Description
Bottle-top dispenser with recirculation valve, 2,5-30 ml provides dependable bubble-free aspiration and uniform delivery of exact reagent volumes. The instrument is autoclavable and individually calibrated to ISO 8655; a calibration certificate accompanies every unit. All parts in contact with liquid are fabricated from PTFE, FEP, PFA and borosilicate glass, conferring high chemical resistance. Its springless PTFE valve block guarantees leak-free operation and a wiping piston motion well suited to crystalline solutions. A PTFE piston paired with a Viton O-ring yields high volumetric accuracy together with smooth, low-force, fatigue-free stroking. The dosing cylinder is enclosed in a polypropylene protective sleeve that contains glass splinters in the event of breakage. Clearly printed dual-sided volume scales enable fast and precise reading from either side. The bottle adapter turns freely through 360°, allowing discharge in any convenient direction, while the 180° adjustable rotary knob simplifies volume selection. A cap fitted to the outlet tube minimises air contact and drying. Four adapters with diameters of 28, 38, 40 and 45 mm accommodate nearly every common bottle neck. This version from manufacturer ISOLAB Laborgeräte is equipped with a recirculation valve that prevents loss of valuable reagent during rinsing.
This article is part of Bottle-top dispensers, in Liquid handling.

Questions about dispenser - advanced - with circulation valve - 30 ml
What is this article?
dispenser - advanced - with circulation valve - 30 ml is the article on this page. Luminix Health distributes ISOLAB for laboratory use. It sits in Bottle-top dispensers, inside Liquid handling, in Lab instruments.
A bottle-top dispenser meters a reagent directly from the bottle it is mounted on, by a piston. The volume range and the chemical compatibility of the wetted parts, glass, ceramic, PTFE, are the specification. It is for the same reagent again and again, not for changing liquids every sample.
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.
