What is a Neutral Density Filter (NDF)?

A Neutral Density Filter is an optical filter that absorbs light of all wavelengths to the same extent. This means that if you look through an NDF it causes dimming but no change in colour. Therefore, they are very predictable when used us check standards in optical instruments. Being made of glass they are also stable and non-hazardous.

How do I clean my photometer?

Photometers should be regularly cleaned to ensure that your instrument is reading correctly and is not affected by dust or water marks.

To clean a compact or Lumiso photometer, place a small amount of anti- static cleaning foam on to a lint free cloth and wipe the instrument.

For multiparameter photometers, you should clean several parts of your instrument. To clean, place a small amount of anti- static cleaning foam on to a lint free cloth and wipe the instrument.

Sample holder.
The first image shows the surface around the sample holder, all visible marks on this area should be removed
Outside optics base plate.
Turn the instrument over and undo the two screws on the base of the instrument, as demonstrated in the second image. Gently wipe the curved areas near the LEDs and the flat area on the opposite side.
Inside optics base plate
Contamination on the inside of the base plate can migrate onto your calibration tubes leading to scratches which damage the standards. If marks cannot be removed from the base plate, a new base plate should be fitted.
When refitting or replacing a base plate, you must ensure screws are tightened so that the standards are set are the correct height. Failure to do so can lead to compromised results.

Can I recalibrate my photometer using check standards?

Check standards allow you to confirm that your instrument is reading results correctly.

The recalibration process is a highly technical process which is carefully controlled. To recalibrate your instrument, it must be returned to Palintest. Contact your Palintest representative for more information.
