Genesee brand electroporation cuvettes' high-grade aluminum electrodes are produced through a unique manufacturing process which ensures a scratch-free surface for uniform pulse delivery to the entire sample. The 1mm cuvette has the narrowest gap and shallow bottom for small sample volumes (40–80 μl) and very high field strength, used for yeast and bacterial transformation. Comes with a distinguishing white cap. 1mm cuvette: minimum volume 20μl / maximum volume 90μl

Cuvettes are available in three gap widths: 1mm, 2mm, and 4mm, to deliver the proper field strength to a variety of cell types. Use the 1mm cuvette to deliver pulses with the highest field strength, up to 25 kV/cm, for the high-efficiency electrotransformation of E. coli and other bacteria. For yeast transformation, generate pulses with a field strength up to 12.5 kV/cm using the 2mm cuvette. Mammalian cells typically require field strengths up to 6.25 kV/cm, which can be achieved using the 4mm cuvette.
