Yellow tips are also called tips, tips, etc. It is a kind of pipetting device that is commonly used in chemical and biological laboratories for small or trace amounts of liquids. It has the advantages of high accuracy, convenient measurement and simple operation. Different specifications are used to match pipette tips of different specifications.

To ensure better accuracy and precision, it is recommended that the pipetting volume be within the 35%-100% range of the tip. For most pipettes, especially multi-channel pipettes, it is not easy to install the tip: in order to pursue a good seal, after inserting the pipette handle into the tip, turn it left and right or shake it back and forth to tighten it.

Some people also use the pipette to repeatedly hit the tip to tighten, but this operation will cause the tip to deform and affect the accuracy, and in severe cases, the pipette will be damaged, so such an operation should be avoided.

For samples at room temperature, the yellow tip cleaning helps to improve the accuracy; but for high temperature or low temperature samples, the tip cleaning reduces the accuracy of the operation, please pay special attention to the user. The pipetting operation should maintain a smooth and appropriate suction speed; too fast suction speed may easily cause the sample to enter the sleeve, damage to the piston and sealing ring, and cross-contamination of the sample.

Notice:

1. Maintain correct posture when pipetting; do not hold the pipette tightly at all times, use a pipette with finger hooks to help relieve hand fatigue; change hands frequently if possible.

2. Regularly check the sealing condition of the yellow tip. Once the sealing is aged or leaking, the sealing ring must be replaced in time.

3. Correct the pipette 1-2 times a year (depending on the frequency of use).

4. For most pipettes, before use and after using for a period of time, apply a layer of lubricating oil to the piston to maintain tightness; for pipettes with conventional ranges, no lubricating oil also has ideal tightness. .
