MUFU-T17 1700 °C muffle furnace — MoSi₂ heating rods, 30-segment program controller, 2 to 36 L

The MUFU-T17 1700 °C muffle furnace series is a range of high-temperature laboratory furnaces with a vacuum-formed polycrystalline mullite fibre chamber, molybdenum disilicide (MoSi₂) heating rods and a microprocessor PID program controller with a B-type thermocouple. The furnace reaches a maximum of 1700 °C and holds the set temperature within ±1 °C. A 30-segment program runs heating, holding and cooling as one stored profile, and the heating switches off as soon as the door opens. Six chamber sizes — 2, 4, 8, 12, 20 and 36 L — cover sintering, melting and the analysis of metals, non-metals and compound materials.

One furnace series for sintering, melting and materials analysis up to 1700 °C

Work above 1600 °C needs heating elements and a chamber made for it: sintering of technical ceramics and powders, melting of glass and frits and the analysis of metals and compound materials ask for a temperature that is held for hours. The MUFU-T17 1700 °C muffle furnace is built for that work, with high-purity molybdenum disilicide (MoSi₂) heating rods and a B-type thermocouple. The vacuum-formed polycrystalline mullite fibre chamber has a low thermal mass, and the double shell with an air gap and two air-guiding channels keeps the housing cooler.

Key characteristics

• Maximum temperature 1700 °C, the highest among the MUFU muffle furnaces.
• Control accuracy ±1 °C, display resolution 1 °C.
• Polycrystalline mullite fibre chamber — vacuum-formed, low thermal mass.
• 30-segment program controller — microprocessor PID, fixed-value or program operation.
• MoSi₂ heating rods and a B-type thermocouple.
• Safety — heating cut-off on door opening, over-temperature alarm and leakage protection.

Suitable for

• Ceramics and materials laboratories — sintering of technical ceramics, powders and powder-metallurgy samples that need more than 1600 °C.
• Glass and enamel laboratories — melting of glass, frits and enamels in suitable crucibles.
• Research and quality laboratories — analysis of metals, non-metals and compound materials.
• Metal workshops and material laboratories — high-temperature treatment of small parts and test pieces.
• Universities and institutes — materials science teaching and research.

Why a 1700 °C muffle furnace with MoSi₂ heating rods and a program controller

Molybdenum disilicide heating rods are the usual choice for laboratory furnaces above 1400 °C. In the MUFU-T17 1700 °C muffle furnace they work together with a B-type thermocouple and a microprocessor PID controller that holds the set temperature within ±1 °C. The 30-segment program stores ramps and dwells, so heating, holding and cooling follow the same profile in every run, independent of the operator.

Chamber mouth, exhaust chimney and door safety switch

The chamber mouth of the MUFU-T17 1700 °C muffle furnace is made of mirror-finish stainless steel that does not discolour in long-term use, and an exhaust chimney is fitted as standard. The hinged door has a lockable handle, and a door switch cuts off the heating as soon as the door opens, which protects the operator and the heating elements. Heat-insulating gloves and crucible tongs are supplied with the furnace.

Models and product codes

The MUFU-T17 1700 °C muffle furnace series has six chamber sizes. The 2, 4 and 8 L models run on 220 V single-phase; the 12, 20 and 36 L models need a 380 V three-phase connection. A 30-segment LED program controller is standard; the 7-inch touch-screen controller MUFU-TS7 (PRO8073), which shows the temperature curve, is fitted in the factory on request. Choose the size by the number and size of crucibles per run, and quote and order with the COLO product code.

MUFU-T17-12, MUFU-T17-20 and MUFU-T17-36 need a three-phase 380 V connection; MUFU-T17-8 draws 9 kW on a single-phase supply. The supply circuit is confirmed with COLO.Science before installation.

Installation, qualification and calibration

A MUFU-T17 1700 °C muffle furnace needs a stable, non-combustible base, free space around the housing and for the exhaust chimney, and ventilation — under an extraction or in a ventilated room when samples release fumes. The 12, 20 and 36 L models need a three-phase 380 V connection, and the supply circuit is confirmed before installation.

For regulated laboratories COLO.Science installs the furnace and carries out installation and operational qualification (IQ/OQ) with protocols. The chamber temperature can be checked and calibrated against a reference thermometer placed in the chamber.
