AZ is an excellent 8-zone tube furnace for controlling temperature profiles.
The 8 zones, with thick insulation and high-symmetry heating elements built into the entire furnace, achieve temperature uniformity within ± 5°C. The advantage of individually controlling the 8 zones is that it is important for extending the thermal length within the furnace. Additionally, the temperature profile can be precisely and freely controlled by the user, either rising linearly or peaking. The optimal application for AZ is, for example, chemical vapor deposition. It can create a temperature gradient where precursor materials are evaporated in the high-temperature end zone and vapor is condensed onto the substrate in the low-temperature end zone. All zones are controlled and monitored by individual thermocouples.

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.
