For use when preparing samples for photometric measurements
- removes turbid materials from samples
- differentiates between dissolved and total substances
- 0.45 μm mesh meets the requirements of the official German unitary procedure for water testing
To prevent the effects of light scatter, it must be ensured that all turbid materials are removed from the sample before photometric measurements are carried out. This can be achieved with the Lovibond membrane filter set.
Where certain methods are employed (e.g., iron, manganese, CSB, etc.) a membrane filter set must be used to differentiate samples in terms of dissolved and total substances. The filter mesh size of 0.45 μm is in accordance with the official German unitary procedure for water testing.
