KSL1700XS 1700°C Compact Muffle Furnace with 1.7L Chamber, Pull-Down Door & 30-Segment Programmable PID Controller
The KSL1700XS furnace is designed for precise high-temperature annealing and sintering tasks in research and dental laboratories, where controlled thermal processing of small to medium samples is required. Its compact 1.7-liter chamber accommodates materials up to 1700°C, enabling advanced heat treatments such as material densification, phase transformations, and ceramic firing with reliable temperature uniformity.
This model features a pull-down door that simplifies sample loading and unloading while minimizing heat loss. The furnace incorporates a highly efficient 1800-grade fiber alumina insulation with a reflective coating to reduce energy consumption, maintaining a case temperature below 60°C through a double-layer steel structure and integrated air cooling fan. A built-in gas inlet and venting port allow controlled atmosphere treatments, expanding its versatility for specialized processes.
