Electronic
pipettes differ from manual pipettes primarily in how they dispense and measure liquid volumes. Here's how they typically differ in operation:
Dispensing Mechanism: Electronic pipettes use a motorized system to aspirate and dispense liquid, while manual pipettes rely on manual manipulation of a plunger or button.
Volume Selection: Electronic pipettes usually have a digital interface where users can input the desired volume directly, whereas manual pipettes have a physical dial or plunger that must be adjusted to set the volume.
Precision and Accuracy: Electronic pipettes often offer greater precision and accuracy in volume delivery due to their automated mechanisms and digital controls. They can dispense precise volumes consistently, which is especially beneficial for tasks requiring high accuracy.
Programming and Memory: Some electronic pipettes offer programmable features, allowing users to save frequently used settings or create custom pipetting protocols. This can streamline repetitive tasks and ensure consistency across experiments.
Ergonomics: Electronic pipettes may feature ergonomic designs with comfortable grips and reduced hand strain, as the motorized operation reduces the physical effort required compared to manual pipettes.
Dispensing Modes: Electronic
pipettes may offer various dispensing modes, such as repetitive dispensing, mixing, and reverse pipetting, which can be useful for specific applications like serial dilutions or sample mixing.
User Interface: Electronic pipettes typically have a display screen where users can view settings, volume readings, and other relevant information, providing real-time feedback during pipetting procedures.
Battery or Power Source: Electronic pipettes require power to operate, usually from rechargeable batteries or direct connection to a power source, whereas manual pipettes do not require external power.
