Claim Text:
1. A perforating method for perforating a film covering a well provided in a reagent cartridge by using a dispensing device including: a dispensing head configured to suck and discharge a liquid; and a stage configured to support the reagent cartridge in which a reagent for biochemical analysis is enclosed, the perforating method comprising: mounting a perforating pipette tip on the dispensing head, the perforating pipette tip being formed by cutting a leading end of a pipette tip, that has the same shape as the dispensing pipette tip, along a plane inclined relative to a central axis thereof, and the perforating pipette tip having disposing the leading end of the perforating pipette tip mounted on the dispensing head, perpendicularly above the film; moving the dispensing head downward to stick the leading end of the perforating pipette tip into a film to form a hole in the film; and enlarging the formed hole by moving at least one of the dispensing head and the cartridge in a horizontal direction and tearing the film in the horizontal direction, in a state where the leading end of the perforating pipette tip is stuck into the film.
