Beschreibung
Water finder test paper (7 m roll) is a laboratory test paper supplied as a continuous roll for detecting free water in non-aqueous media and related screening tasks. Each roll measures 7 m in length and 14 mm in width, allowing strips of convenient length to be cut for spot checks, field sampling or bench-side screening. The narrow format keeps reagent consumption low while remaining easy to handle with tweezers or gloved fingers. This water finder paper from manufacturer Macherey-Nagel is intended for qualitative indication work in quality control, maintenance and general laboratory practice where a simple visual response is required. The compact roll format stores neatly in drawers or field kits and supports repeated use from a single unit. Pack size is one roll, matching typical consumption for routine water-presence checks without excess bulk. Use according to established laboratory procedures for the matrix under test and interpret colour or wetting response under controlled conditions.
