Description
QUANTOFIX Relax is a reflectance photometer for the evaluation of QUANTOFIX test strips in laboratory and environmental analytics. This single-unit instrument provides objective optical readout of strip colour reactions, supporting consistent documentation of semi-quantitative and quantitative strip results. The package includes a power supply, adapter plugs, handbook, one roll of printer paper and a certificate, so the device is ready for routine bench use once connected. With a net weight of 1,65 kg and compact outer dimensions, the photometer fits easily into standard laboratory workspaces. Offered by manufacturer Macherey-Nagel, QUANTOFIX Relax is intended for laboratories that already work with the QUANTOFIX test-strip portfolio and need a dedicated reader for controlled evaluation. Typical applications include environmental monitoring, process checks and quality-control workflows where strip tests must be read under defined optical conditions. The single-unit configuration supplies the instrument and essential accessories without additional strip reagents, which are selected separately according to the parameter under investigation.

Questions about QUANTOFIX Relax / single device
What is this article?
QUANTOFIX Relax / single device is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Colorimetric test kits, inside Test kits & water analysis, in Lab chemicals.
A colorimetric kit develops a colour whose intensity tracks concentration. Comparing by eye against a chart and reading a photometer are different versions. The range, the sample volume and the interfering substances named in the leaflet are the specification.
A test kit turns a chemical question into a colour, a titre or a reading on a strip, so the operator does not have to assemble the method from separate reagents. A cuvette test is a ready optical cell. A strip is a field reading. The range printed on the kit is the range where the answer means something. Outside it, the kit is silent or wrong. The substances inside are on PubChem. Water measurement traces to NIST.
