7.2.13 Cleaning the reagent vessels
1. Remove the reagent vessels individually from the load drawer by the handle. Ensure that the
handle is in the correct position
P. 37 – 4.6.3 Prepare the reagent vessel, fill it and insert it
to prevent spilling the reagent.
2.
Dispose of filled reagents in accordance with the local laboratory specifications.
3.
All reagent vessels can be cleaned in a dishwasher at a maximum temperature of 65 °C using
a standard, commercially available detergent for lab dishwashers. The handles can remain
attached to the various vessels when doing so.
Warning
•
Reagent vessels are to be pre-cleaned manually before cleaning in a dishwasher. Any staining
residue that may be present is to be removed to the greatest extent possible to prevent
discoloration of the remaining reagent vessels in the dishwasher.
• Never clean plastic reagent vessels at temperatures higher than 65 °C since this can deform
reagent vessels!
7.2.14 Rack and handle
L
The racks are to be checked regularly for mounting medium residue and other possible
contamination.
1. The colored handle must be removed from the rack for cleaning.
2. To remove small amounts of residual mountant, soak a lint-free cloth with xylene and clean the
racks.
3. For stubborn dirt, you can place the racks in a xylene bath for up to 1–2 hours to remove dried
out residual mountant.
4. The xylene can then be washed off with alcohol.
Completely rinse the racks with clean water and then dry them.
L
A dishwasher can also be used for the cleaning process. The maximum temperature of 65 °C must
be observed.
Note
The maximum exposure time in a xylene bath is 1–2 hours. Completely rinse the racks with water, then
dry them. If an external oven is used for drying, the temperature must not exceed 70 °C.
Warning
•
The racks and handles may not remain in the xylene for a long time frame (e.g. several hours or
overnight), because this can lead to deformation!
