Description
Disposable Pasteur pipettes with cotton plug are single-use laboratory pipettes intended for controlled liquid transfer. These long-type pipettes measure 230 mm in total length with a 120 mm tip and incorporate an integrated cotton plug. Supplied in packs of 250 pieces, they support routine handling of reagents and samples in analytical, chemical and life-science workflows where single-use glassware is preferred. The cotton plug helps retain particles and reduces splash-back during aspiration and dispensing. Their disposable design removes the need for washing or sterilisation cycles between uses, thereby limiting cross-contamination risk in multi-user environments. Produced by Witeg, the pipettes are suited to general laboratory liquid handling tasks that require a simple, ready-to-use Pasteur format. The pack net weight is 0,852 kg, making the units convenient to store and distribute across workstations. These pipettes fit standard laboratory practices involving aqueous solutions and many common organic solvents while maintaining straightforward operation without additional accessories.
This article is part of Pasteur pipettes, in Pipettes & pipette tips.

Questions about Pasteur pipettes disposable
What is this article?
Pasteur pipettes disposable is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Pasteur pipettes, inside Pipettes & pipette tips, in Lab consumables.
A Pasteur pipette is an uncalibrated glass or plastic transfer pipette. It moves a drop. It does not measure. Glass ones are pulled to a tip. Plastic ones are a single piece. Neither belongs in a result that needs a stated volume.
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.
