Immediately After Use: Clean the cuvette immediately after each measurement to prevent residues from sticking to the surfaces.
Non-Abrasive Cleaning: Avoid using abrasive materials or brushes on the cuvette, as this can scratch the surface and affect light transmission.
Handle with Gloves: Always handle the cuvette by its edges or frosted surfaces, not the optical windows, to avoid transferring oils from your fingers to the cuvette’s clear surfaces.
Periodically inspect the cuvette for any signs of cracks, scratches, or chips. Even minor damage can scatter light and affect the quality of your fluorescence measurements.
Scratches or Cracks: If you observe visible scratches, chips, or cracks on the cuvette, it’s time to replace it. Even small imperfections can scatter light and result in poor-quality fluorescence data.
Cloudiness or Haze: If the cuvette becomes cloudy or exhibits a haze that cannot be cleaned, this is a sign that the optical properties have degraded, and the cuvette should be replaced.
Persistent Contamination: If the cuvette retains residues or contaminants that are difficult to remove with normal cleaning, it’s better to replace it than risk contaminating future samples.
