Lovibond COD Vario Tube Test 0–150 mg/L

The Lovibond COD Vario Tube Test 0–150 mg/L is a ready-to-use sealed tube reagent designed for the photometric determination of Chemical Oxygen Demand (COD) in water and wastewater samples. This product is the Low Range (LR) COD Vario tube test and is suitable for samples with COD concentrations from 0 to 150 mg/L.

Lovibond COD Vario tube tests use the dichromate method and are designed for use with compatible Lovibond photometers. The 0–150 mg/L range is particularly useful for water and wastewater samples where COD concentrations are relatively low and accurate measurement within the lower range is required.

What is COD?

Chemical Oxygen Demand (COD) is a commonly used water-quality parameter that indicates the amount of oxygen required to chemically oxidize oxidizable substances present in a water sample.

COD testing is widely used in water treatment, wastewater monitoring, environmental analysis, industrial laboratories, and research facilities. Measuring COD helps laboratories assess the level of chemically oxidizable substances in water and wastewater.

The Lovibond COD Vario system determines COD through a digestion process followed by photometric measurement using a compatible photometer.

How the Lovibond COD Vario 0–150 mg/L Test Works

The Lovibond COD Vario tube test uses a sealed reaction tube containing the required reagents for the COD determination. A measured quantity of the water sample is added to the appropriate reaction tube according to the manufacturer’s test procedure.

The prepared tube is then securely closed and mixed carefully. The sample undergoes a controlled digestion process in a suitable thermoreactor. During digestion, oxidizable substances in the sample react with the chemical reagents.

After digestion, the reaction tube is allowed to cool before photometric measurement. The processed tube is then placed into a compatible Lovibond photometer, where the COD concentration is determined based on the photometric reaction.

Because COD testing involves chemical reagents and elevated temperatures during digestion, appropriate laboratory safety procedures, protective equipment, and manufacturer’s instructions should always be followed.

Applications

The Lovibond COD Vario Tube Test 0–150 mg/L is suitable for:

• Water Quality Testing
• Wastewater Testing
• Environmental Water Monitoring
• Laboratory Water Analysis
• Industrial Process Water Testing
• Wastewater Treatment Monitoring
• Research and Analytical Laboratories
• Municipal Water Treatment Applications
• Environmental Monitoring Programs

The low-range format is particularly useful when the expected COD concentration of the sample falls within the 0–150 mg/L measurement range.

Compatibility

The 0–150 mg/L COD Vario tube test is designed for use with compatible Lovibond photometers that support the corresponding COD Vario method.

Before purchasing or using the tubes, users should confirm compatibility with their specific photometer and thermoreactor. Following the manufacturer’s recommended procedure helps ensure reliable and repeatable COD measurements.
