  • Vacuum lid with rubber sealing gasket
  • Gas connection with quick-release coupling with 3/8 inch hose sleeve
  • Charge thermocouple type K
  • Pull lug of model N 30/45 HA - N 120/85 HA
  • Made of heat-resistant alloys: 450 °C - 304 (AISI)/(DIN material no. 1.4301), 650 °C - 321 (AISI)/(DIN material no. 1.4541) or 850 °C - 309 (AISI)/(DIN material no. 1.4828)

Additional Equipment
