Cleaning the Aperture Tube, Beakers, and Accuvette® STs
Before operating the Analyzer, rinse all system components and accessories in pre-filtered
ISOTON® II (see
Pre-Filtering the Electrolyte and Cleaning Fluid
CAUTION
•
If Beckman Coulter ISOTON
®
II is used, the Multisizer 4 must be drained and
flushed through with distilled water before carrying out a sodium hypochlorite
solution (bleach) disinfection procedure.
•
If the Multisizer 4 has been subjected to a bleach disinfection procedure, the
instrument must be drained and flushed through with distilled water before
refilling with ISOTON
®
II.
System components and accessories include:
•
Electrolyte Jar
•
ST Aperture Tube
•
External Electrode
•
Particle Trap
•
ST Beaker or Accuvette® ST
When handling Aperture Tubes and other system components, it is highly recommend that you
wear powder-free latex or nitrile gloves.
To clean the aperture tube and electrode:
1.
Press the platform release (
D
) towards the back of the Sample Compartment and
lower the platform to the loading position.
2.
Use a squeeze bottle filled with clean or pre-filtered ISOTON® II to rinse the aperture tube,
external electrode, and the stirrer (
, below).
3.
Select an ST Beaker that is at least one size larger than the size you used for the previous run
(or a 400-mL ST Beaker if you used that size for the previous run).
4.
Fill the clean ST Beaker with clean or pre-filtered ISOTON® II or de-ionized water (see
Filtering the Electrolyte and Cleaning Fluid
, page
). Make sure that the fluid level is higher
than the fluid level during the previous run.
5.
Lift the ST Beaker to immerse the aperture tube and electrode in the ST Beaker’s filtered liquid.
Swish to remove remaining particles.
6.
Place the ST Beaker on the platform below the aperture tube and allow remaining liquid to drip
into the ST Beaker.
