Locking ring

Locking ring (c) is a dedicated spare part for single-channel pipettes that disables the spring action during use. It is intended for instruments covering the volume range from 2,5 µL to 1,000 µL and restores controlled, non-springing piston behaviour when this function is required. The component supports stable liquid handling in routine laboratory work and helps maintain consistent operator feel on compatible single-channel models. Supplied as one piece with a net weight of 0,009 kg and a gross weight of 0,010 kg, the locking ring belongs to the accessories and replacement-parts programme from manufacturer Eppendorf. Its compact packaging volume of 0,001 m³ simplifies storage and inventory management in busy labs. Typical application areas include molecular biology, clinical diagnostics, quality-control and general liquid-handling workflows where temporary cancellation of spring return improves precision or comfort. Manufactured in Germany, the part integrates directly with the corresponding pipette assemblies without altering factory calibration settings. This locking ring therefore provides a straightforward mechanical solution for laboratories that need to restore or adapt the spring behaviour of their single-channel pipettes.
