Water quality testing doesn’t need to be complicated. Whether you’re working in municipal water treatment, industrial process control, environmental monitoring, or lab-based research, reliable and standardized testing methods are crucial. That’s where NANOCOLOR® photometric tube test kits by Macherey-Nagel, distributed by Vendart, step in.
Today, we spotlight three critical water testing kits that combine precision, simplicity, and speed—ideal for professionals looking for lab-grade reliability in every test:
NANOCOLOR® Carbonate Hardness Tube Test
NANOCOLOR® Chlorine Dioxide Tube Test
NANOCOLOR® Chloride Standard Test
For determination of alkalinity / acid-binding capacity / carbonate hardness
Key Details:
Test range: 1.25 – 18.75 °e (equivalent to 0.4 – 5.4 mmol/L H⁺)
Method: Photometric
Tests per kit: 20
Manufacturer: Macherey-Nagel
What It Measures:
Carbonate hardness—also referred to as alkalinity or acid capacity—represents the concentration of carbonate (CO₃²⁻) and bicarbonate (HCO₃⁻) ions typically associated with calcium and magnesium. This is a vital water parameter because it stabilizes pH and buffers against sudden acidity shifts.
Applications:
Municipal water treatment: Ensuring pH buffering and corrosion prevention
Aquaculture: Maintaining safe alkalinity levels for aquatic life
Industrial boiler and cooling systems: Avoiding scaling and corrosion
Environmental monitoring: Tracking acidification in natural waters
Why Choose This Kit:
Fast and reliable photometric detection
Easy-to-use tube test format—ideal for field or lab
Results correlate well with standard titration methods
For selective determination of chlorine dioxide
Key Details:
Test range: 0.15 – 5.00 mg/L ClO₂
Method: Photometric with DPD reaction (DIN 38408-G5)
Tests per kit: 20
Manufacturer: Macherey-Nagel
What It Measures:
Chlorine dioxide is a powerful disinfectant used widely in drinking water treatment, cooling towers, and food processing sanitation. Unlike chlorine, it doesn’t form harmful trihalomethanes, making it a preferred disinfectant in many settings.
This test uses a modified DPD (N,N-diethyl-p-phenylenediamine) method. With a specific supplementary reagent, it isolates chlorine dioxide and excludes free chlorine from the reaction—ensuring selective and accurate results.
Applications:
Drinking water disinfection monitoring
Cooling water systems
Beverage and food industry sanitation validation
Hospital and healthcare water systems
Why Choose This Kit:
DIN-compliant reaction mechanism
Distinguishes chlorine dioxide from free chlorine
Ideal for on-site or in-lab validation of disinfectant dosing
For rapid photometric determination of chloride ions
Key Details:
Test range: 0.2 – 125 mg/L Cl⁻
Method: Mercury(II) thiocyanate + iron(III) reaction (photometric)
Tests per kit: 250
Manufacturer: Macherey-Nagel
What It Measures:
Chloride is a major ion in natural waters and industrial systems. In drinking water, excessive chloride may cause corrosion of pipes and affect taste. In industrial processes, chloride can damage equipment and affect chemical reactions.
In this test, mercury(II) thiocyanate reacts with chloride to form mercury(II) chloride. The liberated thiocyanate forms a blood-red complex with iron(III)—measured photometrically for accurate chloride quantification.
Applications:
Drinking water analysis
Boiler feedwater monitoring
Food and beverage water testing
Environmental surface and groundwater studies
Why Choose This Kit:
High test capacity (250 tests per kit)
Wide dynamic range for varied water types
Clear, consistent coloration for reliable results
Why Use Photometric Tube Tests?
Unlike traditional wet chemistry or titration methods, NANOCOLOR® photometric tube tests offer:
Improved accuracy and reproducibility
Minimized reagent handling and waste
Compact, ready-to-use format
Reduced subjectivity with color interpretation
These kits are perfectly matched with NANOCOLOR® spectrophotometers, such as the NANOCOLOR Advance or NANOCOLOR VIS II, for rapid readouts and digital documentation.
