Thin surgical stainless steel electrodes backed by water-ice temperature stabilizers provide a superior environment for cells-during electroporation. We make use of the latent heat of fusion of water (it takes the same number of calories to melt 1g of ice as to heat 1g of water 80°C!), so your sample stays cool, which is important to avoid arcing. Since the Pipectrode is a pipette, you can eject your sample into recovery buffer instantly.
