Definition and characteristics of infrared quartz digestion furnace
2025-04-30
An infrared quartz digestion furnace is a heating device used for laboratory sample pretreatment. It combines infrared heating technology with the properties of quartz materials and is mainly used for high-temperature digestion, dissolution, and boiling of organic or inorganic samples. The core definition and characteristics are as follows:
Definition
The infrared quartz digestion furnace achieves rapid and controllable heating of samples through a combination of infrared radiation heating (efficient and uniform heat transfer) and quartz containers/heating elements (high-temperature resistance, corrosion resistance). It is often used in scenarios requiring strong acid (such as nitric acid, sulfuric acid) digestion of samples, such as in environmental monitoring, food testing, and biochemical analysis.
Core Features
Infrared Heating Technology
Direct radiation heating, fast heating, high energy utilization.
Avoids contact heat loss of traditional electric hot plates or metal heating.
Quartz Material Components
Quartz digestion tube: High temperature resistance (up to 1200℃ or more), acid and alkali corrosion resistance, suitable for strong acid environments.
Quartz heating tube/infrared emitter: Good thermal stability, long lifespan.
Precise Temperature Control
Usually equipped with a PID temperature control system, the digestion temperature can be adjusted (e.g., 100~400℃ range).
