Abstract: The present disclosure provides electroporation cartridges for single use electroporation as well as electroporation cartridges for automated batch processing, electroporation instruments and systems and methods of electroporation using these devices and systems. In some embodiments, electroporation cartridges comprise an electroporation chamber defined by an elongate body, a first electrode at a proximal end and a second electrode at a distal end of a chamber. Electroporation systems of the disclosure include one or more components including a pulse generator, compartments for placing either flow-through or single use electroporation cartridges, components for storage of cells, cooling and pre-cooling mechanisms, removably insertable modular casings having compartments for holding and arranging electroporation system and reagent components, one or more pumps for moving sample through the system, and processors and controllers.

Abstract: A device for inspecting microscopic objects. A plurality of LEDS is arranged in an array underneath a lens. Some of the LEDS are lighted and some of the LEDS are unlighted. A computer is in control of the LED array. The computer turns on selected LEDS from the array to form the lighted LEDS. Also, the computer turns off selected LEDS from the array to form the unlighted LEDS. The lighted LEDS form a pattern of lighted LEDS underneath the lens. In a preferred embodiment, the lens is connected to a computer controlled camera and the microscopic objects are microscopic crystals. In another preferred embodiment UV LEDS are utilized and illuminate crystals from above. In another preferred embodiment UV LEDS are utilized to illuminate a loop of a Hampton pin to locate a crystal in the loop of a Hampton pin for the purpose of x-ray crystallography.
