Abstract
Abstract A dry frameless chemical analysis film includes a support sheet and a reagent layer formed on the support sheet. An incubator for incubating the film spotted with a sample liquid includes an incubator base on which the frameless chemical analysis film is placed, an incubator cell member which is movable up and down between a lower position and an upper position and presses a part of the upper surface of the frameless chemical analysis film against the incubator base while tightly enclosing a space around the frameless chemical analysis film in the lower position, and a first heater which heats the part of the incubator base with which the frameless chemical analysis film is brought into contact to a first predetermined temperature and holds the same at the first predetermined temperature, and a second heater which heats the incubator cell member to a second predetermined temperature higher than the first predetermined temperature.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
194 words
An incubator for incubating a dry frameless chemical analysis film which comprises a support sheet and a reagent layer formed on the support sheet and is spotted on an upper surface with a sample liquid, the incubator comprising: an incubator base on which the frameless chemical analysis film is placed, an incubator cell member which is movable up and down between a lower position and an upper position and presses a peripheral portion of the upper surface of the frameless chemical analysis film at a location outside of the sample liquid against the incubator base while also enclosing a space around the frameless chemical analysis film in the lower position, a first heating means which heats the incubator based at least at a location in which the frameless chemical analysis film is brought into contact with the incubator base when the incubator cell member is in the lower position, to a first predetermined temperature and holds the incubator base and in turn the frameless chemical analysis film at the first predetermined temperature, and a second heating means which heats the incubator cell member to a second predetermined temperature higher than the first predetermined temperature.
Claim 2
Dependent Claim
194 words
An incubator for incubating a dry frameless chemical analysis film which comprises a support sheet and a reagent layer formed on the support sheet and is spotted on an upper surface with a sample liquid, the incubator comprising: an incubator base on which the frameless chemical analysis film is placed, an incubator cell member which is movable up and down between a lower position and an upper position and presses a peripheral portion of the upper surface of the frameless chemical analysis film at a location outside of the sample liquid against the incubator base while also enclosing a space around the frameless chemical analysis film in the lower position, a first heating means which heats the incubator based at least at a location in which the frameless chemical analysis film is brought into contact with the incubator base when the incubator cell member is in the lower position, to a first predetermined temperature and holds the incubator base and in turn the frameless chemical analysis film at the first predetermined temperature, and a second heating means which heats the incubator cell member to a second predetermined temperature higher than the first predetermined temperature.
Claim 3
Dependent Claim
25 words
An incubator as defined in claim 1 in which said second predetermined temperature is higher than the first predetermined temperature by 6° C. at highest.
Claim 4
Dependent Claim
44 words
An incubator as defined in claim 1 in which the incubator cell member includes an outer surface, and wherein said second heating means heats the incubator cell member by way of a metal member disposed on the outer surface of the incubator cell member.
