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 Post-Digestion: After digestion, allow to cool naturally to room temperature. Release pressure before opening the lid, and do not operate while hot.
- 4 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.
Frequently Asked Questions (FAQ)
Q1: What is the main application of the PTFE COD Digestion Tank?
A1: It is specifically designed to safely digest water samples (such as industrial wastewater, domestic sewage, and surface water) under high temperature and high pressure conditions for Chemical Oxygen Demand (COD) determination.
Q2: What is the maximum operating temperature for this digestion tank?
A2: The digestion tank has a temperature resistance of ≤200°C. It is important to strictly monitor the temperature and heating rate to stay within safe operating parameters.
Q3: How much sample reagent can I put into the digestion tank?
A3: The reagent should never exceed 2/3 of the container's total volume. For samples containing high levels of chlorine or organic compounds, pretreatment is required.
Q4: What capacities and specifications are available?
A4: We offer multiple standard sizes ranging from 30ml up to 200ml (specifically 30ml, 50ml, 60ml, 100ml, and 200ml) to meet different laboratory testing requirements.
Q5: How should the tank be opened safely after digestion?
A5: Once digestion is complete, you must let the tank cool naturally to room temperature. Always release any residual pressure completely before unscrewing the lid, and never attempt to open it while it is hot.
Q6: What safety features does this PTFE vessel offer?
A6: It is designed with reserved explosion-proof holes for enhanced safety, features a robust threaded lid for a tight, high-pressure seal, and has a thickened inner wall to extend its service life.
