2-Way Stopcock with Luer Connection, Female Luer Ends, PP Material, 100-Pack

Description

Product Overview

The 2‑Way Stopcock with female Luer connections from TODA Fluid Control is engineered for precise, bidirectional fluid management in demanding medical, laboratory, and research environments. Constructed from medical‑grade polypropylene (PP), the stopcock provides excellent chemical resistance, durability, and compatibility with standard sterilization procedures. Each unit measures 3 × 1.5 × 0.1 inches and weighs approximately 2.5 lb, offering a compact footprint that fits easily into tight instrument panels and fluid circuits. The design incorporates a 360‑degree rotation capability, allowing users to align the flow direction marker with the desired port without removing the component. Clear, engraved markings indicate the flow direction, reducing the risk of operator error and ensuring consistent performance across multiple setups. The stopcock’s female Luer lock ends guarantee a secure, leak‑free connection to syringes, catheters, and other Luer‑compatible devices, making it an ideal choice for applications ranging from drug dispensing to sample preparation. With a bulk pack of 100 units, laboratories can maintain an ample inventory for routine procedures, emergency replacements, and large‑scale studies, while benefiting from the cost efficiencies of bulk purchasing.

Usage

This 2‑Way stopcock is suited for a wide variety of settings where reliable fluid control is essential. In clinical laboratories, it enables precise dosing of reagents, controlled mixing of solutions, and safe handling of hazardous chemicals. Researchers conducting in‑vitro assays can use the stopcock to quickly switch between reservoirs, isolate reaction chambers, or purge lines without introducing contamination. In pharmaceutical manufacturing, the device supports sterile transfer of active ingredients, ensuring that each batch meets stringent quality standards. The stopcock also performs well in educational laboratories, where students learn fundamental techniques such as titration, filtration, and chromatography. Its robust PP construction tolerates repeated cycles of opening and closing, making it a durable component for long‑term experiments. Because the Luer connections are compatible with standard syringes and tubing, the stopcock integrates seamlessly into existing setups, reducing the need for additional adapters or custom fittings. The 360‑degree rotation feature simplifies alignment in cramped spaces, while the clear flow direction indicator helps users avoid accidental reverse flow, which could compromise experimental results or patient safety.

FAQ

How does the 2‑Way stopcock ensure a secure connection?

The stopcock features female Luer lock ends that engage with the corresponding male Luer connectors on syringes, catheters, and tubing. When twisted into place, the lock mechanism creates a tight seal that prevents leaks even under high pressure, providing a reliable connection for both low‑volume dosing and larger‑scale fluid transfers.

Can the stopcock be sterilized for reuse?

Yes. The polypropylene material is compatible with common sterilization methods, including autoclaving at 121 °C for up to 30 minutes. The design tolerates repeated cycles without degradation of mechanical performance, allowing the stopcock to be safely reused in sterile environments.

What is the advantage of the 360‑degree rotation feature?

The 360‑degree rotation allows the user to orient the flow direction indicator to match the layout of the fluid system without removing the stopcock. This flexibility simplifies installation, especially in cramped instrument panels or when integrating the stopcock into existing setups that have fixed port orientations.

Is the stopcock compatible with all syringe sizes?

The female Luer lock conforms to the standard 2.5 mm (0.1 in) Luer lock dimension, making it compatible with a wide range of syringe sizes from 1 mL up to 60 mL and beyond. This universal compatibility ensures that the stopcock can be used across many applications without the need for additional adapters.

What support does TODA provide after purchase?
