Threaded Fittings

Threaded fittings are essential for microfluidic systems. These components ensure precision connections, providing leak-free and secure seals. Compatible with tubing sizes ranging from 1/32" to 1/8", they are ideal for primary applications such as biomedical diagnostics, chemical analysis, and lab-on-a-chip devices.

Made from materials like PEEK, PTFE, and Stainless Steel, these fittings are known for their chemical resistance and durability. They offer minimal dead volume, ensuring high-pressure tolerance and consistent flow control which is vital for accurate experiments and tests.

Easy to install, these fittings work seamlessly with different tubing types, microfluidic chips, and connection systems. Upgrade your microfluidic setup with our threaded fittings for unparalleled precision, efficiency, and long-lasting reliability.
