Description
Bottle-top dispenser without recirculation valve, 0,3-2 ml is a precision laboratory dispenser for reliable, bubble-free delivery of exact liquid volumes. Designed for uniform dispensing with high chemical resistance, it uses wetted components of PTFE, FEP, PFA and borosilicate glass. A springless PTFE valve block supports leak-free operation and a wiper-like piston action suited also to crystalline media, while the PTFE piston with Viton O-ring enables smooth, low-effort stroke movement. The dosing cylinder is protected by a polypropylene sleeve that helps contain glass fragments if breakage occurs. Large volume scales printed on both sides of the body allow quick, accurate reading; volume is set via a 180° adjustable rotary knob. The bottle adapter rotates 360° so liquid can be directed as needed, and a cap on the outlet tube limits air contact. Four neck adapters (28, 38, 40 and 45 mm) are included. Each unit from manufacturer ISOLAB Laborgeräte is individually calibrated to ISO 8655 with certificate and is autoclavable for demanding laboratory workflows.

Questions about dispenser - advanced - 2,5 ml
What is this article?
dispenser - advanced - 2,5 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.
