These objects are parts 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.
The tan box with the black display seen in the first photo is the pulse generator, the part of the Gene Pulser that produces the electric pulses for electroporation. The white chamber seen in subsequent photos is the shocking chamber, used to hold samples for electroporation.
