For general heating, 22 x 10 x 10 cm Chamber 900 °C Muffle Furnace is an excellent choice for laboratories. The mild steel construction helps it maintain even temperatures throughout its chamber, which is made from non-reactive mild steel and can withstand temperatures up to 900° C. The integrated doorframe makes it ideal for use in research facilities where the muffle furnace needs to be moved often; if you need a more permanent setup, the frame also comes with removable side panels that let you bolt it into place.
