Figure Lengend Snippet: Overview of the complete system, showing the Raspberry Pi touch screen, red housing, the three syringe pumps and the blue housing which holds the PCR tube cap. The first two syringe pumps are loaded with syringes. Not visible in the image are the microscope, Arduino microcontroller with motor control shield, microscope (mounted below the red platform) and the Raspberry Pi (mounted on the back side of the touch screen). Each syringe pump is comprised of a black stepper motor coupled to a lead screw that moves the syringe plunger up and down via the white housing, which is threaded on the lead screw.
Article Snippet: Next, the crystal(s) are prepared as follows. (i) A crystal pot is prepared by using a razor blade to separate a single transparent PCR tube cap from a strip of caps (for example catalog No. 27-110, Genesee Scientific, Morrisville, North Carolina, USA) and inverting the cap.
