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 4mm cuvette has a wider gap for low field strength, used for mammalian and other eukaryotic cells. Comes with a distinguishing red cap. 4mm cuvette: minimum volume 80µl / maximum volume 800µl

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.
