Installing and Calibrating an Aperture Tube
Calibrating the Aperture
2.
In the Aperture Options window:
a.
In the Calibrate using pane, select the basis for calibration (for example, the Mean Diameter
or Modal Diameter). Beckman Coulter recommends that you calibrate the system using the
standards on the assay sheet supplied with the calibrator.
b.
If you would like the Multisizer 4 software to prompt the operator to verify calibration at
regular intervals:
•
Select Verify Aperture Calibration.
•
In the Day(s) field, enter the number of days between reminders.
c.

Preparing the Analyzer for Calibration
To prepare the Analyzer for calibration:
1.
Fill a clean ST Beaker or Accuvette® ST with electrolyte solution.
NOTE
For aperture tubes up to 100 µm, you can use an Accuvette® ST (20 mL) and pre-filtered
ISOTON® II (see
Pre-Filtering the Electrolyte and Cleaning Fluid
, page
). Use an ST Beaker for any
aperture tube size larger than 100 µm.
2.
Add a few drops of the calibrator to the electrolyte solution.
3.
If necessary, use the platform release (page
) and lower the platform to the loading position.
4.
If necessary, turn the platform so that the correct side (with the ST Beaker or Accuvette® ST
guide) is on top (page
).
