Beschreibung
Bottle-top dispenser without recirculation valve, 10,0–100 ml is a precision variable dispenser engineered for bubble-free aspiration and uniform liquid delivery. Autoclavable and calibrated individually according to ISO 8655, it is delivered with a calibration certificate and releases exact, reproducible volumes over its full adjustable range. Wetted components consist of PTFE, FEP, PFA and borosilicate glass for outstanding chemical resistance. The springless PTFE valve block guarantees leak-free performance and permits a wiper-style piston stroke that handles crystalline media reliably. Combined with a PTFE piston and Viton O-ring, the design offers high accuracy plus smooth, low-effort, fatigue-free piston travel. A polypropylene protective sleeve around the dosing cylinder retains glass shards in the event of accidental breakage. Dual large volume scales printed on both sides of the dispenser body enable rapid, precise reading. The adapter turns 360° on the bottle neck for flexible discharge direction, and a 180° rotary knob allows fast, secure volume adjustment. An outlet-tube cap limits air exposure and drying. Four adapters (28, 38, 40 and 45 mm) fit virtually all standard bottle openings. This version from manufacturer ISOLAB Laborgeräte is supplied without a recirculation valve.
This article is part of Bottle-top dispensers, in Liquid handling.

Questions about dispenser - advanced - 100 ml
What is this article?
dispenser - advanced - 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 Präzisionsinstrumente.
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.
