Our MicroTight Unions are designed to easily connect capillary tubing together. They offer True ZDV (Zero Dead Volume) allowing two pieces of tubing to connect directly to each other using the included gauges and plugs to ensure proper alignment. This allows for an uninterrupted fluidic pathway.
Our MicroTight Union Assembly is used specifically to connect capillary tubing together. It features a 0.015 inches thru-hole which adds only a small amount of additional flow-path volume to help ensure proper chromatographic results.
