Abstract: A system for separating an aqueous stream of mixed polynucleotides into a series of length-based polynucleotide fractions and collecting one or more of the length-based polynucleotide fractions into separate containers. The system comprises a separation column containing separation media for separating an aqueous stream of mixed polynucleotides into a series of length-based polynucleotide fractions; a container including one or more single-sample containers; an ejection chamber having a separated sample inlet for receiving the length-based polynucleotide fractions, a waste outlet for discharging uncollected sample, and a capillary-sized fraction outlet positioned to discharge a selected length-based polynucleotide fraction into a single-sample container. The system also includes means for effecting discharge of a selected length-based polynucleotide fraction into the separate container.

Abstract: Disclosed is a system and method which allows user controlled formation, and ejection of droplets of sample analyte containing solutions, thereby enabling precise user directed fractionalization and distributed collection of sample analytes.

Abstract: A gaming machine for distribution of a prize includes a display cabinet which includes a prize display section having at least one transparent surface for allowing exterior viewing of a prize held therein. Access doors are provided on the prize display section, the access doors being releasably locked in a closed position by a locking device. A random number generator generates a random number which is compared an input number input by a user through an input device such as a keyboard. A comparison device outputs a first signal if the random number and input number are equal, and a second signal if the random number and input number are unequal. If the comparison device outputs a first signal, the locking device disengages, thus providing immediate access to a prize held within the prize display section.
