#90611 Nitratesmo

$51.00/roll of 5 m length and 10 mm width

This test paper allows the reliable detection of Nitrate and Nitrite. It shows different colors for the two ions.

 Instruction Sheet (pdf)
Color reaction: Nitrate: white → red (dip test paper into sample and afterwards into sulfuric acid 96%)
Nitrite: white → yellow (dip test paper into sample and afterwards into Hydrochloric acid 5 mol/l)

#91313 QUANTOFIX® Nitrate/Nitrite

$32.00/tube of 100 strips

These test strips are for the rapid and reliable determination of Nitrate and Nitrite in solutions. The easy dip-and-read-procedure of the test strips provides a reliable result within 1 minute.

QUANTOFIX® Nitrate / Nitrite test strips are the ideal choice to check nitrate and nitrite levels quickly and safely.

Color reaction: white → red-violet

#91351 QUANTOFIX® Nitrate/Nitrite 100

$36.20/tube of 100 strips

This test is the highly sensitive version of QUANTOFIX® Nitrate / Nitrite. It allows to detect nitrate down to 5 mg/L .
 Instruction Sheet (pdf)
Color reaction: yellow → red-violet
Shelf life:  at least 2.5 years

#931041 VISOCOLOR® ECO Nitrate

$50.00/kit (sufficient for 120 tests)

Nitrate is reduced to nitrite with an inorganic reducing agent. Nitrite is then diazotised with an aromatic amine and simultaneously coupled to form an azo dye.

 Instruction Sheet (pdf)
Shelf life: at least 1.5 years
Sea water suitability: yes Detectible with PF-12: yes

#90753 Potassium Iodate starch paper

$12.80/Roll of 5 m length and 7 mm width

The test paper allows the rapid detection of sulphit and sulphur dioxide. The paper is used in food analyzing laboratories. The reaction is as follows: 2 IO3- + 5 SO32- + 2 H+ → 5 SO42- + I2 + H2O
 
Color reaction: white → blue-black
