JK-1800 High Temperature Vacuum Muffle Furnace is the most cost effective bench-top high temperature muffle furnace.  The furnace consists of high quality alumina fiber brick and MoSi2 heating elements with chamber of 24"x24"x24", and temperature is controlled by high precision digital controller with accuracy +/-1C and 51 segments programmable up to 1800C or 3092F.

It is an ideal tool for materials annealing and sintering in your research laboratory.

.

JK-1800 Vacuum Muffle Furnace Features:
1) High quality super MoSi2 heating elements serve as heating element and can be heated up to 1800C.
2) High quality ceramic fiber board with ZrO2 Liner. 
3) Effective heated chamber: 20"x20"x20".
4) The furnace temperature is controlled by precision SCR (Silicon Controlled Rectifier) digital controller with accuracy +/-1C and 51 segments programmable up to 1800C.
5) Built in precision digital temperature controller is 51 segments programmable to control heating rate, cooling rate and dwell time. 
6) All accessories are included for immediate use, including:
--Stainless steel vacuum flange with needle vacuum connector and two needle valves are installed on top.
--Heavy duty high speed mechanical pump and stainless steel included vacuum pipe are included.
--Compact Digital Vacuum Gauge & Controller
--Double Step Rotary Vane Vacuum Pump
--PID automatic controller
