Operation Steps for the Pipetting Workstation

The pipetting workstation is a core piece of equipment in modern research laboratories, playing a crucial role in ensuring experimental quality and enhancing research efficiency. Below are the basic operation steps for the pipetting workstation:

Preparation underway

Prior to operating the pipetting workstation, a series of preparatory steps must be taken to ensure the smooth progress of the experiment. Firstly, the workstation should be placed steadily on the lab table and the power supply connected. Once the instrument has completed initialization, select an appropriate pipette tip according to the specific requirements of the experiment and install it onto the aspiration device. It is crucial to ensure a tight and leak-free connection between the pipette tip and the aspiration device to guarantee the accuracy of pipetting.

2. Set Pipetting Parameters

After preparations are completed, set the pipetting parameters through the instrument interface. These parameters include, but are not limited to, the volume of aspiration, the volume of dispensation, the pipetting speed, and the number of pipetting cycles. Once set, reconfirm that all parameters are correct to ensure the smooth progress of the experiment.

3. Absorption and Emission

During pipetting, operators should gently insert the pipette tip into the liquid to be aspirated, avoiding the formation of bubbles or liquid splashes. After pressing the aspiration button, wait for the liquid to be completely drawn into the pipette tip before releasing the button. When dispensing, position the pipette tip above the target container, press the dispensing button, and ensure the liquid is dispensed accurately.

4. Routine Maintenance

After completing the pipetting tasks, it is crucial to promptly clean the pipette tips. Additionally, regular maintenance of the pipetting station is necessary, which includes checking the connections of all instrument components, cleaning the interior of the instrument, and replacing worn-out parts. In terms of maintenance, attention should also be given to the following points: first, keep the pipetting station clean and dry to prevent dust or moisture from damaging the instrument; second, regularly inspect the integrity of the power and data cables to ensure normal power supply and communication for the instrument; third, calibrate the pipetting station regularly to ensure long-term high precision and stability.

These are the basic operating steps for the pipetting workstations. It's important to note that different pipetting workstations may have some operational variations. Therefore, when in use, always strictly follow the equipment's operation manual.
