Gene Pulser Capacitance Extender

Description (Brief)
This capacitance extender is part of the Gene Pulser, one of the first commercial electroporators. Manufactured by Bio-Rad, the Gene Pulser was on the market from 1986 to 1995.
Electroporation is a technique used to get drugs, proteins, DNA, and other molecules into cells. The method works by delivering a controlled electric pulse to cells in a solution. The pulse causes cells to briefly open pores in their cell membrane and take in molecules around them. The process is particularly useful in the creation of transgenic organisms.
This unit increases the capacitance of the pulse generator (object number 1998.0018.01) alone. Together, the two are recommended for electroporation of most eukaryotic cells, including mammalian and plant cells.
