LabGlass European Style 4 Neck Flask 250 ml 24/40 STJ with #7 Thread

The LabGlass 6961-39 European Style 4 Neck Flask is a specialized, multi-purpose reaction vessel used for complex chemical syntheses. This flask has a capacity of 250 mL and features four necks with a combination of standard taper joints and a threaded port. The European Style refers to a specific geometry of the necks, often with the side necks angled to provide better clearance for apparatus. One of the side necks has a #7 thread. This threaded port is designed to accept a specific type of fitting that allows for a gas-tight seal without the need for grease. This is particularly useful for attaching probes or tubing for inert gas lines.

Used, in great condition.
