Description
Research 3 ejection sleeve vari 300 µL orange is a tip ejector sleeve made for Eppendorf Research® 3 single-channel pipettes with a 300 µL volume capacity. The orange colour code corresponds to the 300 µL models, while the vari designation marks it for variable-volume instruments. Replacing a worn ejector sleeve restores secure tip ejection and helps maintain the pipette’s intended performance in routine liquid-handling tasks. The component is supplied as a single piece weighing 0,005 kg net and 0,006 kg gross. It originates from manufacturer Eppendorf in Germany (Hamburg region) and mounts directly on compatible Research® 3 single-channel pipettes without changing ergonomics or the established colour-coding scheme. Laboratories employ these sleeves in molecular biology, clinical diagnostics and general research settings where reliable tip release is essential. The accessory belongs to the pipette spare-parts category and is listed under the relevant UNSPSC laboratory classification. Packaging volume and related logistics details are recorded in the technical product data.

Questions about Res.3 ejector sleeve vari 300µL orange
What is this article?
Res.3 ejector sleeve vari 300µL orange is the article on this page. Luminix Health distributes Eppendorf for laboratory use. It sits in Disposable coveralls & gowns, inside Protective clothing & workwear, in Sécurité.
A coverall or a gown covers more of the body than a coat. The type rating, where one is claimed, describes the kind of hazard the fabric was tested against. A visitor's thin gown and a chemical protective coverall are different products. Seams and the hood are part of the rating.
Workwear is the layer between the person and the room. A lab coat is the ordinary coat. A coverall is what is worn when the coat does not cover enough. Cleanroom garments are about the particles the person sheds, not only about the splash. Radiation and hearing protection are specific physical hazards with their own ratings. The rating, not the colour, is the specification. Equipment placed on the EU market follows the PPE Regulation. Practice is at EU-OSHA on dangerous substances.
