Description
Varispenser® 2 is a single-channel bottle dispenser intended for controlled liquid delivery in the 5 – 50 mL working range. Its telescopic suction tube extends from 170 to 330 mm, enabling quick adjustment to varying bottle heights. The dispenser is built around a GL-45 standard thread and includes adapters GL 32, GL 38 and S 40, so it mounts securely on most common laboratory bottles. Safety valve balls inside the discharge valve block unintended liquid release when the discharge cannula is not fitted, and the cap of the pressure-equalisation valve can be removed for easy installation of a drying tube. An oval housing design aids comfortable handling and transport, while the PFA sealing lip of the piston minimises jamming risk. Volume setting is performed by a lockable slide on the internal toothed rail for rapid, reproducible adjustment. Components participating in the dosing process show high chemical resistance. The fully assembled instrument from manufacturer Eppendorf is completely autoclavable without prior disassembly, supporting efficient use in research and quality-control environments.

Questions about Varispenser 2, 5 - 50 mL
What is this article?
Varispenser 2, 5 - 50 mL is the article on this page. Luminix Health distributes Eppendorf 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.
