Specifications

According to standard: DIN 38409-H23-2
EPA compliant: N/A
Instrument: DR3900, DR6000, DR1900
Measuring range: 0.1 - 20 g/L
Method: CTAS
Number of tests: 25
Parameter: Surfactants, nonionic
Platform: LCK
Sample requirements: The pH of the water sample must be between pH 3-9.
Due to the high salt content of acidic or alkaline degreasing baths, the pH must be adjusted to 7-8.
Acidic degreasing baths with a high iron content should not be neutralized, as this would cause precipitation of iron hydroxide, which can absorb large amounts of surfactant. In such cases it is advisable to carry out a preliminary extraction with ethyl acetate, or to dilute the sample appropriately (1:100-1:500) and use the Cuvette Test LCK333.
Storage conditions: 15 - 25 °C
