The Carbolite Gero high-temperature tube furnace HTRH can be used horizontally at a maximum temperature of 1800°C.
High-quality insulation materials with low thermal conductivity enable low energy consumption and rapid heating. The insulation material and molybdenum disilicide (MoSi2) heater element are housed in a rectangular casing. The heater element is suspended vertically, making it easy to replace. At high temperatures and in the presence of oxygen, MoSi2 forms an oxide layer (SiO2) that protects the heater element from thermal and chemical corrosion. The 3-zone tube furnace (HTRH-3) achieves higher uniformity compared to single-zone products. These models are equipped with dedicated thermocouples and temperature controllers for each heating zone, making them particularly convenient for preheating gases necessary for reactions within the system. The HTRH does not come with a working tube built-in. The working tube can be selected as an additional accessory. The length of the working tube varies depending on the application and whether a modified atmosphere or vacuum is used.

Company information
Varda Scientific covers a wide range of products, from sample grinding, crushing, homogenization, and heat treatment for laboratory use, to particle size measurement, component analysis, cutting, polishing, embedding, and hardness testing. Varda Scientific has five brands: Leco, QATM, Carbolite Gero, Eltra, and MRB. Since 1999, we have been operating as Leco Corporation, handling products from Leco and Leco Technology. On January 1, 2014, we began handling Carbolite Gero, and at the same time, in line with the increase in the number of brands we handle, we changed our company name to Varda Scientific Corporation. In 2018, we started handling ATM and Qness, and in June 2019, MICROTRAC and Microtrac Bell joined the Varda Scientific Group. As of May 1, 2020, ATM and Qness merged to become QATM, further enhancing our capabilities and allowing us to better meet our customers' needs.
