Operation - Hellma Analytics TRAYCELL 2.0 Schnellstartanleitung

OPERATION

 The TrayCell is a fiber-optic, microvolume measuring cell and was developed
for the UV-Vis analysis of proteins and DNA/RNA. To enable its use in a
majority of spectrophotometers, the TrayCell's dimen-
sions are the same as those of a standard cuvette.
 First check the center height required for your spectrophotome-
ter and ensure that the TrayCell is set to the correct center height.
 Position the TrayCell in the cuvette holder with the window facing in the
direction of the light path. We recommend placing the Hellma lo-
go at the front. Always insert the TrayCell in the same direction.
 Maximum TrayCell performance is achieved when the light beam that
passes through the measuring chamber has a diameter below 4 mm.
 The TrayCell must be correctly inserted into the cuvette holder for measure-
ments to be performed. Please ensure that the TrayCell is firmly seated in
the cuvette holder and does not wobble! It should then remain in
the cuvette holder for the duration of all sample measurements and
cleaning processes carried out within a measurement series.
 The TrayCell should not be moved at all (removed and re-inserted) during a
series of measurements.
The TrayCell is supplied with a center height of 8.5 mm. If you need to
adjust the center height, please use the relevant adapter. This is supplied
with appropriate screws. Screw the adapter into the pre-drilled holes on
the TrayCell from below.
