Base and Inner Tube for D-Torch. Compatible with Glass Expansion D-Torch for PerkinElmer Elan 6000, 9000, DRC II, DRC-E and NexION 300/350.A patented, precision-engineered, demountable torch, incorporating a ceramic inner tube for greater robustness. D-Torch also features an interchangeable injector, allowing installation of a specific injector, whether it be for aqueous (~2.0mm ID), organics (<2.0mm ID), high TDS (>2.0mm ID) or HF (alumina). Compatible with all EMT injectors.The D-Torch is the only design with an optional ceramic outer tube (501907158, 31-808-2849). The quartz outer tube for the PerkinElmer Elan 6000, 9000, DRC II, DRC-E and NexION 300/350 (501907157, 31-808-2848) is ideal for most applications while the ceramic outer tube is best for high TDS, organics, or HF matrices. Glass Expansion is ISO 9001:2015 certified by AB Certification, No. AU4501-9001
