11.6.2.2 Test suspension for D 1 values

Prepare the test suspension for D1 values if the sample is probably non-toxic to
measure the sample toxicity using the highest possible sample concentration of 80%
(= D 1).

13.

Remove the pipette tips

from the pipettes and put in
the waste bag.

Put the pipettes in the

storage case.

Remove the Diluent

from the refrigerator.

bottle.

Put 20 parts Diluent

solution (D) at refrigerator
temperature into the
reaction vessel using a
pipette.

Remove the stock

solution (rehydrated
reagent) from the
refrigerator.
