4.1 Inserting the cuvette
Prerequisites
• The cuvette is free from contamination from dust or finger prints and free from
scratches.
• Measuring volume in the cuvette is sufficient. Observe that the minimum measuring
volume has been reached.
• Measuring solution is free from particles and bubbles.
The direction of the light path is marked with an arrow along the upper edge.


Position the cuvette in such a way that the measuring window points towards the light
path.

During insertion, press the cuvette all the way down against a slight resistance.
4.2 Temperature control for kinetic measurements
For an efficient temperature control of the measuring solution during kinetic
measurements, the contact surface of the cuvette to the cuvette shaft must be as large as
possible.

Use the Eppendorf macro Vis Cuvettes for kinetic measurements
You can find notes on the temperature control of the cuvettes in the Eppendorf
BioSpectrometer kinetic in the operating manual of the device.
NOTICE! Material damage due to improper handling
The cuvette may fall if it is not handled properly. Liquid may spray out.

Store the cuvette in a cuvette stand.
NOTICE! Faulty measured values due to incorrect orientation of the cuvette.

Always insert the cuvette in the same direction within a series of
measurements. Do not rotate the cuvette 180° during a series of
measurements.
Do not touch the optical surfaces of the cuvette.
