Hybrid Muffle Furnace 1200 C for Laboratory (6″x6″x6″, 3.3L)

PH L3/12 is a newly designed small benchtop hybrid muffle furnace (6″x6″x6″, 3.3L), which intergrates a quartz processing tube with a ss304 vacuum flange and a box chamber into one. The furnace can process different samples under atmosphere or vacuum condition with Tmax 1200 degree C. Hybrid muffle furnace is a cost-effective furnace in research labs and industrial.

Product Overview

Hybrid muffle furnace integrates a chamber muffle furnace and a tube furnace in one, compact, light weight, easy to operate. Designs with inlet and outlet ports on the quartz tube with sealing flange attached in the chamber. A compact hybrid muffle furnace could be used for materials heat treatment processing under atmosphere or vacuum condition at a max working temperature of 1200℃, applicable for material sintering, heating preparation of Li battery, Carbon, graphene materials etc.

Main Features
  • Tmax 1200℃
  • Hybrid muffle / tube furnace, dual purpose
  • One-end closed 2″ quartz tube, a tube block, and a corresponding sealing flange and pressure gauge
  • Multiple atmosphere processes in a single cycle are possible
  • Fiber-insulated chamber for maximum temperature stability and uniformity
  • Embedded heating elements on 3 sides give an improved temperature gradient
  • Flanges support provides better sealing and longer tube life
  • Type N thermocouple. Equips two pcs, one for temperature testing, the other for protection
  • CE certified, standard
Safety Measures
  • Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.
  • Overheat protection shuts down the furnace if temperature is outside of acceptable range (refer to controller’s manual) or when the thermocouple is broken or malfunctions.
  • Power failure protection resumes furnace operation right after the point of failure when power is reestablished.
  • Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot
