Care and Maintenance

The handling of photometer tubes is important to
ensure continuing accuracy. Scratches, finger-prints
and water droplets on the tube or inside the light
chamber can cause inaccurate results. It is imperative
that the tubes and light chamber are clean and dry.
The glassware must be clean and defect-free. Scratches
and abrasions will permanently affect the accuracy of the
readings. Tubes can be acid washed periodically.
Here are some hints on keeping the photometer clean,
free from contamination and in good working order :-
1 Prepare your workplace before use. Make sure that
you have enough space to work with the photometer
and with the reagent systems.
2 Do not pour out samples or prepare the tests
directly over the instrument.
3 Always cap the test tubes after preparing the blank
and test sample.
4 Wipe test tubes on a clean tissue to remove drips
or condensation before placing in the photometer.
5 Do not leave tubes standing in the photometer test
chamber. Remove the tubes immediately after each test.
6 Immediately wipe up any drips or spillages onto the
instrument or into the test chamber with a clean tissue.
