.
Identifies the zeta cell fitted.
Depending upon the measurement to be performed, either a size or zeta
potential cell will be required.
When a zeta potential cell is inserted, the electrodes positioned on either
side of the cell holder will enable the type of cell to be detected
automatically. During the measurement the electrodes supply the voltage
necessary to perform electrophoresis.
If a size cell is inserted no electrode contact is made and the Zetasizer
assumes a size cell is fitted.

measurement.

Access for flow cell tubes
A channel incorporated into the cell area allows sample tubes to be connected to
the measurement cell. This facility is used with the MPT2 Autotitrator accessory.
The channel includes a pinch valve to hold the tubes in place and stop sample
movement during the measurement. To fit the tubes slide them into the channel
until clamped by the pinch valve.
A
Cell basin
The cell basin is made of an insulating material which provides protection from
the heated cell holder and in conjunction with the
Thermal cap

temperature stability when heating and cooling the sample.
A warning label indicates that high temperatures may exist in the cell area.

With the thermal cap removed both the metal lining of the the cap and
the top of the cell holder will be exposed. Care should be taken when
removing the cells after a measurement has been performed at high
temperatures. It is recommended that the cell area is allowed to cool
before removing the cell.
A
warning triangle is provided on the top of the cap.
