NMR Air Compressor

For 60 & 90 MHz NMR sample spinning and eject

The AS-1 NMR air compressor is a perfectly matched air compressor with membrane drying technology for all 60 & 90 MHz NMR instruments which require compressed air for sample spinning and eject.
The patented membrane drying technology dries the spin air to a dew point of 0 °C which allows for continuous use  and more reliable spinning even in humid environments.

Key Features:

  • Perfectly sized diaphragm pump for quiet operation
  • Brushless DC motor for long life
  • Easy routine maintenance for diaphragm replacement after several years
  • Membrane Drying technology for reliable spinning and continuous use
  • Zero vibration eliminates sidebands
  • Compact design for easy sighting
  • Electronic control eliminates mechanical valves
  • Low power consumption

The Alegre Science NMR Air Compressor has provided a quiet and reliable source of air for spinning, injecting and ejecting sample tubes from our 60MHz  NMR unit. The AS-1 makes it possible for triple the throughput of student data.”

“I love my NMR Air Compressor! The original compressor I had with my NMR was a much louder compressor and was often unreliable. I teach first year organic chemistry at Sierra College in California and it was very frustration to have down time on the instrument, caused by students spending 10-15min+ trying to get their samples to spin. Donald Bouchard made me a prototype of the spinner air source and controller, I was able to hook it up myself, with his instructions, and have been very glad to have little to no down time for my students. The new air source is nowhere near as loud. Because my student can get their samples spinning quickly and reliably, they are able to run more samples throughout the semester. I even have time now to let them run 2D spectra (COSY, DEPT and HETCOR). I have one NMR and approximately 15 students per lab section.“ Mark S.
