Our MicroTight Unions Assembly is used specifically to easily connect capillary tubing together. True ZDV (Zero Dead Volume) allows two pieces of tubing to connect directly to each other using the included gauge and plug to ensure proper alignment. This allows for an uninterrupted fluidic path. It is for use with 1/32OD Tubing and includes (2) F-126S Fittings and (1) P-553 Gauge.
