To measure the next sample, press the key again.

Sample dilution

Sample dilution in the measuring cuvette can be entered

using the key before the measurement begins and

is then included automatically in the result calculation

(see "Measuring diluted samples").

The OD 600 measurement is a stray-light measurement;

the result is therefore heavily dependent on the geometry

of the light path, which may vary between photometers

from different manufacturers.
