Abstract: A dispensing tip holder is used when a dispensing tip is attached to a tip of a pipette, and includes a peripheral wall having a shape surrounding an outer peripheral surface of the dispensing tip, and an insertion portion having an insertion opening into which the dispensing tip is to be inserted. The peripheral wall has a first end into which the dispensing tip is to be inserted, and has a second end provided at a position opposite to the first end. The insertion portion is formed in the peripheral wall such that an outer peripheral surface of the dispensing tip abuts against an edge of the insertion opening, and is formed in the peripheral wall such that a tip of the dispensing tip does not project from the second end of the peripheral wall, when the dispensing tip is inserted into the insertion opening from the first end.

Abstract: To improve a sealing property of a reaction container over a period before and after implementing gene amplification processing. A gene amplification device includes: a reaction container holder having a container insertion part into which a main body of a reaction container including the main body and a lid attached to an upper portion of the main body is inserted, the reaction container holder having a function of raising and lowering a temperature of the reaction container inserted into the container insertion part; and a heat seal part disposed near an contacting portion between the main body and the lid of the reaction container inserted into the container insertion part of the reaction container holder, the heat seal part heating a temperature of the contacting portion to a temperature higher than a heatproof temperature of the main body or the lid of the reaction container.
