6.6. Steriliser Cleaning
How to Prepare Steriliser Cleaning Fluid 1.
Mix 4 drops of the Steriliser Additive concentrate with 4 ml of de-ionised water
(1:20 ratio) in a sample tube with a Steriliser label. Replace the cap and mix well.
Remove the cap and introduce the tube to the viscometer along with the enzyme to
complete the daily maintenance. Discard any steriliser not used.
For each Steriliser cleansing process, the viscometer will take all of the mixed cleaner
from the „Steriliser‟ bar coded laboratory tube.
The concentrate is supplied in a 30 ml dropper container. We estimate this dropper will
last up to 6 months. The concentrate remains stable until it is mixed with water when it
then has a 14-day use by date. As the steriliser is only mixed when it is needed this
should not be an issue.
To Commence a Steriliser Clean 2.
A steriliser clean will be carried out when a tube displaying a „Steriliser‟ label is read by
the barcode reader on the viscometer. The probe will go into the steriliser tube and
extract all of Steriliser cleaning fluid. The fluid is retained in the Cassette, Upper
Manifold, and Upper Valves for approximately 1 minute (during this time the Steriliser
helps to minimise the risk of any harmful pathogen build-up).
The conveyor is then moved and the washpot comes forward and the probe lowered.
Steriliser fluid from the upper manifold is transferred to the washpot, drain line and
valve, and lower manifold, and held for 40 seconds (in 2 steps each of 20 seconds) to
work on the washpot.
This waiting period can be stopped at any time if necessary. However, this is not
recommended. If it is stopped the process should be repeated as soon as is
practicable.
