Text Box: Schematical parts list for various methods Text Box: Notes 1 Silica enclosing and gas tubes are long-term stable to 900 °C, and can be used up to around 1100 °C for short term. Each cooling below 400 °C of silica parts reduces lifetime. 2 Support tube assemblies for disk sample are produced with outer diameter 10, 12, 16, 20 or 24 mm. 3 For support tubes with outer diameter 16, 20, and 24 mm a multibore inner gas tube is possible and recommended. For 10 and 12 mm supports only a simple 3 or 4 mm gas tube may be used. 4 Straight alumina or bent silica. 5 K- or S-type thermocouples. 6 For support tubes with outer diameter 16, 20, and 24 mm IN2N# is recommended, for 12 mm or less - IN2. 7 All parts can be also manufactured by users after instructions in the manual.
