1、 Core elements of selection
Number of test holes and detection efficiency
Single well instrument: suitable for low flux detection scenarios, such as small laboratories or single sample analysis.
Porous instrument (3-well/6-well): supports batch testing, significantly improving laboratory efficiency.
Stability of temperature control system
Key indicators: The temperature of the evaporation bath should be stable at 160-165 ℃ (in accordance with GB/T 8019 standard), and the fluctuation range should be less than ± 1 ℃.
Technical advantages: Metal bath constant temperature technology heats up quickly and evenly, avoiding data deviation caused by local overheating.
Accuracy of air velocity control
Standard requirement: The air flow rate in each hole must be stable at 600mL/s to ensure consistency in testing conditions.
Monitoring method: The floating ball flowmeter can intuitively display the airflow status, improving the reliability of testing.
Safety and Compliance
Safety features: triple protection against overheating, dry burning, overpressure, and water shortage to avoid operational risks.
Standard compliance: It must comply with domestic and foreign standards such as GB/T 8019, GB/T 509, ASTM D381, etc., to ensure the legal validity of the data.
Additional Features and Scalability
Data management: Digital display of temperature and pressure, some models support RS232 communication interface for easy data recording and analysis.
