Description
1-Ethyl-3-methyl-imidazolium bis(fluorosulfonyl)imide (EMIM FSI) is an electronic-grade ionic liquid with a minimum purity of 99,9 %. It carries CAS number 235789-75-0 and EG nr. 825-567-9, with empirical formula C₆H₁₁F₂N₃O₄S₂, a molar mass of 291,29 g/mol, and a density of 1,39 g/cm³. The imidazolium cation paired with the FSI anion is valued for ionic conductivity and thermal behaviour in non-aqueous electrolyte systems. Electronic-grade quality supports work where residual impurities must remain tightly controlled. Available from manufacturer proionic within the green chemicals and ionic-liquids range, EMIM FSI offers a defined composition for reproducible screening, scale-up trials, and analytical characterisation. Clear molar-mass and density data facilitate accurate dosing and solution preparation in performance-materials laboratories.

Questions about 1-Ethyl-3-methyl-imidazolium, bis(fluorosulfonyl)imide (EMIM FSI), 10 g, glass
What is this article?
1-Ethyl-3-methyl-imidazolium, bis(fluorosulfonyl)imide (EMIM FSI), 10 g, glass is the article on this page. Luminix Health distributes proionic for laboratory use. It sits in Electronic pipettes, inside Liquid handling, in Lab instruments.
An electronic pipette drives the piston with a motor, so a repeat dispense or a serial dilution is a program rather than the thumb. The volume range is still the specification. The battery and the modes, pipette, dispense, reverse, are the practical difference from a manual pipette.
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.
Which category should I open next?
The category is Liquid handling. The sub-category is Electronic pipettes. The catalogue is Lab instruments.
Shelves beside this one are Pipette stands, calibration & accessories, Single-channel pipettes, Bottle-top dispensers and Multichannel pipettes.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
