So, read on to discover how you can find the right muffle furnace for your needs as per Bangkok Underground.


Consider Your Application


Don't make the mistake of buying a muffle furnace without considering your application. How do you intend to use your muffle furnace? Determining the processes you want your muffle furnace to serve will help you choose an ideal unit for your specific needs. Muffle furnaces can suit various applications, including:

  • Environmentally testing
  • Material research
  • Alloying 
  • Ashing
  • Heat Treatment


Think About the Operating Temperature Range


Apart from the application, you should also take your time to think about the operating temperature range. While you are at it, find out how long it takes for the muffle furnace you have in mind to reach maximum working temperature. Also, get to know about the rise time. Typically, the heating elements determine the maximum operating temperature, so take your time to look at that. 


Factor in the Subject Material


Muffle furnaces are used across a range of applications and industries. So, it helps to consider the subject material you want to work on before buying a muffle furnace. When you choose the wrong muffle furnace, you risk damaging the samples.


While looking at the samples, it would also be best to consider the crucible size. You don't want to buy a more undersized or oversized crucible. Remember to factor in the temperature too.


Check the Input Voltage


Finally, you should check the input voltage to choose the right muffle furnace. Typically, muffle furnaces have power sources ranging from around 110 VAC to 220 VAC. The actual power source range varies from one furnace type to another. You can check the label to determine the exact power source range requirements.
