1800C Compact Vacuum Tube Furnace (60mm OD) with Kanthal Heating Elements - GSL-1800X-KS60-UL


In stock
Item Number: GSL1800XS60

Personalization

GSL-1800X-KS60 is a compact tube furnace with Kanthal Super-1900C Grade MoSi2 Heating Elements, and high-quality alumina refractory board with ZrO2 liner. Vacuum sealing flanges with valves, vacuum gauge, and a high purity alumina processing tube (60mmO.Dx 610 mm L) are included for immediate use. The temperature of the GSL-1800X-KS60 tube furnace is controlled by a 30 segment programmable high precision SCR (Silicon Controlled Rectifier) digital controller with an accuracy of +/-1 ºC. This tube furnace has a max. working temperature up to 1800 ºC. It is widely used in material & chemical researching labs to sinter all types of new material samples under vacuum and other gas conditions. (Updated to UL Ready Version from 09/09/2015)

Tube Materials
High purity Al2O3 ceramic, Purity > 99.9%
Temperature controller
  • Eurotherm 3000 Series Programmable Temperature Controller.
  • 1 program, 24 segments programmed with ramping, cooling and dwelling steps
  • Temperature Accuracy:  ±  0.1ºC
Laptop & software (Optional)
  • Brand new laptop with Microsoft Windows 10 and Microsoft Office 2013 (30 days free trial) for immediate use.
  • Eurotherm iTools software enables the user to edit temperature profiles and manage heat-treatment recipes for MTI furnaces.
  • Note: Due to the complexity of the controller operation, we strongly suggest customers to purchase this PC control kit along with the furnace and our engineers will have the software & hardware pre-installed. Please note that this PC control kit is not for sale individually.
Processing Tube
  • Premier Grade alumina tube made in the USA
  • ID: 54mm x OD: 60 mm x 790 mm length
  • Four fibrous ceramic tube blocks are included for blocking heat radiation from inside tube (Ceramic blocks must be fully inserted into the furnace chamber before heating).
  • For 60mm tubes, it is recommended that customers purchase two pairs of tube support to prevent the tube from bending under high temperature (please click on the last picture to order).
                      
Sealing Flanges
  • One pair sealing flange with double silicone high-temperature O-ring is included.
  • Two SS needle valves and one dial vacuum gauge are installed with flange for immediate use.
  • Vacuum pressure can reach 50 mTorr by a quality mechanical vacuum pump and 10^-5 torr by turbo molecular pump. Please click the picture below to see flange assembling details.
