“The compactness of the instrument makes for flexible and convenient placement in the lab. With a tiny footprint, it sits on a table or desk accompanied by only a laptop. In addition, bilayers are painted 'blind' with a teflon wand supplied by Nanion without observing the partition through a microscope.

Prof. Dr. Chris Miller - Case Study about the Orbit mini
"Contrary to my initial expectations, the Orbit mini (red arrow) has performed exceptionally well for
our application, with vastly improved signal-tonoise characteristics over our best recordings on the home-built system."
entire support-package of microscope, illuminator, Faraday cage, vibration-table, and rig-rack is eliminated. The acquisition software is intuitive and robust, and the data can be stored in formats readable by the Axon analysis programs that we routinely use. Moreover, the four electrically independent holes in the chip-partition means that four bilayers can be monitored simultaneously, thus quadrupling the probability of catching a clean single channel to record. This represents a significant, practical boost in experimental efficiency.”

Orbit 16 and Orbit Mini
This webinar covers the use of the lipid bilayer platforms from Nanion: the Orbit16 and the Orbit mini for characterization of membrane proteins like ion channels, bacterial porins and biological nanopores. Both bilayer systems support high quality low noise recordings, but differ in throughput capabilities and experimental features. The Orbit16, introduced in 2012 is a device for efficient formation of 16 lipid bilayers simultaneously, allowing for parallel bilayer-reconstitution of ion channels and nanopores.
