Description
Water ROTISOLV® Pestilyse® is a laboratory-grade solvent water prepared for gas chromatography and related analytical applications. With CAS number 7732-18-5 and empirical formula H₂O, it has a molar mass of 18,02 g/mol, a density of 1 g/cm³, and a boiling point of 100 °C. These fundamental physical properties match standard reference values for pure water used in chromatographic and sample-preparation contexts. The product is offered in a 2,5 l glass bottle from manufacturer Carl ROTH under the ROTISOLV® Pestilyse® designation within the GC solvents portfolio. Consistent quality supports dilution, blank preparation, and aqueous steps in methods that rely on a well-defined water matrix with low analytical background. EG number 231-791-2 complements the CAS identity for documentation and material control. Laboratories performing gas chromatography and associated workflows can integrate this water grade where a specified Pestilyse® solvent water is required for method robustness and routine analytical practice.

Questions about Water, ROTISOLV® Pestilyse®, 2.5 l, glass
What is this article?
Water, ROTISOLV® Pestilyse®, 2.5 l, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in GC liners, septa, syringes & accessories, inside GC columns & accessories, in Chromatography equipment.
A GC liner is the glass sleeve of the injector, and it collects the non-volatile residue. Its geometry, straight, gooseneck, with or without wool, belongs to a method. Septa and syringes are the other parts that leak. A liner for one injector model does not fit another.
A GC capillary column is a long open tube with a stationary phase coated on the wall. The sample is a vapour, carried by gas. The phase, the film thickness, the length and the internal diameter decide which compounds separate and how long it takes. A liner is the glass sleeve in the injector. It is a consumable: it collects the non-volatile dirt. The septum and the syringe are the other parts that leak or shed. Compound identity sits on PubChem under IUPAC names.
