Zymo Research S7001 One-Way Luer-Lock Clear Stopcock (Pack of 20)

Description

Product Overview

The Zymo Research S7001 One-Way Luer-Lock Clear Stopcock is engineered for high‑precision fluid handling in both laboratory and industrial settings. Constructed from chemically resistant clear polymer, the stopcock allows users to visually confirm the presence and flow of liquids, reducing the risk of contamination and improving workflow efficiency. Each unit features a secure Luer‑Lock connection that prevents accidental disconnection under pressure, while the one‑way valve design ensures unidirectional flow, protecting downstream equipment from back‑pressure. The pack includes 20 identical stopcocks, each weighing just 2.47 ounces and fitting within a compact package measuring 17.78 × 12.7 × 2.54 inches, making storage and inventory management straightforward. Designed and manufactured in the United States, the S7001 meets rigorous quality standards and is compatible with a wide range of tubing diameters and laboratory apparatuses, from simple syringe setups to complex vacuum manifolds.

Usage

These clear stopcocks excel in environments where precise fluid control and visual monitoring are critical. In research laboratories, they are ideal for chromatography, sample preparation, and cell culture applications where maintaining sterility and preventing cross‑contamination are paramount. In industrial contexts, the S7001 serves as a reliable component in pneumatic and hydraulic systems, vacuum manifolds, and process control lines, especially when dealing with corrosive or sensitive chemicals. The one‑way valve mechanism safeguards downstream pumps and detectors by eliminating reverse flow, while the transparent housing enables quick detection of bubbles, particulates, or leaks. Users ranging from graduate students to seasoned engineers appreciate the intuitive installation—simply twist the Luer‑Lock fitting until secure—and the low maintenance requirements, as the polymer material resists degradation from most solvents and cleaning agents.
