Glass cuvettes

LLG-Cuvettes are most frequently used in analytical laboratories.

They have two clear windows, two side walls and are available as optical glass or quartz variants. The walls and the base are polished inside and frosted outside. The thickness of the windows and the base is 1.25 mm. The overall height of standard type cells is 45 mm or 48 mm for those fitted with a stopper. Each cuvette is supplied with a PTFE lid.
