Thistle Funnel with Rotaflow Stopcock

A Thistle Funnel with Rotaflow Stopcock is a specialized piece of laboratory glassware that combines the features of a thistle funnel and a rotational flow control stopcock. The thistle funnel is designed with a long shaft and a funnel-like reservoir at the top to add small volumes of liquid accurately to a system. The attached Rotaflow stopcock is a screw-type valve that allows precise control of liquid flow through the funnel, enhancing the utility and control during experiments involving liquid transfer or separation.

This funnel is made from high-quality borosilicate glass (Boro 3.3) ensuring chemical resistance, mechanical strength, and thermal stability. It is commonly used in chemistry and biology labs for tasks such as controlled liquid addition, separation of liquid mixtures, and purification processes. The Rotaflow stopcock mechanism is valued for its durability, ease of operation, and ability to regulate flow accurately.

Together, this combination makes the device ideal for controlled reagent handling and precise flow management during laboratory procedures
