Description
Bulb, ball Ø 72 mm is a large-format laboratory suction bulb for manual pipetting, featuring a ball diameter of 72 mm. With a net weight of 0,06433 kg and a gross weight of 0,069 kg, this size is suited to applications that benefit from a generous grip and higher displacement volume when aspirating and dispensing liquids with pipettes. The product is supplied in a pack of 10 pc(s) and is categorised under macro pipetting aids, Peleus balls, suction balls and pipette safety balls, confirming its function as a mechanical pipette aid. Origin is Germany. Offered by manufacturer Deutsch & Neumann, the 72 mm ball bulb complements smaller diameters in the same family and supports hand-operated liquid handling in research, teaching, production and quality-control laboratories. Clear diameter and mass specifications simplify selection against other ball sizes and help laboratories standardise on a preferred format for Peleus-style technique. The robust ball geometry is intended for repeated daily use as a replaceable consumable wherever classical suction-bulb pipetting remains the method of choice for controlled transfer of aqueous or other laboratory liquids.
This article belongs on Pipette stands, calibration & accessories, in Liquid handling.

Questions about bulb, Ball-Ø 72 mm
What is this article?
bulb, Ball-Ø 72 mm is the article on this page. Luminix Health distributes Deutsch & Neumann for laboratory use. It sits in Pipette stands, calibration & accessories, inside Liquid handling, in Lab instruments.
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.
