Description
Locking ring for single-channel pipettes is a specialised laboratory accessory that disables the spring action of the tip cone on selected instruments. It is intended for Eppendorf Research® 3, Xplorer®, Research® plus and Reference® 2 single-channel pipettes, allowing the tip-cone suspension to be locked out when a fixed position is required during liquid-handling workflows. The set contains five locking rings and is offered by manufacturer Eppendorf as a practical solution for pipette customisation in research, quality-control and routine laboratory environments. By simply fitting the ring, users can temporarily override the spring-loaded tip cone without tools or permanent modification of the pipette. This supports applications that benefit from a rigid tip interface, such as certain repetitive dispensing steps or specialised sample-preparation protocols. Compact and lightweight, the accessory integrates directly with the lower part of the compatible single-channel models and helps laboratories maintain flexible yet controlled pipetting setups across molecular biology, analytical and general life-science work.
This article is part of Pipetting accessories, in Pipettes & pipette tips.

Questions about Locking ring for singl.chan.pipettes 5pc
What is this article?
Locking ring for singl.chan.pipettes 5pc is the article on this page. Luminix Health distributes Eppendorf for laboratory use. It sits in Pipetting accessories, inside Pipettes & pipette tips, in Lab consumables.
Pipetting accessories are the boxes, the ejectors, the spare seals and the carousel parts around a pipette and its tips. A seal set is model-specific. A tip box that does not match the rack footprint will not sit on the pipette aid.
A pipette moves a measured volume. A volumetric pipette delivers one line. A graduated pipette delivers along a scale. A Pasteur pipette is an uncalibrated transfer. A piston pipette uses a tip, and the tip has to seal on that pipette. A filter tip adds a barrier so aerosol from the sample does not reach the piston. Serological pipettes are the long graduated tubes used with a controller. The volume and the fit are the specification. Piston pipettes are treated under ISO laboratory apparatus. In-vitro work also meets ISO in vitro diagnostic systems.
