DOOWON 50PCS 3-Way Stopcock with 25cm Extension DEHP-Free Fitting

Description

Product Overview

The DOOWON 50‑piece 3‑way stopcock set is engineered for precise fluid management in both clinical and research environments. Each stopcock features a robust Luer‑type connection that guarantees a leak‑free seal, while the 25 cm (10‑inch) extension provides added flexibility for complex tubing arrangements. Constructed from high‑grade, DEHP‑free polymer, the components are non‑pyrogenic and meet stringent biocompatibility standards, making them safe for direct contact with blood, saline, and other critical fluids. The set includes fifty individual stopcocks, each calibrated to deliver smooth rotation and reliable shut‑off, reducing the risk of accidental flow interruption during procedures. With a compact design that fits easily into standard instrument trays, the stopcocks are ideal for use in infusion pumps, dialysis machines, surgical kits, and research apparatus where accurate fluid direction control is essential. The material selection also offers excellent chemical resistance, allowing the stopcocks to handle a wide range of reagents, including acidic, basic, and organic solutions, without degradation. This durability extends the service life of each unit, providing cost‑effective performance over many years of operation. Additionally, the transparent housing enables quick visual inspection of the internal flow path, helping users verify proper assembly and detect any potential blockages before they affect the procedure.

Usage

Designed for a wide range of applications, this stopcock collection serves clinicians, researchers, and technicians who require dependable fluid routing. In hospitals, the stopcocks are commonly employed to manage intravenous lines, connect medication reservoirs, and facilitate rapid switching between multiple infusion sources. Laboratory scientists use them to control reagent flow in chromatography systems, microfluidic devices, and custom‑built experimental rigs. The 25 cm extension allows users to bridge gaps between equipment without compromising sterility, and the DEHP‑free composition ensures that sensitive assays remain uncontaminated. Whether you are setting up a bedside infusion protocol, configuring a bench‑top analytical instrument, or assembling a portable diagnostic kit, the stopcocks provide intuitive operation and consistent performance. The ergonomic design of the rotating knob offers tactile feedback, enabling precise adjustments even when wearing gloves. This feature is particularly valuable in high‑stress environments such as emergency rooms or field hospitals, where rapid yet accurate fluid control can be critical. The stopcocks also integrate seamlessly with standard tubing sizes ranging from 1 mm to 6 mm inner diameter, offering versatility across a broad spectrum of devices. For research applications that demand reproducibility, the consistent torque and flow characteristics of each stopcock help maintain experimental integrity, reducing variability caused by equipment inconsistencies.

FAQ

What materials are the stopcocks made from?

The stopcocks are constructed from a high‑grade, DEHP‑free polymer that is non‑pyrogenic and meets medical‑device biocompatibility standards.

Can the stopcocks be sterilized?

Yes, they are compatible with standard sterilization methods such as autoclaving and ethylene oxide treatment, allowing reuse in sterile environments.

Is the 25 cm extension interchangeable with other lengths?

The extension is designed specifically for the included stopcocks, but additional extensions of compatible dimensions can be purchased separately to suit different setup requirements.

How many stopcocks are included in the package?

The set contains fifty individual 3‑way stopcocks, providing ample supply for large‑scale clinical or laboratory operations.

What is the warranty period for this product?

DOOWON offers a one‑year limited warranty covering manufacturing defects, backed by responsive technical assistance.

Beyond the core features highlighted above, the DOOWON 3‑way stopcock set is designed with a focus on long‑term reliability. The polymer matrix is engineered to resist cracking, crazing, and discoloration even after repeated cycles of sterilization and exposure to aggressive chemicals. This resilience translates into a lower total cost of ownership, as users can rely on the same set of stopcocks for multiple procedures without the need for frequent replacement. The ergonomic knob is molded from a slip‑resistant material that maintains its grip under wet or oily conditions, ensuring that precise adjustments can be made quickly and confidently. For institutions that operate under strict accreditation standards, the product’s documented compliance with ISO 10993‑1 (biological evaluation of medical devices) and USP (plastic packaging) provides an additional layer of assurance.

In practice, the stopcocks excel in scenarios where rapid fluid redirection is required. For example, during a multi‑drug infusion, clinicians can use the three ports to switch between medication lines without interrupting the primary infusion, thereby maintaining therapeutic continuity. In a research laboratory, the same three‑port configuration enables the creation of a simple mixing manifold, allowing two reagents to be combined on‑the‑fly before entering a detector. The 25 cm extension minimizes the need for additional connectors, reducing dead volume and potential sites for contamination. Moreover, the clear housing of each stopcock makes it easy to monitor the position of the internal valve, providing visual confirmation that the correct pathway is engaged.

Customer feedback consistently highlights the ease of use and reliability of the DOOWON stopcocks. Users report that the smooth rotation eliminates the “clicky” feel often associated with lower‑quality components, which can lead to over‑tightening and damage. The consistent torque across all units ensures that training time is reduced, as staff can quickly become proficient with the device. Additionally, the DEHP‑free formulation addresses growing concerns about plasticizers leaching into patient fluids, a factor that is increasingly scrutinized by hospital procurement committees.

From a logistical perspective, the packaging of the 50‑piece set is optimized for both protection and convenience. Each stopcock is individually sealed in a sterile pouch, allowing for selective use without exposing the entire set to the environment. The outer box includes a detailed inventory list, making it simple to verify that all components are present upon receipt. For bulk purchasers, DOOWON offers volume discounts and the option to customize packaging with institutional branding, further streamlining the supply chain.

In summary, the DOOWON 50‑piece 3‑way stopcock set combines high‑performance materials, thoughtful engineering, and comprehensive support to meet the demanding needs of modern healthcare and scientific research. Its DEHP‑free, non‑pyrogenic construction safeguards patient health, while the versatile 25 cm extension and reliable Luer fittings provide the flexibility required for a wide array of applications. Backed by a robust warranty and a reputation for quality, this stopcock set is a prudent investment for any organization seeking to enhance fluid control capabilities while adhering to the highest safety standards.
