1. Product Overview
The mixed box and tube furnace is a multi-functional high-temperature heat treatment equipment that integrates the advantages of a box furnace and a tube furnace. It supports dual working modes with quick switching. When the furnace tube is removed, it works as a standard box furnace for atmospheric sintering, calcination, annealing and ashing. When equipped with a quartz/alumina tube and vacuum sealing flanges, it converts into a professional tube furnace for vacuum and controlled-atmosphere heat treatment.
Equipped with an intelligent PID temperature control system, precise gas flow system and standard vacuum interface, this all-in-one furnace saves laboratory space and procurement cost. It is widely used in universities, research institutes and new material enterprises for material research, sample preparation and small-batch production.
