Ideal Vacuum Cube 1.5 mm Orifice Conductance Limiting Coupler Insert for 6 x 6 Cube Conductance Limiting Coupler Kit

This is a conductance limiting aluminum insert for the 6x6 Ideal Vacuum Cube 6 x 6 Conductance Limiting Coupler Kit (P108236). This insert has a 1.5 mm diameter orifice hole. An insert must be used with the conductance limiting coupler kit.

The conductance limiting coupler kit combined with an orifice insert allows two chambers to be held at different vacuum levels with a slow flow of gas between them. Due to the long path length of the orifice relative to the orifice diameter, the gas exits the lower pressure side as a tightly focused beam. Applications include calibration of precision valves and flowmeters, residual gas analysis, and molecular beam spectroscopy.

Orifice inserts for the Cube conductance limiting coupler kit are available with hole diameters of 0.5, 1.0, 1.5, and 2.0 mm.
