O-rings in Eppendorf multichannel pipettes are elastomer sealing components located within the lower piston assembly. These rings create an airtight seal between the piston and the cylinder, which is essential for maintaining accurate air displacement during aspiration and dispensing.
The O-rings ensure consistent vacuum generation across all channels, allowing the pipette to aspirate and dispense liquid volumes with high precision and repeatability. Proper sealing prevents air leakage that could lead to volume errors or inconsistent pipetting performance.
