RainDrop Carrier and Drive Oils
Aqueous samples are encapsulated within each droplet on the Source instrument,
surrounded by an immiscible carrier oil. The droplets are stabilized with surfactants allowing
for robust manipulation both on and off the chip. Precise control of carrier and drive oil flow
rates on the Sense instrument allows for control of droplet spacing. Use only RainDance-
supplied oils to avoid damage to the RainDrop System. The carrier oil and drive oil ports can
be filled with the oil provided in the Carrier Oil Syringe.
