Modular reagent plate and reagent vessel kit

A modular reagent plate, comprising:

• a support rack comprising a frame and one or more separators, wherein each separator extends between two opposite end surfaces of the frame, and two ends of each separator are respectively connected to the two opposite end surfaces of the frame, and wherein the support rack includes a plurality of first slots, and each of the plurality of first slots being defined by at least the two opposite end surfaces of the frame and at least one of the separators;
• a reagent vessel with a plurality of second slots formed as one piece;
• and
• a base comprising a frame body, wherein the support rack is disposed on the frame body of the base and can be detachably combined with the base,
• wherein the reagent vessel further comprises at least two first fasteners positioned on at least one side surface thereof, the support rack further comprises at least two second fasteners, at least one of said at least two second fasteners is positioned on the one or more separators of the support rack, and the at least two first fasteners and the at least two second fasteners correspond to each other and can be joined together,
• wherein the at least two first fasteners are positioned at an upper part of the at least one side surface of the reagent vessel, and
• wherein a length of at least one of the plurality of first slots is greater than a length of the reagent vessel, and the first and second fasteners are configured to secure the reagent vessel in said at least one of the plurality of first slots without engaging an entire periphery of the reagent vessel.
