Description
Ref.2 fixed tip ejector sleeve 250 µL blue is a replacement accessory for laboratory pipettes belonging to the Reference® 2 product family. This fixed ejector sleeve is colour-coded blue to match the 250 µL volume designation and provides secure tip ejection on compatible instruments. Offered as a single piece weighing 0,006 kg net and occupying a packaging volume of 0,001 m³, the part is practical for spare-parts inventories and service kits. It is intended for maintenance of fixed-volume Reference® 2 pipettes used across research, clinical-support and quality-control workflows where consistent tip handling is required. The distinctive blue colour coding facilitates immediate visual identification, helping laboratory staff avoid mix-ups between different volume sleeves. Produced by manufacturer Eppendorf as a genuine accessory under the registered Reference ® trademark and classified as product type Reference 2, the sleeve restores the original tip-ejector function without modification of the pipette design. Regular replacement of worn ejector sleeves contributes to sustained pipette performance and reliable liquid-handling results in daily laboratory practice.

Questions about Ref.2 Ejector sleeve fixed 250µL blue
What is this article?
Ref.2 Ejector sleeve fixed 250µL blue is the article on this page. Luminix Health distributes Eppendorf for laboratory use. It sits in Pipette stands, calibration & accessories, inside Liquid handling, in Instruments de précision.
A pipette stand holds piston pipettes upright so liquid does not run into the piston. Calibration accessories and certificates are how a pipette's delivered volume is shown to be inside tolerance. A stand is also a carousel. The certificate belongs to one pipette, identified by serial number.
A piston pipette delivers a set volume of liquid by air displacement or, for viscous and volatile liquids, by positive displacement. A single channel is the ordinary tool. A multichannel repeats the same volume across a row of a plate. A bottle-top dispenser meters reagent from the bottle it sits on. The accuracy is a property of the pipette and of how it is used, which is why calibration and a certificate exist. Piston-operated apparatus is treated under ISO laboratory apparatus. The volume unit sits with the BIPM and NIST.
