21-I Series Standard Rectangular Infrasil Cuvettes with Stopper, 1-100mm

Type 21 cells are identical to Standard Rectangular or Macro cells, except that instead of having an open rectangular hole at the top, a block is fused to the top of the cell with a ground hole to receive a PTFE stopper. This provides a more suitable seal for volatile liquids. Cells with a path length of greater than 20mm are supplied with two stoppers and the height of the cell body is 48 mm with an overall height including the stopper of approximately 53mm.
