Lovibond Total Nitrogen VARIO LR

Lovibond Total Nitrogen VARIO LR is a low-range total nitrogen reagent set for photometric/tube testing of water, designed to determine total nitrogen concentrations in the low mg/L range. The set provides the chemical reagents and pre-dosed tubes required for acid/persulfate digestion and subsequent colorimetric measurement, intended for routine analysis of water samples where sensitive total nitrogen determination is required.

Key Features:

• Measurement range: 0–25 mg/L N (low range)
• Kit composition: VARIO TOTAL NITROGEN HYDROX. LR set, VARIO TOTAL NITROGEN HYDROX. LR tubes, VARIO TOTAL N PERSULFATE reagent, VARIO TOTAL NITROGEN ACID LR tubes, VARIO TOTAL NITROGEN Reagent A and Reagent B, deionised water
• Method: Acid/persulfate digestion with photometric/colorimetric evaluation (tube test)
• Format: Pre-dosed reagent tubes for VARIO/Tintometer photometers and tube-test workflows
• Pack configurations referenced by manufacturer/distributors (multiple pack sizes available)

Advantages:

• Pre-dosed reagents and ready-to-use tubes reduce handling and improve operator safety
• Low-range sensitivity suitable for precise monitoring of trace/low-level total nitrogen in water
• Designed for straightforward photometric evaluation, enabling faster routine analysis compared with manual reagent preparation
• Complete reagent set (digestion reagents plus color reagents and tubes) supplies all chemicals needed for the specified low-range method
