221 Results for: "Test Strips"

Supplier: Hach

Test Strips that allow technicians in the field to test many samples in only a few minutes, and make immediate evaluations on-site.

Supplier: MACHEREY-NAGEL

QUANTOFIX® test strips meet all requirements of a modern rapid test. The colour of the reactive pad changes depending on the concentration of an analyte in the sample. The evaluation is usually carried out visually by comparison of the reaction colour with a multi-stage colour scale. These test strips are immediately ready to use. They do not require additional accessories. The test strips are intended for single-use, maintenance or calibration are not required.

Supplier: MACHEREY-NAGEL

Semi-quantitative test strips for reliable determination of chlorine concentrations as low as 0,05 mg/L (ppm). A hole in the plastic carrier allows the water to migrate through the test pad increasing the sensitivity by a factor of nearly 10. Ideal for rapid and easy analysis of chlorine directly on-site. No maintenance or calibration is required.

Supplier: MACHEREY-NAGEL

The test paper allows the quick and easy detection of Potassium. Rubidium, Cesium and Thallium(I) give the same reaction. Sodium and heavy metal ions decrease the sensitivity.

Supplier: MACHEREY-NAGEL

These test discs and reagent are for the semi-quantitative determination of fluoride ions. The fluoride test is especially suited for rapid control of fluoride concentrations. Its purpose is to define concentration ranges and to detect values which fall short of or exceed given limits.

Supplier: MACHEREY-NAGEL

Semi-quantitative test strips for reliable determination of total chlorine concentrations as low as 0,01 mg/L (ppm). A hole in the plastic carrier allows the water to migrate through the test pad, providing a high level of sensitivity. Ideal for rapid and easy analysis of total chlorine directly on-site. No maintenance or calibration is required.

Supplier: MACHEREY-NAGEL

This test paper allows the rapid and reliable detection of oil contamination of water and soil.

Supplier: MACHEREY-NAGEL

The test paper allows the quick and easy detection of silver ions. These cause red-violet spots on a salmon background. The leaflet describes a method to eliminate interferences of Hg, Cu, Au, Pt and Pd.

Supplier: MACHEREY-NAGEL

The test paper allows the rapid detection of fluoride ions in solutions containing hydrochlorid acid.

Supplier: MACHEREY-NAGEL

This test paper allows the quick and easy detection of Nickel.

Supplier: MACHEREY-NAGEL

This test paper allows the quick and easy detection of chromate (CrO_⁴^₃-). Cr(III) ions must be converted to Chromate prior to the detection.

Supplier: MACHEREY-NAGEL

This test paper allows the quick and easy detection of free halogens (Chlorine, Bromine, Iodine). Free nitrous acid HNO₂ (not nitrite ions) interferes, but can be destroyed by addition of amidosulphuric acid.

Supplier: MACHEREY-NAGEL

The test paper allows the quick and easy detection of sulphite and sulphur dioxide. In food analysis laboratories it is used to detect sulphite in meat products.

Supplier: MACHEREY-NAGEL

This test paper is used for the rapid detection of Iron ions (Fe₂⁺ and Fe⁺). In contrast to Dipyridylpaper it reacts with Fe(II) as well as Fe(III) ions. For the specific detection of Fe(II) please use Dipyridylpaper.

Supplier: MACHEREY-NAGEL

The test paper allows the easy determination of hydro sulphite (Sodium dithionite). It is used to determine the endpoint in the conversion of vat dyes to the leuco form. Because of the special purpose, indanthrene yellow paper is also called hydrosulphite paper.

Supplier: MACHEREY-NAGEL

This test paper allows the quick and easy detection of strong oxidisers such as Nitrite and free Chlorine. Potassium iodide starch paper is also used to control diazotisation reactions.

Supplier: MACHEREY-NAGEL

The test paper allows the quick and easy detection of boric acid and borates. It is impregnated with curcumin, the yellow dye extracted from the roots of Curcuma tinctoria (yellow ginger).
