Tips For Using Electric Pipettes

Electric pipettes are designed with simplicity and flexibility in mind, adding a variety of unique features to traditional pipettes. There are many models of electric pipettes to choose from. Electric pipettes combine rigorous and precise mechanical technology with ever-changing electronic technology.

The electric pipette is connected to the computer, which can easily write programs for the pipette, modify the pipetting mode at any time, and strengthen the laboratory GLP specifications and maintenance functions.

The common sense of using electric pipettes:

1.Use a suitable tip: To ensure better accuracy and precision, it is recommended that the pipetting volume is within the range of 35% -100% of the tip.

2.Tip installation: For most brands of pipettes, especially multi-channel pipettes, it is not easy to install the tips: in order to achieve good sealing, you need to insert the pipette handle into the tip, left, and right Turn or rock back and forth to tighten tightly.

Some people also use electric pipettes to repeatedly hit the tips to tighten, but this operation will cause the deformation of the tips and affect the accuracy, and severely damage the pipettes, so such operations should be avoided.

3. Tip immersion angle and depth: Control the tip immersion angle within 20 degrees, and it is better to keep it vertical; the tip immersion depth is recommended as follows: Pipette specifications Tip immersion depth 2 μL and 10 μL 1 mm 20 μL and 100 μL 2-3 mm 200 μL and 1000 μL 3-6 mm 5000 μL and 10 mL 6-10 mm Washing will reduce the accuracy of the operation, please pay special attention to users.

4. Aspiration speed: The pipetting operation should be smooth and appropriate; the excessively fast aspiration speed may easily cause the sample to enter the sleeve, causing damage to the piston and seal ring, and cross-contamination of the sample.

Proper placement of electric pipettes:

After use, you can hang it upright on the pipette holder, but be careful not to drop it. When there is liquid in the pipette tip, do not place the pipette horizontally or upside down, otherwise, the liquid backflow will corrode the use of the piston spring pipette.
