kanalpipetter

Kanalpipetter, also known as channel pipettes or multichannel pipettes, are laboratory instruments used to aspirate and dispense liquids. They are a variation of single-channel pipettes but are equipped with multiple tips, typically in a row of 8 or 12. This design allows for the simultaneous handling of multiple samples, significantly increasing efficiency in tasks that involve processing numerous specimens.

The primary advantage of using kanalpipetter lies in their ability to process multiple samples in parallel, which is crucial for high-throughput applications such as ELISA assays, PCR setup, and cell-based screening. By reducing the time spent on individual pipetting steps, researchers can accelerate experimental workflows and reduce the potential for errors associated with repetitive manual operations.

Kanalpipetter operate on the same volumetric principles as single-channel pipettes, utilizing either air displacement or positive displacement mechanisms. The volume dispensed by each channel is precisely controlled by an adjustable volume setting. The tips are usually disposable plastic consumables that are attached to the pipette before use and discarded afterward to prevent cross-contamination.

When using a kanalpipetter, it is essential to ensure that all tips are properly seated and that the instrument is held vertically to maintain accuracy. Consistent immersion depth and aspiration/dispensing speeds are also critical for reproducible results. Maintenance typically involves cleaning the pipette and ensuring smooth operation of the volume adjustment mechanism. The multichannel design makes them indispensable tools in molecular biology, biochemistry, and other life science disciplines where large numbers of samples are routinely handled.
