Cuvette tests (Nanocolor)

A cuvette test contains a pre-dosed reagent in a round cuvette; you add the sample and read a quantitative value on a photometer. Choose it when you report results or follow trends, for example for COD, phosphate, nitrate or ammonium; instruments are in photometers and spectrophotometers. A test strip gives a quick, semi-quantitative indication on site, without an instrument, and suits screening; see test strips and indicator papers. Many labs use strips for screening and cuvette tests for the figures they record. Unsure? Ask sales@luminixhealth.com.

For one parameter, there are often several cuvette tests with different ranges. Choose the range in which your expected value falls roughly in the middle: readings at the edges of a range are less reliable. If your values are higher, dilute the sample with a defined factor or choose a test with a higher range; if they are lower, choose a lower range. The range is on each product page. For simple colour comparison without a photometer, see colorimetric test kits. Not sure which range fits your samples? Send typical values to sales@luminixhealth.com.

It depends on the parameter. Tests such as COD or total phosphorus need a digestion step at elevated temperature before you measure, so you need a thermoreactor or heating block that holds the cuvettes; suitable blocks are in hot plates and heating blocks. Direct tests, such as nitrate in many versions, need no heating and are read after a reaction time. The product page states whether, how long and at what temperature the cuvette must be heated; follow it exactly rather than general values. Unsure whether your test needs digestion? Ask sales@luminixhealth.com.

Round cuvette tests need a photometer with a matching cuvette shaft and the right wavelength, or a stored method for that test. Many photometers recognise tests by a barcode on the cuvette; others need the method entered manually. Check compatibility on the product page of the test, or send us the model of your photometer and the name of the test, and we will check it for you. If you are choosing a new instrument, compare the methods it supports in photometers and spectrophotometers. Send both names to sales@luminixhealth.com.

A cuvette test is a ready optical cell containing the reagents for one water or one chemical determination. The sample is added, the cell goes into a photometer, and the range printed on the box is the range of the answer. It is a method, packaged, not a bottle of reagent to assemble.

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.
