The bell-dewar construction includes alumina-dispersion-strengthened copper, a superalloy, a custom Cu-Ni alloy, Sn-bronze, and three braze alloys. A 30-hour vacuum bake-out at 620°C ensures long-term reliability.

  • Highly optimized, high temperature Si3N4 rotor/turbines have laser-machined blades with an integral shroud.
  • The Radial-inflow Si3N4 turbines minimize N2 gas consumption
  • Low-cost, boron-nitride sample cell inserts( inside Si3N4 rotor) for melting, reacting and outgassing situations.
