This range of laboratory scale vacuum furnaces is designed to provide high specification products economically. The VTTF series of horizontal tube furnaces is based on a standard design and is offered at 1200°C and 1500°C.
Standard features: - Vacuum vessel - ceramic tube fitted with stainless steel end seals; - Rotary pump: two stage sliding vane type; - Water cooled oil diffusion pump; - Manually operated backing/roughing and baffle valve ; - Pirani gauge - low vacuum monitoring; - Penning gauge - high vacuum monitoring; - Ultimate vacuum - better than 1 x 10-5mbar, with clean empty work tube. Options - Gas inlet with additional safety system for use with combustible atmospheres; - Flowmeters and valves for control of gas throughput; - Three zone control; - Semi-automatic or fully automatic vacuum/heating cycles; - Vertical operation; - Water cooled diffusion pump. |  |
