.06 inches and weighs 3.33 lb, making it easy to maneuver on a bench without sacrificing stability.
Usage
This separatory funnel excels in a variety of laboratory settings, from academic research labs to industrial quality‑control environments. It is particularly well‑suited for liquid‑liquid extraction, phase‑separation titration, and small‑scale distillation processes. The clear glass body allows technicians to monitor the interface between immiscible liquids, facilitating accurate collection of the desired phase. The funnel’s robust construction makes it a reliable choice for food‑testing laboratories where repeated exposure to acidic or basic solutions is common. Additionally, the PTFE stopcock’s chemical inertness ensures that no contamination occurs during prolonged use, preserving sample integrity across multiple experiments.
