The Eppendorf® Multiporator® basic unit is made up of a module designed to electroporate eukaryotic cells. This Eppendorf® Multiporator® includes one helix fusion chamber and one micro fusion chamber. It is used for eukaryotic cells and cell fusion. The fusion module expands the Multiporator®’s capabilities with highly efficient electrical cell fusion. Cells are brought into contact with one another in an electrical alternating-current environment and then fused with a direct-current pulse. Optimize your cell fusion parameters using the Electrofusion Buffer System with only a few cells in the Micro fusion chamber. When using the 0.2mm Micro fusion chamber, the ideal parameters determined in this way can be directly transferred to the cell fusion in the Helix fusion chamber. Eppendorf® Multiporator® applications for the module for cell fusion include generation of tetraploid blastocysts, cloning of mammals, fusion of plant protoplasts, generation of hybridoma cells for the production of monoclonal antibodies, fusion of lipid vesicles. It also features a space-saving inner device module, definable alignment and pulse parameters, square wave pulse, optimized buffer system, and a micro fusion chamber for optimization. Use the Eppendorf® Multiporator® for the electroporation of animal and human cells, primary cells, plant cells and embryonic stem cells, stable and transient transfection of eukaryotic cells, and efficient and gentle transfer of siRNA. The Eppendorf® Multiporator® is compact unit is easily portable, easy to disinfect, and easy to operate with clear, user-friendly display. It has outstanding safety levels provided by the built-in cuvette chamber, and is CE-, UL- and CAS-approved. Features connectors for external electrodes, directly adjustable voltage and time constants, and Soft Pulse technology. Soft Pulse technology applies extremely short electric pulses for the highest survival rates. Cell-damaging influences, such as changes in pH values, aluminum release and electrophoresis of the cell content, are minimized. The relevant parameters of voltage and pulse duration are directly set, and the patented electronic pulse discharge ensures that they will be maintained exactly—independent of the sample resistance—for reliable and reproducible results. Patented microprocessor controlled pulse discharge (U.S. Pat. 6,008,038). Two-year warranty. Eppendorf® #: 940000700.
