1000°C Compact Hybrid Furnace with Three Tubes & Flange ( 20ODx16IDx200L mm) - KSL-1100X-S3

In stock
Item Number: KSL1100XS3


KSL-1100X-S3 is a compact hybrid furnace that offers a 4"x4"x4" heating chamber to sinter samples in air, and three 16mm ID quartz tubes to process samples under high vacuum in high throughput.   it is an ideal furnace for preparing various samples in small quantities up to 1000oC under a controlled atmosphere.  In addition.  the compact furnace can be placed into a glove box.   It is an ideal furnace to explore the material for solid-state electrolyzing and new-generation superconductors


Furnace Construction

  • High-purity fibrous alumina insulation for maximum energy saving
  • Drop-down door for easy and safe sample loading as muffle furnace
  • Three 20 mm dia. holes are opened in front of the door used as a 3-tube furnace:
  • Three quartz tubes ( 20ODx16IDx200L mm) are included to insert inside the muffle furnace
  • Three sets of quartz blocks, KF16 adapters, needle valves, and  1/4" tube fitting are included 
  • Three thermal blocks are included to work as a standard muffle furnace. 

Quartz Tube & Flange

  • Three sets of One-end closed quartz tubes ( 20mm O.D. x 15.9mm I.D.x 200L )   ( Click  Pic. 1 to order more)
  • Three sets of  SS flange to achieve vacuum ( 10e-5 torr by turbo-pump)  ( Pic. 2)
  • Three sets of KF16 adaptors with needle valves and 1/4" tube fitting            (Pic. 3 )
  • Three quartz blocks ( 15 mm dia. ) shall be placed inside of the tube to block heat radiation
