The most important criterion for the choice of a particular type of glass is the spectral range for which the cuvette is intended. 00029 for the standard 3. These electroporation cuvettes are made from clear, medical grade polycarbonate and are compatible with all common commercially available electroporators. The 13950 Shielded Cuvette Holder holds standard 10 x 10 mm cuvettes atop an optical rod. When in storage, the racks are stackable. A cuvette is a kind of laboratory glassware, usually a small tube of circular or square cross section, sealed at one end, made of plastic, glass, or optical grade quartz and designed to hold samples for spectroscopic experiments. It can be made of plastic for cheaper and disposable cuvettes right up to fused silica quartz glass. The HEMOCHRON Jr. These high-quality cuvettes are compatible with most electroporation systems, including Bio-Rad’s Gene Pulser MXcell™, Gene Pulser Xcell™, and MicroPulser Electroporators. They are also available through Fisher Scientific.
