Usage Recommendations

1. Using pipettes

1.1 The use of pipettes should follow these guidelines:

1. Set the pipette volume within the specified range and use compatible tips.
2. To ensure accuracy, use high-quality, uncontaminated tips.
3. Keep the immersion depth of the tip consistent or similar each time you aspirate.
4. Maintain the pipette vertically or at an angle of no more than 20 degrees from vertical.
5. Pre-wetting (1-3 times) the tip can improve pipetting accuracy.
6. Never invert or lay the pipette flat when there is liquid in the tip. Always keep the instrument vertical and store it as vertically as possible.
7. Liquid must not enter the areas that contact the piston or seal, as well as the electronic components including the display, trigger button, and eject button.
8. Do not use corrosive solvents to clean the pipette. When cleaning, it is best to use a damp cloth (with diluted mild detergent) that is not cotton.
9. Ensure that the display, trigger button, and eject button are dry.

Warning

The smart pipette is an advanced laboratory product that requires careful maintenance; please operate according to the guidelines.

1.2 Tip Immersion Depth

The immersion depth of the tip is critical. If it exceeds the recommended depth, the measured volume may be inaccurate and exceed standards. The angle of the tip is also important.

The recommended insertion depths for each model of sample are as follows:

Volume Range	Immersion Depth
0.1-1 µL	1mm
1-100 µL	2-3mm
100-1000 µL	2-4mm

1.3 Grip

@Pette Mini does not restrict your grip position; you can choose any grip style you prefer for holding the pipette.

2. Possible Causes of Malfunction and Solutions

Issue	Possible Cause	Suggested Solution
Tip ejector does not reset after ejection	System failure or spring malfunction	Contact customer service for inspection; the tip ejector reset spring may need to be replaced if necessary.
Screen touch failure	System failure. Dropping or impact may cause the connector to come loose or the screen module to be damaged.	Please contact customer service for inspection; the screen module may need to be replaced if necessary.
Button failure	System failure. Forcefully pressing the aspirate/dispense button may cause the button to malfunction.	Contact customer service for inspection; the button or securing components may need to be replaced if necessary.
