Description
Bottle-top dispenser with recirculation valve, 10,0–100 ml is a variable laboratory dispenser engineered for bubble-free aspiration and uniform, exact reagent delivery. Autoclavable and individually calibrated to ISO 8655 with a calibration certificate in the scope of supply, it provides precise and reproducible volumes over the 10,0–100 ml range. Wetted components of PTFE, FEP, PFA and borosilicate glass ensure high chemical resistance. A springless PTFE valve block delivers leak-free performance and a wiping piston motion suitable for crystalline liquids; the PTFE piston and Viton O-ring support smooth, low-force, fatigue-free operation. The dosing cylinder is shielded by a polypropylene sleeve that retains glass fragments in case of accidental breakage. Large volume scales printed on both sides of the body allow rapid, effortless and accurate reading. The adapter rotates 360° on the bottle neck for discharge in any preferred direction, while a 180° adjustable rotary knob enables fast and reliable volume adjustment. An outlet-tube cap limits air contact and drying. Four adapters (28, 38, 40 and 45 mm) fit virtually all common container openings. Equipped with a recirculation valve from manufacturer ISOLAB Laborgeräte, the unit avoids reagent loss during priming and rinsing cycles.

Questions about dispenser - advanced - with circulation valve - 100 ml
What is this article?
dispenser - advanced - with circulation valve - 100 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.
