biosystems BA 400 - Scales, Bottles And Tanks; Scale Adjustment For Determining Level

Stability
is verication takes measurements in all the wavelengths for 30 minutes. It is used to verify the stability of the
photometric readings
After taking the measurements it shows the following parameters for each wavelength:
• Mean
• Standard deviation of all measurements
• Coecient of variation
• Maximim absorbance
• Minimum absorbance
Absorbance reading
is allows you to measure the aborbance of a selected well.
6.5.3. Scales, bottles and tanks
6.5.3.1. Scale adjustment for determining level.
e levels of the washing solution and high contamination waste bottles are determined by weighing. To adjust the
scales, proceed as follows:
Washing solution bottle adjustment
1. Put the full washing solution bottle in place.
2. Press the FULL adjustment button.
3. Put the empty washing solution bottle in place.
4. Press the EMPTY adjustment button.
5. Save the results
High contamination waste bottle adjustment
1. Put the full waste bottle in position.
2. Press the FULL adjustment button.
3. Put the empty waste bottle in position.
4. Press the EMPTY adjustment button.
5. Save the results
Final verification of the washing solution and high contamination waste bottle levels
To verify whether the bottle level adjustment is correct, place a known level of uid in the washing solution or waste
bottle and check that the value shown on the screen (see Figure 6.16) inside the bottles matches the real bottle level.
