About

11-BM has a dedicated Cyberstar Hot Gas Blower. This can be used to heat small diameter capillary samples from ambient temperature to ~ 950 °C

About

Temperature Range and Ramp Rate.

  • ambient temperature to ~ 950 °C
  • Max ramp rate on heating & cooling is 5 deg C/min (300 C/hour)

Users should plan experiments to incorporate these heating and cooling ramp times.
