The Duroval C Titration Solution Refill Pack is a 50 ml replacement bottle for refilling your Duroval C test kit. Replacement solution for your test kit This is a titration solution for determining carbonate hardness or the m-value (acid capacity up to pH 4.3; KS 4.3) in all natural and technical water samples by titration. With the refill pack, you can replace the used-up titration solution in your existing Duroval C test kit. The solution is specially designed for determining carbonate hardness and ensures that the test kit can continue to be used. The refill bottle contains 50 ml of titration solution and is sufficient for approx. 200 analyses. The measurement time is approx. 2 minutes and the measurement accuracy is 0.5 °dH or 0.25 mmol/l. Work efficiently with the refill solution By using the refill solution, you do not need to buy a new complete kit and can carry out your analyses quickly without interrupting your testing routine.

The Duroval C Indicator 8 ml refill pack is a liquid colour indicator for use with your Duroval C test kit. It makes the point at which the reaction has finished visible, allowing you to read the carbonate hardness value. Liquid indicator for your Duroval test kit Refill pack: For determining carbonate hardness or the m-value (acid capacity up to pH 4.3; KS 4.3) in all natural and technical water samples by titration with a liquid titrant. The liquid indicator from this refill pack complements your existing Duroval C test kit, enabling you to measure carbonate hardness reliably. The indicator ensures that the chemical turning point in the titration is clearly visible, allowing you to read the measurement easily. Why the liquid indicator is important To determine the carbonate hardness or the m-value (acid capacity up to pH 4.3; KS 4.3) in all natural and industrial water samples by titration using a liquid titrant. The indicator is a crucial part of the measurement method, as it is only through its colour change that it is possible to recognise when the chemical endpoint of the titration has been reached. Without this colour change, it would be difficult to determine the carbonate hardness value.

The Duroval P Indicator 8 ml refill pack is a liquid indicator for use in Duroval titration test kits. It is used to analyse water samples as part of chemical titration procedures. Precise water analysis with Duroval P-Indicator 8 ml bottle of DUROVAL® P-Indicator refill bottle for determining water hardness across all hardness ranges. The Duroval P-Indicator supports reliable titration measurements in water samples. As a component of a Duroval test kit, it enables reproducible results in routine analyses. The refill bottle is easy to dispense and is designed to work with Duroval analysis systems. Suitable for: Water analysis using Duroval test kits Maintenance of water treatment and heating systems Laboratories and technical areas requiring regular water testing Not suitable for: Use without a suitable test kit Applications outside of chemical titration procedures Why is the correct indicator essential? The indicator is a crucial component of any titration measurement, as it is only through the indicator that the so-called endpoint becomes visible. Without it, the measurement result cannot be reliably determined. Even small deviations can lead to incorrect assessments of water quality or the condition of the system.

The replacement pipette for the measurement range 0–20° dH or 0–7 mmol/l is compatible with the Duroval C and Duroval CPM test kits. It is included in the test kit set but can also be ordered as a single item. Item numbers for the compatible test kits: Duroval C: 400060    Duroval CPM: 400065 What is this pipette suitable for?
