Recalibration of Liquid Filters

As is the case for all measuring devices, the liquid filters used to verify spectrophotometers must also be checked and recalibrated at regular intervals.

We recommend verifying and recertifying liquid filters within a maximum of 12 months. Intervals should be specified individually in accordance with your QM system.

Important!: Liquid filters may only be shipped when the outside temperature is above 4 °C, as the liquid can freeze and the reference materials will be destroyed as a result. - Please note that from November to March liquid filters should only be shipped by express delivery.
