Hynec 2-Way Luer Lock Stopcock 4.0mm EO Sterilized Valve 20 Pack

Description

Product Overview

The Hynec 2-Way Luer Lock Stopcock is engineered for precision fluid handling across a wide range of scientific and educational environments. Constructed from high‑grade polycarbonate and high‑density polyethylene, the valve offers exceptional chemical resistance and mechanical strength, ensuring long‑term reliability even under repeated sterilization cycles. Each stopcock features a 4.0 mm (5/32″) inlet/outlet size, compatible with standard Luer‑lock tubing, and a rotating male lock connector that provides a secure, leak‑proof seal. The EO‑sterilized finish guarantees that the valve is ready for immediate use in sterile applications, reducing preparation time and minimizing contamination risk.

Designed with a two‑position shut‑off mechanism, the stopcock allows users to quickly toggle between open and closed states, facilitating precise control over fluid flow during experiments, calibrations, or prototype testing. The ergonomic design of the rotating knob offers smooth operation with minimal torque, making it suitable for both delicate analytical procedures and more robust industrial testing. The compact dimensions—0.92 x 0.77 x 1.58 inches—and lightweight construction (0.064 ounces) enable easy integration into tight spaces and portable setups.

Each package contains 20 individually packaged stopcocks, providing ample inventory for multi‑step protocols, parallel testing, or classroom kits. The transparent and natural color options allow visual monitoring of fluid movement, while the optional blue variant adds a visual cue for specific applications. Detailed specifications, including model number HLL2WS-001-4.0MLEO, are printed on the packaging for quick reference, ensuring that users can match the component to their exact system requirements without ambiguity.

Beyond its core functionality, the Hynec stopcock incorporates a built‑in check valve that prevents backflow, enhancing safety in experiments involving reactive or hazardous chemicals. The barbed connectors are engineered to fit standard tubing diameters, eliminating the need for additional adapters and simplifying system assembly. This versatility makes the stopcock a valuable component for a broad spectrum of projects, from photovoltaic cell testing to biomedical assay development.

Usage

In laboratory settings, the Hynec 2‑Way Luer Lock Stopcock excels in applications such as titration, chromatography, and microfluidic device testing. Researchers can rely on its precise shut‑off capability to isolate reaction chambers, control reagent addition, and prevent cross‑contamination between samples. The EO‑sterilized surface ensures that the valve meets stringent aseptic standards required for cell culture, microbiology, and pharmaceutical assays.

Educational institutions benefit from the stopcock’s user‑friendly design, allowing students to explore fluid dynamics, chemical reactions, and instrumentation without the complexity of larger valve assemblies. Its compatibility with standard Luer‑lock syringes and tubing makes it an ideal teaching tool for hands‑on experiments in chemistry, biology, and engineering curricula.

For hobbyists and makers, the stopcock integrates seamlessly into DIY projects such as custom 3D‑printed fluid channels, aquarium filtration systems, and small‑scale pneumatic controls. The robust construction tolerates a variety of fluids, including water, solvents, and low‑viscosity oils, providing a reliable solution for prototype development and iterative testing.

Industrial technicians can employ the stopcock in field diagnostics, equipment maintenance, and rapid prototyping of fluid handling modules. Its compact footprint and quick‑connect features reduce downtime during system reconfiguration, while the leak‑proof design safeguards against costly spills or equipment damage.

FAQ

What tubing sizes are compatible with this stopcock?

The stopcock is designed for standard Luer‑lock tubing with an inner diameter of 4.0 mm (5/32″). It works with most commercially available Luer‑lock syringes and connectors, making it versatile for a wide range of fluid handling setups.

Can the stopcock be reused after sterilization?

Yes. The EO‑sterilized finish allows the valve to be autoclaved or chemically sterilized multiple times without degradation of performance. This reusability helps reduce consumable costs in high‑throughput laboratory environments.

Is the stopcock suitable for handling hazardous chemicals?

The polycarbonate body and high‑density polyethylene components provide excellent chemical resistance to many solvents, acids, and bases. However, for highly corrosive or reactive substances, users should verify compatibility with the specific chemical in question.

How does the shut‑off mechanism work?

Rotating the knob aligns an internal ball valve with the flow path, either opening the channel for fluid passage or rotating it to block the passage completely. This simple mechanical action offers reliable, repeatable control without the need for external power.

What warranty does Hynec offer for this product?

Hynec provides a one‑year limited warranty covering manufacturing defects and material failures. Should any issue arise within the warranty period, customers can contact support for a replacement or repair, ensuring continuous operation of their experiments.
