What material is this made out of? Other than SKU# U-72004, do you sell any cuvettes with a path length shorter than 10 mm?

The metal component of the cuvette is polished aluminum, while the plastic component is polystyrene. We do not currently have any non-standard size electroporation cuvettes. The sizes we currently carry are 10mm, 20mm, and 40mm which is the standard size for electroporators.
