Sealed reaction tube for tube electric furnace operations. Samples placed at the sealed end undergo calcination under protective gas atmosphere, completely isolated from ambient air and impurities.
Sealed liquid reservoir bubbling container where inert gas passes through reagent liquid to generate bubbles—used for reagent humidification, raw material deoxidation and gas-liquid reaction processes.
High-purity precursor raw material sealed storage vessel. After high-temperature vaporization, carrier gas transports precursor vapor for CVD thin-film coating gas source supply with zero contamination.
Leak-proof container for HF acid and concentrated corrosive liquid reactions. Hermetically sealed to prevent leakage with no impurity precipitation that could contaminate test samples.
Compared to borosilicate glass tubes, this quartz end-capped tube offers full HF acid resistance, sustained 1100°C operation, integrally fused end cap with superior sealing performance, excellent thermal shock resistance to prevent cracking, and high purity construction suitable for high-purity sealed material processing—making it the definitive choice for demanding semiconductor, chemical and laboratory applications.
