This Jeol 5 mm tunable NMR probe (GX-400 HX5, model G40HX5) is designed for use on Jeol 400 MHz spectrometers with an HX-style observe/broadband configuration. It supports 1H observation with a tunable broadband X-channel suitable for common nuclei such as 13C, 31P, etc., adjusted via the integrated obs/tune and TR-1 controls. Connectors, body, and coil interfaces are present as shown, and users should review the photos for exact configuration details and cosmetics.
