Install the 1-cm
square cell adapter.
Note: See Section 2.6 Sample
Cell Adapters in the Instrument
Manual for adapter installation
details.
Place the filled zeroing
cuvette into the cell
holder—arrow pointing

instrument.
Orient the arrow in the
same direction for all
cuvettes.
The Wiretrol Pipet can accurately measure small quantities of liquids. It consists
®
of two parts: a Teflon
-tipped plunger and a calibrated capillary tube. Use
Figure 1 to determine the quantity measured at each line on the capillary tube.
The plunger can be re-used; the capillary tubes must be discarded after one use.
