The rinse program is a pre-installed program.

After the dehydration program is completed, the rinse program will be given

cannot be cancelled.
Use only recommended rinse reagents.
Do not open the dehydration cylinder lid during the drying procedures of the rinse
program.
Do not pull out the reagent bottle during the operation of the rinse program. Such

The sample baskets can be cleaned together in the dehydration cylinder. Only the
sample baskets that have gone through standard rinse can be used for dehydration.
Xylene for rinse and alcohol for rinse are recommended to be replaced after 5 times of
rinse, otherwise it will affect the dehydration effect.
