Hynec 3-Way Luer Lock Stopcock 4.0mm Polycarbonate Valve 20-Pack

Description

Product Overview

The Hynec 3-Way Luer Lock Stopcock is engineered to meet the rigorous demands of modern laboratory work, educational settings, and hobbyist projects. Constructed from high‑quality polycarbonate and reinforced with high‑density polyethylene, the valve offers exceptional chemical resistance and mechanical durability. Each stopcock features a 4.0mm (0.16 inch) inlet and outlet size, compatible with standard Luer lock tubing, ensuring a secure, leak‑proof connection that can withstand repeated cycles of opening and closing. The compact dimensions—1.16 x 0.74 x 1.6 inches—allow for easy integration into tight spaces, while the transparent body provides visual confirmation of fluid flow. The package includes 20 individually packaged stopcocks, each inspected for quality and ready for immediate use in a variety of fluid handling applications.

Usage

Designed for versatility, this three‑position stopcock excels in a wide range of environments. In academic laboratories, it enables precise control of reagents during titration, chromatography, and sample preparation, supporting both chemistry and biology curricula. Researchers in biomedical fields appreciate the secure Luer lock mechanism for handling sensitive fluids such as cell culture media, buffers, and diagnostic reagents, where contamination must be minimized. The stopcock also serves well in DIY and maker projects, including 3D printer filament extrusion systems, custom aquarium filtration rigs, and small‑scale photovoltaic testing setups where fluid flow regulation is critical. Its shut‑off capability allows users to isolate sections of a fluid circuit without removing tubing, simplifying troubleshooting and maintenance. Whether you are conducting high‑precision analytical experiments, building a prototype fluid delivery system, or teaching students the fundamentals of fluid dynamics, the Hynec stopcock provides reliable performance and ease of use.

Why Choose Us

Hynec Technology Limited has a reputation for delivering high‑performance scientific components that combine robust engineering with cost‑effective pricing. The 3‑Way Luer Lock Stopcock benefits from a rigorous quality control process that includes dimensional verification, leak testing, and material certification, ensuring each unit meets industry standards. Unlike many generic alternatives, our stopcock incorporates a dual‑material design—polycarbonate for clarity and strength, and high‑density polyethylene for added impact resistance—resulting in a product that resists cracking, crazing, and chemical degradation over extended use.

FAQ

What types of fluids can I use with this stopcock?

The stopcock is compatible with most aqueous solutions, organic solvents, and biological fluids that fit standard Luer lock tubing. Its polycarbonate construction resists many chemicals, but for highly aggressive acids or bases, verify compatibility with the specific fluid.

Can the stopcock be sterilized for biomedical applications?

Yes, the valve can be autoclaved at typical laboratory temperatures (up to 121°C) without compromising the integrity of the polycarbonate or the Luer lock threads, making it suitable for sterile environments.

How do I install the stopcock in my fluid system?

Simply insert the Luer lock tubing into the inlet and outlet ports, then turn the lock mechanism clockwise until it clicks securely. The transparent body lets you see fluid movement, and the three‑position lever lets you select flow, shut‑off, or reverse direction as needed.

Is the 20‑pack sufficient for larger projects?

The 20‑pack provides ample quantity for most laboratory setups, educational labs, and small‑scale prototype builds. For larger installations, bulk orders are available upon request, and Hynec can provide custom packaging to suit your project scale.

What warranty does Hynec offer on this product?

Hynec provides a one‑year limited warranty covering manufacturing defects. If you encounter any issues within this period, contact our support team for a replacement or refund, subject to the terms of the warranty.

Overall, the Hynec 3‑Way Luer Lock Stopcock combines reliable performance, versatile design, and robust construction to meet the needs of scientists, educators, and makers alike. Its ability to deliver precise fluid control while maintaining a simple, user‑friendly interface makes it an essential component for any fluid handling system. Whether you are setting up a new laboratory experiment, building a custom fluid circuit, or teaching the next generation of engineers, this stopcock offers the confidence and functionality required to achieve accurate and repeatable results.
