Multiport Cluster ConFlat (CF) Flanges



Critical for UHV and XHV experimentation, optics, and sputtering techniques, multiport flanges are an essential tool for processes requiring several components such as viewports, pressure gauges, and sputter sources to be mounted to a single chamber. With over 50 years of experience serving national labs, private labs, universities, and other research facilities, ANCORP has created standards for the most common configurations to improve customer experience and lead time. Standard ConFlat (CF) multiport cluster flanges are highly customizable and available in three configurations: multiport angled-in, multiport straight-in, and cluster flange angled-in.

In order from left to right: multiport straight-in, multiport angled-in, cluster angled-in

Configuration Benefits

Straight-in configurations have flush-mounted mini-flanges which allow greater ease of use with motion manipulators and other system accessories requiring user maneuverability. Cluster angled-in and multiport angled-in orientations are both manufactured with ports angled in towards a focal point within the chamber. This construction allows for mounted components to be directed towards the desired target within the chamber.
