Gene Pulser™ and MicroPulser™ Cuvette
Electroporation Cuvettes
Tariff classification of the Gene Pulser™ and MicroPulser™ Cuvette. The merchandise at issue is a cuvette, which is a small tube with a circular or square cross section that is sealed at one end to hold samples for spectroscopic experiments. The cuvettes are made of plastic, contain aluminum electrode plates, and have caps. The cuvettes are used solely with electroporation machines and are specifically designed to work with two models of Bio-Rad electroporation machines: the Gene Pulser™ and the MicroPulser.™ The Gene Pulser™ and MicroPulser™ electroporation machines have specifically designed cuvette chambers, which enable the cuvettes to be inserted directly into the electroporators. Electroporation is a technique used in microbiology to create pores in cell membranes by applying an electrical field to increase the permeability of the cells and allowing for the introduction of a substance into the cell. Cells are suspended in a liquid and are placed within the cuvette. The cuvette is placed in the electroporator. There are electrical contacts within the electroporator that make contact with the electrodes on the side of the cuvette. The electroporator creates an electro-magnetic field in the cell solution, which allows substances such as chemicals, drugs, or DNA to be introduced into the cells.
