Dropping Funnel 500mL Lab Stand EISCO Glass Heavy Base Clamp

Description

Product Overview

The EISCO 500mL Dropping Funnel set is engineered to meet the rigorous demands of modern laboratory work while remaining accessible for educational settings. At its core is a cylindrical glass funnel crafted from industrial‑grade borosilicate 3.3 glass, offering superior chemical resistance and thermal stability. The funnel features an open top for easy loading and a PTFE key stopcock at the dispensing end, allowing precise control of flow rates. Supporting the funnel is a robust sheet‑metal base, powder‑coated to resist corrosion and finished with rubber feet to dampen vibrations. A stainless steel rod securely attaches the funnel to the base, adding structural integrity. Completing the system is a three‑finger extension clamp made from solid zinc die‑cast, with vinyl‑coated jaws that provide a slip‑free grip and a 360° swivel bosshead for flexible positioning. The assembled apparatus weighs approximately 3.75 pounds, delivering a balance of stability and portability ideal for a range of laboratory tasks.

Usage

This comprehensive setup is suited for a variety of environments, from high‑school chemistry classrooms to university research labs and even well‑equipped home laboratories. The funnel’s 500mL capacity makes it perfect for tasks such as transferring solvents, adding reagents to reaction vessels, and performing distillation preparations where controlled flow is essential. The heavy base and sturdy clamp ensure that the apparatus remains steady during prolonged operations, reducing the risk of spills or breakage. Whether you are conducting titration experiments, preparing solutions, or setting up a simple filtration system, the EISCO dropping funnel delivers reliable performance. Its ergonomic design also facilitates easy cleaning and maintenance, allowing quick turnaround between experiments.
