Compatible with Eppendorf Research® 3 models set to the 20 µL range, the sleeve ensures smooth and complete tip ejection whether the pipette is used in variable or fixed-volume mode. Light-grey or yellow colour coding allows quick recognition of the correct part during pipette assembly or servicing.

The sleeve is produced by Eppendorf and supports uninterrupted daily pipetting work. Net weight is 0,005 kg and gross weight 0,006 kg, offering a lightweight spare that occupies minimal storage space. Manufactured in Germany, this laboratory material item is suitable for research, clinical and industrial laboratories that maintain Research® 3 single-channel pipettes and require reliable tip-ejection performance for precise liquid handling tasks.

Questions about Res.3 ej.sleeve vari/fix 20µL l.gray/yel
What is this article?
Res.3 ej.sleeve vari/fix 20µL l.gray/yel is the article on this page. Luminix Health distributes Eppendorf for laboratory use. It sits in Disposable coveralls & gowns, inside Protective clothing & workwear, in Lab safety equipment.
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.
