  • Devices and methods for producing ice beads from an aqueous mixture
    Patent number: 8720211
    Abstract: The present invention relates to a device (1) for producing ice beads (10). The device (1) comprises at least one cooling device (18) for cooling a hydrophobic liquid (20) to a temperature of at least ?5° C. and a receiving vessel (2, 102) having the hydrophobic liquid (20). Furthermore, the device (1) comprises a pipetting device (3) situated on the receiving vessel (2, 102), which comprises a vessel (4) for an aqueous mixture (11). A plurality of tapering outlet tubes (5) extends therefrom, which is situated in a vessel wall (4?), into the receiving vessel (2, 102). An outlet end of an outlet tube (5) is situated spaced apart in the range of 3 cm to 10 cm from a surface (20?) of the hydrophobic liquid (20). Furthermore, the device (1) comprises at least one apparatus for providing a relative velocity between the pipetting device (3) and the hydrophobic liquid (20).
