Duran ptfe 1/8″ 3port

Custom Duran PTFE 1/8″ 3-Port Cap for GL45 Media Bottles

Enhance your laboratory’s fluid management and experimental setups with our custom-engineered Duran PTFE 3-Port Cap. Designed specifically to fit standard GL45 thread reagent bottles, this advanced accessory provides an incredibly secure, multi-channel interface for transferring liquids and gases simultaneously.

In many complex research and industrial processes, a standard two-port system is simply not enough. The addition of a third port allows for more sophisticated and flexible operations. For instance, you can seamlessly configure a system to introduce a reagent, extract a sample, and maintain a continuous gas purge or vent line all at the same time. This custom-modified cap ensures your vessel remains a strictly closed system, protecting your sensitive contents from airborne contamination while preventing the escape of hazardous volatile compounds.

🔹 Key Product Highlights

• Triple Port Design (3 Ports): Precisely machined to accommodate three distinct 1/8″ O.D. tubes, allowing for complex fluid and gas routing (e.g., inlet, outlet, and venting).
• Leak-Proof Seal: Engineered to provide a highly secure airtight and watertight connection, ensuring zero leakage during demanding operational tasks.
• Superior Chemical Resistance: Manufactured from laboratory-grade PTFE (Polytetrafluoroethylene) and robust plastics, offering exceptional durability against aggressive chemicals and organic solvents.
• Reusable and Easy to Clean: The components can be easily disassembled for thorough cleaning, autoclaving, and sterilization, making it a sustainable and cost-effective choice.
• Universal GL45 Compatibility: Perfectly fits all standard GL45 laboratory media and reagent bottles, seamlessly integrating with your current glassware inventory.

🔹 Ideal Applications and Industries

• Laboratory & Research: Essential for analytical chemistry, biology, microbiology, and environmental testing applications.
• Fluid Dispensing & Aspiration: Ideal for controlled chemical dosing, automated sampling, and safely transferring hazardous liquids.
• Continuous Flow Systems: Perfect for setting up sparging systems, chromatography solvent reservoirs, or microreactor feed networks.
• Media & Buffer Storage: Safely connect culture media bottles directly to bioreactors or automated liquid handling units.
• R&D and Small-Scale Industry: Adaptable for custom prototype setups, mixing stations, and pilot-plant operations.

🔹 The Advantage of a 3-Port Closed System

Maintaining closed-system integrity is essential for accurate analytical results and workplace safety. When you utilize the Duran PTFE 3-Port Cap, you eliminate the need to repeatedly open caps for pressure equalization or adding solutions. The 1/8-inch precision-machined tubing connections offer a standardized and secure fit for fluoropolymer tubing, ensuring reliable performance under moderate system pressures.

The use of high-grade PTFE guarantees maximum chemical inertness, meaning no plasticizers or contaminants will leach into your critical samples. To verify if your specific aggressive solvents are suitable for this material, you can consult this comprehensive PTFE chemical resistance guide.

For a fully integrated and leak-free laboratory setup, we highly recommend pairing this multi-port cap with our durable lab glassware. Optimizing your closed-system workflows will lead to safer handling of chemicals and significantly more consistent experimental data over time.
