Capillary tubing offers 'unparalleled' flow control

Loose capillary internal diameter tolerances can result in unwanted dead-volumes, band broadening, inconsistent flow rates, and imprecise dosage delivery. Drawn from high purity synthetic fused silica preforms,the VS flexible fused silica capillary tubing consistently delivers superior performance and optimal flow control with an internal diameter tolerance down to ±1µm for internal diameters as large as 50µm. This improves dosage precision, yields highly reproducible gas and fluid delivery rates and decreases variance of system dead-volumes in critical applications such as nano-flow liquid chromatography and mass spectroscopy, among other advantages in virtually any application using capillary tubing.

The industry-standard outer diameter dimensions of Polymicro Technologies' VS capillary tubing easily interface with existing connector technology. Synthetic fused silica capillary properties allow tubing to be cut or cleaved to length. Rated for operation up to 350°C, a durable polyimide outer coating resists chemical damage and abrasion for better mechanical flexibility and protection during use and handling.

Joe Macomber, Product Manager, Molex, comments: “Laboratory professionals need the most reliable capillary tubing with tight tolerances for repeatable flow control. VS flexible fused silica capillary tubing consistently holds tight internal diameter tolerances to achieve the most precise flow control in the industry. Polymicro Technologies VS capillary tubing can be tailored to a customer’s most stringent specifications to boost design efficiency and productivity in the lab."
