The acid capacity – also referred to as KS4.3, alkalinity-M, total alkalinity or hydrogen carbonate acid – describes the concentration of hydrogen carbonate ions (HCO3–) dissolved in water. It influences the pH value and thus also the effectiveness of disinfectants or water care products. However, the acid capacity can also lead to material damage such as corrosion.
The Alka-M photometer tablet is used in photometers and spectrophotometers. Simply add the tablet to the water sample, crush it with the stirring rod, wait for the colour change and analyse it with the measuring device.
The BD 600 is a respirometric system for the determination of Biochemical Oxygen Demand (BOD). Save time, reduce the potential for errors and easily interpret data to help make process control decisions for your plant.
Automatic test recognition with internal barcode reader
Automatic cuvette type detection
Support of analytical quality assurance
The XD series instruments are ideal for routine and spectral analysis. As true all-rounders, the XD 7000 and XD 7500 facilitate work routines, especially with automatic method recognition using barcodes, automatic cell recognition and more than 150 pre-programmed methods. In addition to analytical quality control, they also support Good Labor Practice (GLP). The instruments are available together with bar-coded test tubes and a wide range of accessories from a single source – which is also easy on your wallet. High-quality reference beam optics, usability, easy handling and multilingual global applicability round off the versatility of the VIS and UV/VIS spectrophotometers, which are also equipped for flexible on-site use.
