1. Daily cleaning

Appearance cleaning

After each use, wipe the outer shell of the pipette with a clean soft cloth to remove dust, stains, and liquid residue from the surface.

If the pipette comes into contact with corrosive liquids or biological samples, it should be immediately wiped with an appropriate disinfectant or cleaner, but the cleaner should be avoided from entering the interior of the pipette.

Cleaning of the suction head installation part

Regularly check if there are any residual liquids or impurities in the installation part of the suction head. If there are, use a cotton swab or soft bristled brush dipped in a small amount of alcohol to gently wipe it off.

Avoid scratching with hard objects to prevent damage to the sealing of the suction head installation part.

2. Regular calibration

periodic calibration

The accuracy of multi-channel pipettes will gradually decrease due to factors such as frequency of use and environmental changes, so regular calibration is required.

It is generally recommended to calibrate every 3-6 months, and the specific frequency can be adjusted according to the usage frequency and laboratory requirements.

calibration method

Professional calibration equipment can be used for calibration, or it can be sent to a professional calibration institution for calibration.

After calibration, the calibration results should be recorded to track the performance changes of the pipette.

3. Prevent liquid backflow

Operating Specifications

During the pipetting process, avoid tilting the pipette excessively to prevent liquid from flowing into the interior of the pipette.

If liquid accidentally enters the interior of the pipette, it should be immediately stopped from use, and the relevant components should be disassembled for cleaning and drying.

regular inspection

Regularly check the interior of the pipette for any liquid residue, especially in the piston and sealing ring parts.

If liquid residue is found, it should be cleaned in a timely manner to avoid liquid corrosion of internal components.

4. Proper storage

Storage environment

Store the pipette in a dry, clean, and warm environment, avoiding direct sunlight and humid conditions.

When storing, the pipette should be placed vertically and avoid being placed flat to prevent liquid residue.

Dust protection

Dust covers or specialized pipette storage boxes can be used to prevent dust and impurities from entering the interior of the pipette.

5. Regular maintenance

Check the sealing performance

Regularly check the sealing of the suction head installation part and piston to ensure that there is no air or liquid leakage.

If a decrease in sealing is found, the sealing ring should be replaced in a timely manner.

Lubricating components

According to the instructions for using the pipette, regularly lubricate the parts that require lubrication, but be careful to use specialized lubricants and avoid using regular lubricants.

Check the spring and button

Regularly check the elasticity of the spring and the flexibility of the button. If the spring is found to be aging or the button is stuck, it should be replaced or repaired in a timely manner.

6. Avoid excessive use

Reasonably arrange the frequency of use

Avoiding prolonged continuous use of pipettes and taking appropriate breaks can reduce wear and tear on mechanical components.

If the frequency of use is too high, it is recommended to prepare a backup pipette and use it alternately.

Avoid overloaded use

Do not exceed the maximum range of the pipette for pipetting to avoid damaging the piston and spring.

7. Professional maintenance

Timely repair

If the pipette malfunctions or its performance decreases, it should be promptly repaired by professional maintenance personnel to avoid self disassembly and repair.

Regular inspection and maintenance

Conduct a comprehensive inspection and maintenance once a year, including checking, cleaning, and replacing worn parts of internal components.

Through the above maintenance measures, the service life of the multi-channel pipette can be effectively extended, while ensuring its stable performance and meeting the needs of laboratory use.
