In the field of laboratory precision instrument cleaning,LW8518The test tube bottle washing machine, with its intelligent control system and modular design, has become a key equipment for improving experimental efficiency.This article analyzes its core usage methods from three aspects: operational procedures, safety standards, and maintenance points.

　　1、 Standardized operating procedures

　　1. Power on self-test

After connecting the power, the device automatically starts the self-test program, and the 7-inch LCD touch screen displays the system status. Check if the double-layer detachable insulation shell is sealed and confirm that there is sufficient remaining capacity in the built-in 2 × 5 liter cleaning agent container. Adjust the brightness of the display screen to the appropriate observation value through the PID control system.

　　2. Basket rack loading

Adopting a modular basket frame design, it can handle:

① 2ml liquid phase small bottles ≥ 392;

② Less than 50ml burette/test tube ≥ 380 tubes;

③ ≥ 64 beakers below 250ml.

When loading, follow the principle of 'light on top and heavy on bottom', ensuring that the test tube mouth faces downwards and maintains a distance of 1-3cm from the rotating spray arm to avoid nozzle blockage.

　　3. Program settings

Select one of the 20 standard programs or customize parameters through the microcomputer control system:

① Temperature control: The dual temperature monitoring system achieves an accuracy of ± 1 ℃;

② Circulating flow rate: Swedish imported pump automatically adjusts 0-400L/min;

③ Cleaning agent distribution: Precisely add 0.1-5ml/time using a peristaltic pump.

　　4. Operation monitoring

After activation, the electronic door lock automatically locks, and the pull-down perspective window is equipped with LED lighting, allowing real-time observation of the 360 ° coverage cleaning effect of the upper, middle, and lower rotating spray arms. The system uploads operational data to the cloud through the GPS positioning module, and automatically triggers sound and light alarms and prints fault codes in case of abnormalities.

　　2、 Safety protection regulations

Set operator/administrator/system engineer permissions to prevent unauthorized modification of parameters. For example, administrators can limit the cleaning temperature to a maximum of 90 ℃ to prevent glassware from breaking.

　　2. Multiple protection mechanisms

① Overheating protection: The circulating pump will automatically shut down when the temperature exceeds 65 ℃

② Anti dry burn protection: Interrupt program when inlet flow rate is below 0.5L/min

③ Electrical safety: Grounding resistance ≤ 0.1 Ω, equipped with leakage protection device

　　3、 Key points of maintenance and upkeep

　　1. Daily cleaning:Clean the pipeline with a matching neutralizing agent every week, dismantle the four stage filtration system (precision 0.2 μ m) and replace the filter element every month, and remove scale with acidic additives every quarter.

　　2. Consumables management:The built-in cleaning agent container needs to be replenished every 3 months, and alkaline reagents and acidic reagents should be stored separately. The peristaltic pump silicone tube is replaced every 500 cycles to ensure measurement accuracy.

The LW8518 test tube bottle washing machine reduces the traditional manual cleaning time from 2 hours per batch to 30 minutes through intelligent control and modular design, and reduces the risk of cross contamination by 92%. Its data traceability function, which complies with the ISO 8655 standard, provides critical support for laboratory certification and promotes the upgrading of scientific research processes towards standardization and automation.
