VARIAN UNITY 500

The specifications from the manufacturer's quote are given below. NOTE: Only the console specifications are given, as the magnet was part of a General Electric GN500 spectrometer.

UNITY 500 NB NMR CONSOLE

  1. UNITY™ 500 NB High-Resolution FT NMR Console:
    • Channel 1: Fully broadband (6-530 MHz) rf source with 0.5° phase shifts

    • Channels 1 and 2 are capable of observe or decouple functions
    • 64-dB computer controlled attenuation of the rf input provided for channels 1 and 2
    • System amplifiers: 50-W 1H/19F linear amplifier, 300-W broadband linear amplifier
    • 2H fully automatic internal lock
    • 25-ns resolution pulse sequence controller
    • 16-bit ADC, 100-kHz spectral width
    • 2-Mbyte 32/16-bit acquisition computer and intelligent host interface
    • Automation of lock, shim, phase, gain, sample spin, and eject/insert
    • UNITY™ worktable
    • High stability variable temperature unit (-150°C to +200°C computer controlled, and 0.1°C temperature stability from -4°C to 60°C, preconditioning of laboratory air supply may be required
    • VNMR host and acquisition software and licenses.
    • Does not include Sun host computer
    • THIS IS A REFURBISHED UNIT AND SUBJECT TO AVAILABILITY
      Used Unit and Sold As Is
