Needles & Couplers

Explore our collection of Needle & Coupler fittings, designed for microfluidic systems to ensure precise fluid delivery. These components provide secure connections, ensuring leak-free performance particularly vital for injecting or withdrawing fluids. With compatibility across a range of tubing ID from 0.5 mm to 1.6 mm, you can use these fittings in various primary applications, such as biomedical research and chemical analysis.

While blunt-end needles are widely used to connect a syringe to a soft-walled tubing, couplers are very useful to interface a PDMS chip to a tubing.

Built from high-grade materials like Methacrylate Photopolymer Composite, PP, PTFE, and Stainless Steel, these fittings offer exceptional chemical resistance and durability. They deliver minimal dead volume and maintain high-pressure tolerance, ensuring consistent flow control. Simple installation offers seamless compatibility with different tubing types, microfluidic chips, devices, and connection systems.

Choose our Needle & Coupler fittings to enhance precision, efficiency, and reliability in your microfluidic setups. Experience secure and durable performance for all your critical fluid control needs.
