PYROFLASKS are manufactured using advanced proprietary techniques which provide “k” coefficient levels unattainable with conventional insulations but in a compact design that maximizes space available for the electronics payload. The high efficiency of these instrument packages is a result of the features belowat right:


  • Austenitic stainless steels standard, other materials available on request
  • Concentric thin wall tube assembly
  • Annular space between tubes evacuated at elevated temperature – virtually eliminates gas conduction
  • Multi-layer reflective insulation to minimize radiation heat transfer
  • Evacuation tube cold welded for permanent high vacuum seal
  • Low conductivity internal support to maintain inner tube concentricity and still allow thermal expansion
