Antique 100cc Irrigation Syringe – Functional Two-Way Stopcock & T-Handle – c. 1930. A formidable and mechanically impressive example of interwar surgical engineering. This large-capacity medical syringe features a heavy-duty barrel housing the glass inner, precision-graduated from 25 to 100cc. Designed for the efficient movement of large fluid volumes, it is equipped with a classic ergonomic T-handle for maximum leverage. The standout feature of this instrument is the integrated two-way bypass nozzle (stopcock). The control lever remains in smooth, working condition, allowing the practitioner to switch seamlessly between aspiration and irrigation without disconnecting the syringe—a vital feature for procedures such as thoracentesis or continuous bladder wash. Housed in its original fitted metal sterilisation tin, this is a complete, high-grade professional archive piece for the serious medical historian. Condition Report: Excellent mechanical condition. Both the main plunger and the two-way nozzle lever operate smoothly and freely. The plating is bright with minimal age-authentic wear. Graduations are crisp and legible. The original tin case is structurally sound and presents well, one side of one retaining clip is present but detached.
