## Answers.
1. When choosing a pipette for cell culture, several factors should be considered. Firstly, the volume range needed for your experiments, as different pipettes have different volume capacities. Additionally, the accuracy and precision of the pipette are crucial for obtaining reliable results in cell culture work. The ergonomics of the pipette, such as the weight and design, should also be taken into account to ensure comfortable and efficient pipetting. .
2. There are two main types of pipettes commonly used in cell culture: air displacement and positive displacement pipettes. Air displacement pipettes are ideal for general liquid handling tasks and are suitable for aqueous solutions. On the other hand, positive displacement pipettes are recommended for viscous or volatile liquids, as they utilize a disposable piston that comes into direct contact with the liquid being pipetted, reducing the risk of contamination.
3. Pipette calibration is essential in cell culture experiments as it ensures the accuracy of volume measurements. Inaccurate pipetting can lead to inconsistent results and affect the reproducibility of experiments. Regular calibration of pipettes is recommended to maintain their accuracy over time. Calibration certificates provided by manufacturers should be kept for reference and pipettes should be recalibrated if any deviations in performance are noticed.
