HTTF-1800 vacuum furnace is a bench top 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 are included for immediate use. The temperature of bench-top tube furnace is controlled by a 30 segment programmable high precision SCR (Silicon Controlled Rectifier) digital controller with an accuracy of +/-1 ºC. This horizontal tube furnace has a max. working temperature up to 1800 ºC. This vacuum tube furnace is widely used in material & chemical researching labs to sinter all types of new material samples under vacuum and other gas conditions.

See optional
Optional: MTS-02 PC control module (also including cable and software) is an add-on option for PC control. It is recommended to purchase the module together with the furnace. We install and test it before shipping. It is recommended to purchase the laptop (with software pre-installed) from us to avoid software conflict. Please note the module is not sold solely in the future. Eurotherm 3204 Temperature Controller is optional for an additional $1795 including installation and testing. This package also includes the communication cable (RS485 - USB) and software CD. |
Tube Materials: | High purity Al2O3 ceramic, Purity > 99.8% |
Processing Tube | Premier Grade alumina tube made in the USA ID: 54mm x OD: 60 mm x 1000 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). |
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 a turbo molecular pump. Please click the picture below to see the flange assembling details. |
Fitting Ports | Standard 1/4‘’ Barbed fittings with needle valves. For supplying high-pressure gas, you may replace the standard barbed hose fitting with the 304SS 1/4" Swagelok® Tube Fitting, please click underlined to order. Optional: In order to increase the throughput and achieve high vacuum, you may replace the standard barbed hose fitting with the KF25 adapter, please click the underlined to order. Optional: You may also consider using the parts in below to increase the vacuum efficiency Please click here to order digital vacuum gauge for precision vacuum control up to 10-4 torr You may click here to order flow-meter and install in tube flange KF25 Stainless steel Bellows KF25 Quick Clamps |
Vacuum Level | Limited by the vacuum pump 50 mtorr can be achieved by a mechanical pump 10^-5 torr can be reached by molecular pump The vacuum pump is not included, please order separately by clicking |
Power Cable & Plug | 10 feet long 10-3 AWG heavy duty UL approved power cable is included. Extra length cable can be ordered by click picture below-left The plug is not included. You can order from your local hardware store according to female plug in your lab, or order from the link below right (30A plug) |

Application Notes | In order to obtain accurate temperature inside the tube furnace, you need to perform a temperature calibration before use, please click here to learn how. How to set up ceramic tube and vacuum flange for Horizontal Tube Furnace Proper placement of tube blocks The tube furnaces with alumina tube are designed for use under vacuum and low pressure < 0.02 Mpa Never use graphite crucible in an alumina tube. The gas flow rate should be limited to < 200 SCCM (or 200ml/min) Vacuum limit definition for all alumina tube furnaces: * Vacuum pressures may only be safely used up to 1500°C |
