Precise ID tolerances

Loose capillary ID tolerances can result in unwanted dead-volumes, band broadening, inconsistent flow rates, and imprecise dosage delivery. Drawn from high purity synthetic fused silica preforms, Polymicro Technologies VS flexible fused silica capillary tubing consistently delivers superior performance and optimal flow control with an ID tolerance down to ±1 µm for IDs as large as 50 µm.

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.
