1. A sampling container apparatus comprising:
a motor housing comprising a motor configured to rotate at least one magnet around a drift shaft of the motor;
a magnetic plate configured to magnetically couple to the at least one magnet of the motor housing, the magnetic plate configured to rotate in unison with the at least one magnet of the motor housing;
a shroud housing configured to enclose at least some of the motor housing and the magnetic plate;
a sample container housing configured to be placed within the shroud housing and mechanically connected to the magnetic plate, the sample container housing including
a tank configured to hold a sample within an interior chamber, the tank including a first end having a first opening to the interior chamber and a second end having a second opening to the interior chamber, and
a plunger having a shaft positioned within the interior chamber, the plunger having a first cup at a first end configured to seal the first opening of the tank and a second cup at a second end configured to seal the second opening of the tank, the shaft connected to the first end and the second end of the plunger and configured to pull the first end and second end of the plunger toward each other;
a first retainer plate located above the first end of the tank, the first retainer plate including
a first plunger window configured to enable the first cup of the plunger to pass through, and
a first travel channel connected to the first plunger window, the first travel channel having a width that is larger than the shaft and smaller than the first cup of the plunger; and
a second retainer plate located below the second end of the tank, the second retainer plate including
a second plunger window configured to enable the second cup of the plunger to pass through, and
a second travel channel connected to the second plunger window, the second travel channel having a width that is larger than the shaft and smaller than the second cup of the plunger,
wherein the first and second retainer plates are configured to retain the plunger in an open position until the sample container housing is rotated by the motor, causing the sample container housing including the plunger to rotate relative to the first and second retainer plates along the first and second travel channels such that the first cup passes through the first plunger window and the second cup passes through the second plunger window when the cups are aligned with the respective windows, thereby enabling the plunger to actuate to a closed position and causing the first cup to seal the first opening of the tank and the second cup to seal the second opening of the tank.
