Pipette headUsage:

1. Install the suction head

Press down firmly on the handle of the pipette and rotate it slightly as needed.

Incorrect operation: Strike the suction head forcefully. This method can cause damage to the suction head and even wear of the pipette handle, thereby affecting its sealing performance.

2. Range setting

Before operation, please select the correct pipette. The pipette can operate within the range of 10-100%, but operating at 10% requires high pipetting skills. Therefore, it is recommended to operate within the range of 35-100%.

Range adjustment: When adjusting from a small range to a large range, rotate continuously in the direction of the desired range, and then return to the desired range when the rotation exceeds 1/3 of the desired range. When adjusting from a large range to a small range, directly rotate continuously to the desired range.

3. Moisturizing and washing

Repeat the suction and drainage of the same sample two to three times, and rinse to provide the same contact surface for each subsequent suction, ensuring consistency in the operation.

Attention: Do not rinse with high or low temperature liquids!

4. Pipette TipsImmersion angle

When absorbing liquid, try to maintain a vertical position and the tilt angle should not exceed 20 °.

5. Depth of immersion of suction head

6. Immersion time of pipette tip

After suctioning, keep it in the liquid surface for one second before gently moving the pipette tip away, which is particularly important for large capacity pipettes or for suctioning viscous samples.

7. Liquid absorption speed

Uniform and continuous pipetting, control the pipetting speed well. If it is too fast, it may cause liquid spray, liquid or mist to rush into the interior of the pipette, contaminating components such as the piston.

8. Drainage and Blowing

First, press the piston to the first gear to discharge the fluid, pause briefly, and then press it to the second gear to blow the fluid.

There are four ways to drain:

9. Hand temperature

The pipette should not be held in the hand for a long time. When not in use, hang it on a stand or hang it in the hand to dry.
