The Type 20 cell is designed for use in applications where a short path length and large window surface area is needed. This cell design is especially useful for opaque or viscose solutions. The cell consists of one fully fused component combining one window and the sides of the cell which forms the path length. The other window is separate and the cell can therefore be taken apart for cleaning. The cell wall and the removable window are polished so flat that the two will form a seal when
