Scientific research tube furnace RS 50/250/11

laboratoryfor general purposesvacuum

Product overview The RS series split-type tube furnaces are designed for horizontal operation and can be converted for vertical use with an optional frame. The split/opening design enables fast, safe replacement of working tubes and supports tubes of different materials and diameters. Models are available up to 1300 °C with heated lengths from 250 mm to 1000 mm. Gas supply and vacuum packages allow processing in protective gas, process gas or vacuum. Standard touch controller or PLC options enable automated process control and data logging.

Standard equipment
