The tank cleaning instrument adopts a high-power vacuum pump and a multi-channel parallel design, which greatly improves the cleaning speed. The digital control system allows real-time monitoring of key indicators such as system pressure and vacuum degree, and automatically adjusts relevant parameters to ensure consistency in cleaning quality between different batches. The use of oil-free vacuum pumps avoids the potential impact of oil contamination on the samples; The wide range temperature control meets diverse experimental requirements, enhancing the applicability and stability of the equipment. Suitable processing capacity can be selected according to the specific needs of the laboratory, such as supporting simultaneous cleaning of 4, 6, 8, or even 12 tanks, to adapt to different workload changes.

The measurement steps of the tank cleaning instrument:

1. Preliminary preparation

-Read the instruction manual: Operators need to carefully read the device's user manual, familiarize themselves with its structure, functions, and operating procedures.

-Wear protective equipment, including gloves, goggles, masks, etc., to ensure personal safety.

2. Sampling efficiency test

-Set different conditions: Conduct multiple sampling tests under different flow rates and liquid conditions.

-Data comparison analysis: Compare the actual measured data with theoretical values to evaluate the sampling accuracy of the equipment.

3. Cleaning effect test

-Place pollutants: Place pollutants of different types and concentrations in containers to be cleaned.

-Execute cleaning procedure: Use a fully automatic sampling and cleaning device to clean the container.

-Detecting residual content: Using professional methods to detect the residual content in the cleaned container, in order to evaluate the effectiveness of the equipment in removing pollutants.

4. Stability testing

-Continuous sampling operation: Continuously performing sampling operations within a certain time range.

-Record and compare data: Record relevant data after each sampling and compare the consistency of these data to determine the stability of the equipment.

5. System cleaning and validation

-Circulating filling of ultra pure gas: using ultra pure nitrogen or zero air for circulating filling.

-Vacuum treatment: further ensure the cleanliness of the sampling system by vacuuming.
