For Sale BIO-RAD Gene Pulser and Capacitance Extender

Used for electroporation of bacteria primarily -- while their cell membranes are more permeable as a result of the process, plasmids can be introduced.

The Pulse Controller unit is used with the Gene Pulser apparatus for the electroporation ofbacteria, or for other applications where pulses of very high field strength are applied to samplesof small volume and high resistance. The Gene Pulser apparatus should not be used togenerate field strengths above ~6,000 V/cm unless it is connected to the Pulse Controller. Ifthe Pulse Controller is not used under these conditions, arcing may occur and cause seriousdamage to the Gene Pulser apparatus.The Pulse Controller greatly reduces the incidence of arcing at high voltages, and protects theGene Pulser circuit if a high voltage, high current arc does occur. The unit also allows the GenePulser apparatus to fire into a high resistance sample, and provides the operator with electroniccontrol of the time constant.The Pulse Controller should not be used with samples of less than 1,000 . This includes samplesof buffered saline (~20 ), tissue culture medium (~20 ), and phosphate buffered sucrose (~200). The internal resistance of the Pulse Controller will cause a substantial loss in voltage whenpulses are applied to low resistance samples. The voltage loss is insignificant with high resistancesamples (see Section 3 for a detailed discussion of this effect).
