10 Cleaning and Storing the Instrument

10.1 Cleaning the Measuring Cell

Clean the measuring cell regularly before and after each measurement series with a
suitable solvent to ensure the long-term accuracy of your results. If the measuring cell
is not sufficiently cleaned, residue may form in the measuring cell and lead to
inaccurate measurement results. Depending on the application, also cleaning
between measurements may be required.
NOTICE
1. Place the filling tube in a vessel which is suitable for sample disposal.
2. Empty the measuring cell by pressing the pump lever.
3. Fill the measuring cell with a suitable solvent.
4. Pump the solvent through the whole measuring system several times.
5. Empty the measuring cell by pressing the pump lever.

10.2 Cleaning the Filling Pump

Clean the filling pump regularly, depending on your application. If you measure
aggressive samples, e.g. battery acid, clean the filling pump more often.
1. Place the filling tube in a vessel which is suitable for sample disposal.
2. Empty the measuring cell by pressing the pump lever.
3. Open the pump lock and remove the pump.
4. Rinse the pump under running tap water while moving the pump piston up and
down.
5. Dry the pump with a lint-free cloth.
6. Insert the pump and close the pump lock.
7. Empty the measuring cell by pressing the pump lever.

10.3 Cleaning the Pump Housing

DMA 35 is completely sealed against the outside and the pump. Therefore, you can
rinse the pump housing with running tap water if the housing is dirty.
1. Place the filling tube in a vessel which is suitable for sample disposal.

Make sure the solvent you use for cleaning is suitable. The DMA 35
pump cylinder is not resistant to aggressive cleaning liquids such as
acetone or methyl ethyl ketone (MEK).
