Measurement
(continued)
The sample must be homogeneous and free of gas bubbles. Suspensions or emulsions may tend to
separate in the measuring cell and giving incorrect results. Make sure that such samples remain in the
measuring cell as briefly as possible. After taking a reading, clean and dry the measuring cell after each
measurement if samples with different chemical compositions are to be measured. For similar samples
(similar chemical composition and similar density) replace the previous sample by rinsing the measuring
cell with a sufficient amount (10 ml or more) of the new sample. Do not leave samples in the measuring
cell longer than necessary. Clean and dry the measuring cell as soon as possible.
Measuring with Syringe
Ensure that the syringe you are using is clean and dry. Fill it with a bubble-free sample. To remove the air
which is in the syringe, hold the syringe upright and press the plunger down slowly in the direction of the
needle until a drop of liquid is pressed out. Connect the syringe and push the sample from the syringe into
the device by pressing the plunger down slowly. From now on the Reichert DENSITY4/5 measures and
displays the density and other important measurements automatically.
