Button Heaters / Sample Heaters Overview

The new Thermic Edge Button Heater range offers a new approach to sample heating. The sample heater is very versatile enabling it to be easily upgraded, so that body or element materials can be easily changed to suit different heating requirements and environments.

The sample heater layout can be easily modified to allow for different sample mounting options. The heater is also very high performance, with high power density (enabling very fast ramp up times), with low mass body (reducing cool down times) and high thermal uniformity over the entire hot zone. The button heater is manufactured using different body and element materials to suit a wide range of applications and temperatures.

  • Standard one-inch hot zone (smaller available as a special)
  • Configurations for high vacuum, UHV, oxygen, air and corrosive environments
  • Temperatures up to 1400°C as standard (higher temperatures can be achieved on request)
  • Fast ramping and efficient
  • Supplied with suitable internal thermocouple to measure and control temperature
  • Supplied with M6 stud or flange mounted
  • Can be mounted in any orientation
  • High uniformity sample heating area as standard (<2%)
  • Fully customisable with complete bespoke solutions available
  • Stage mountable where rotation, Z-shift and RF or DC bias are required
  • In-vacuum and air side cable assemblies included
  • Built and tested in the UK
