Description
Product Overview
Junyue’s Sterile Luer Lock 3 Way Stopcocks are engineered to meet the rigorous demands of modern medical and laboratory environments. Each stopcock features a precision‑machined Luer lock interface that guarantees a tight, leak‑free seal, even under high‑pressure fluid dynamics. Constructed from high‑grade, autoclavable polymer, the components resist chemical degradation and maintain dimensional stability after repeated sterilization cycles. The 3‑way configuration enables versatile flow control, allowing users to direct fluids between three separate channels with a single, intuitive turn of the valve. Packaged individually, the 50‑piece set simplifies inventory management and ensures that each unit remains sterile until the moment of use.
Designed with both performance and ergonomics in mind, the stopcocks incorporate a smooth‑operating rotary knob that provides tactile feedback, reducing the risk of over‑turning and ensuring precise positioning. The compact form factor fits seamlessly into standard Luer‑compatible tubing assemblies, making it an ideal replacement for older, less reliable components. Detailed specifications include a 2.5 mm Luer lock thread, a pressure rating of up to 2 bar, and compatibility with a wide range of fluids, from aqueous solutions to viscous reagents. This combination of durability, accuracy, and ease of use positions the Junyue stopcocks as a trusted solution for critical applications.

Usage
These stopcocks excel in a variety of settings, including clinical laboratories, research facilities, pharmaceutical manufacturing, and point‑of‑care diagnostic stations. In a clinical lab, technicians can employ the 3‑way design to quickly switch between sample collection, reagent addition, and waste disposal without interrupting workflow. In pharmaceutical production, the leak‑free seal helps maintain sterility and prevent cross‑contamination during batch processing. The robust construction also makes the stopcocks suitable for field use in mobile health units, where durability and reliability are paramount. Whether handling blood, culture media, or chemical reagents, the Junyue stopcocks provide consistent performance across a broad temperature range, from refrigerated storage to elevated incubation conditions.
Because each unit is individually sealed, users can confidently open a single stopcock without compromising the sterility of the remaining inventory. This feature is especially valuable in high‑throughput environments where rapid access to sterile components is essential. The intuitive operation reduces training time for new personnel, while the clear labeling on the valve face aids in quick identification of flow direction, minimizing the chance of user error. Overall, the stopcocks support efficient, safe, and reproducible fluid handling across diverse applications.
