5.2 Inserting the cuvette
Standard rectangular glass or plastic cuvettes can be inserted in the cuvette shaft:
• External dimensions: 12.5 mm × 12.5 mm
• Height of light path: 8.5 mm higher than cuvette base
• Total height: min. 36 mm
The cuvettes must be optically transparent for the respective measuring wavelength. For measurements in
the UV range, Eppendorf offers the plastic cuvette UVette which is transparent for wavelengths of 220
nm
and higher and therefore also is suitable for measuring nucleic acids.
Prerequisites
• The cuvette is free from contamination by dust or fingerprints and free from scratches.
• The cuvette shaft is free from particles, dust and liquid.
• The measuring volume in the cuvette is sufficient. Ensure that the minimum measuring volume has
been reached.
• The measuring solution is free from particles and bubbles.
• The cuvette temperature is above the temperature of the dew point that applies for the ambient
conditions (humidity and temperature).
1. Position the cuvette so that the optical window of the cuvette is pointing towards the direction of the
light path.
2. When inserting the cuvette, press it completely to the bottom against the slight resistance.
The direction of the light path is marked with an arrow on the housing.
