Description
Varispenser® 2x, 0,5 – 5 mL is a single-channel bottle-top dispenser for accurate liquid dosing in laboratory workflows. It combines a recirculation valve with a telescopic suction tube of 125 – 240 mm length, allowing flexible adaptation to different bottle heights. The instrument carries a GL 45 standard thread that fits nearly all common laboratory bottle threads and is supplied with adapters GL 25, GL 28/S 28, GL 32, GL 38 and S 40. Safety valve balls integrated in the discharge valve prevent liquid escape when the discharge cannula is not connected. The pressure-equalisation valve cap can be unscrewed for straightforward mounting of a drying tube. An oval housing makes the unit easy to transport, while the PFA sealing lip of the piston reliably prevents jamming. Volume is set quickly and securely by a lockable slide on the internal toothed rail. All wetted components exhibit high chemical resistance. The dispenser is fully autoclavable without dismantling and offers optional user adjustment. This bottle dispenser from manufacturer Eppendorf is supplied as one piece with a net weight of 0,491 kg, supporting routine reagent handling across a wide range of applications.

Questions about Varispenser 2x, 0.5 - 5 mL
What is this article?
Varispenser 2x, 0.5 - 5 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.
