The CaF2 cell for IR/UV-CD spectroscopy is created between two perfectly flat, optically clear plates, the center of which is deepened to form a recessed parallel surface surrounded by a groove. The groove serves as a barrier between the sample area and the outer seal, keeping the sample
from coming into contact with the outer seal. The seal is created by the “upper” flat plate pressing onto the outer ring of the “lower” plate. The cells are very easily assembled and disassembled, filled with solution, and rinsed between measurements. The seal of the cell prevents the evaporation of water for about 24 h at room temperature. The reproducibility of the cell path length after assembly / disassembly is 0.1 μm
