Patent ID: 8663582

Claim:
An integral-type reaction cartridge used in magnetic separation of the process of purifying biomolecules, comprising: a plurality of reaction containers and at least one separation container, the integral-type reaction cartridge being characterized in that: the reaction containers and the at least one separation container are integrally formed of plastic and lined along a first direction, the at least one separation container having a first end, a second end opposing the first end, and a hollow accommodating space between the first end and the second end, wherein the first end is an open end, the second end is a closed end, and the accommodating space tapers from the first end to the second end, the accommodating space having a first side and a second side along the first direction, the accommodating space further having a third side and a fourth side along a second direction perpendicular to the first direction, wherein near the second end of the at least one separation container, at least one of the first side and the second side of the accommodating space has a lesser slope than the third side and the fourth side of the accommodating space; the first end of the at least one separation container is formed with an opening with a width along the first direction being greater than a width along the second direction; and the first side is changed from a curved configuration near the first end to a pointed configuration near the second end.
