Product Features
- 1 Samples: The reagent should not exceed 2/3 of the container's volume. Samples with high chlorine or high organic content require pretreatment.
- 2 Temperature resistance: ≤200° C. Strictly control the temperature and the heating rate according to regulations, and do not exceed the temperature limit.
- 3 Cooling & Pressure: After digestion, allow to cool naturally to room temperature. Release pressure before opening the lid, and do not operate while hot.
- 4 System Compatibility: Only for use in compatible systems. Avoid direct contact of highly corrosive reagents with the container wall, and do not scrape with hard tools.
- 5 Maintenance: Inspect the container and seals before and after use. After cleaning, dry and store with the seal intact.
