1.3.4 Dosing of sample and reagents
The exact dosing of the individual reagents is a precondition for the
successful carrying out of a test. The test sets contain simple accesso-
ries for correct dosing.
Instructions on using
dosing accessories pro-
vided with test sets
Precise dosing
of liquids
Exact dosing of the sample (and of certain reagents) is especially im-
portant. Use suitable laboratory pipettes for this.
Dropping bottles (liquid dosing)
Hold the dropping bottle in an exactly vertical
position with the dropping tip downward and
let the reagent drip out slowly so the correct
drop size forms.
Dosing tops/measurers (powder dosing)
Screw the dosing top on the reagent bottle
instead of the screw cap. For dosing, hold
the reagent bottle in a vertical position and
for each specified dose press the lateral slide
into the measurer up to the stop once. Sub-
sequently, close the reagent bottle with the
original screw cap so the contents cannot be-
come moist.
Microspoon (powder dosing)
Microspoons are integrated in the screw cap
of the reagent bottles. They are available in
several colors for several dosing quantities.
