Description
Plunger collar and flange Proline Plus is a dedicated mechanical spare part for laboratory micropipettes in the Proline Plus family. This collar-and-flange assembly supports the plunger mechanism, helping maintain smooth stroke guidance and correct seating of the moving parts during routine pipetting work. Supplied as a single piece with a net weight of 0,002 kg and a gross weight of 0,003 kg, the component is intended for service, repair, or preventive maintenance of compatible instruments rather than as a consumable tip or reagent. Non-sterile by specification, it suits general laboratory environments where Proline Plus pipettes are used for liquid handling in research, quality control, and analytical workflows. The part originates from Finland and is offered from manufacturer Sartorius as an original-style replacement element for technicians who need to restore plunger alignment and flange integrity without exchanging the entire pipette body. Compact and lightweight, it integrates into standard pipette service procedures and supports continued accurate volume delivery when fitted according to the instrument’s maintenance guidance. Ideal for laboratories stocking genuine Proline Plus spares for in-house pipette care.
This article is part of Single-channel pipettes, in Liquid handling.

Questions about Plunger collar and flange Proline Plus
What is this article?
Plunger collar and flange Proline Plus is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Single-channel pipettes, inside Liquid handling, in Lab instruments.
A single-channel piston pipette delivers one volume through one tip. Fixed-volume pipettes are more accurate at their one volume. Variable pipettes cover a range and are specified at several points in it. Air displacement fails on viscous and volatile liquids.
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.
