HELLMA｜Tray Cell
Feature :
- Easy handling – TrayCell always stays in the cell holder
- Excellent reproducibility of the measurement results
- Suitable for almost all standard UV/Vis spectrometers
- For sample volumes from 0.7 μl to 10 μl
- Also suitable for samples with low surface tension
- Different path lengths by means of exchangeable lids
- Long-term precise measurement results without follow-up and maintenance costs
High-tech on the smallest scale - with a patented operating principle
The TrayCell 2.0 comprises a fiber-optic measurement cell and a cap with integrated mirror. One drop (0.7 μl-10 μl) of the sample is pipetted onto the measuring window and then the corresponding cap with the selected path length is placed on top.
The light is guided via prism and optical fiber through the sample, reflected in the mirror and then guided via optical fiber and prism out of the TrayCell 2.0 to the detector.
The precisely defined spacing between the window and the mirror inside the cap ensures a precise and permanently consistent optical path length. The TrayCell 2.0 design makes expensive calibrations and readjustments unnecessary
