Fluoroelastomers containing copolymerized units of vinylidene fluoride, perfluoro ether, 2-hydropentafluoropropene, and, optionally, tetrafluoroethylene, and having an iodine atom present at some polymer chain ends, exhibit excellent low temperature properties and processability when dual cured with both polyhydroxy compounds and organic peroxides. Specifically, under the present invention, base characteristics are designated for a new user profile. When the sharps within the container have reached a certain level, a coagulant is poured into the container. If it is determined that the bus approval signal has been generated due to the bus blank period, the bus blank determiner controls the count initialization value setting unit, the bus request signal generation unit, and the refresh signal generator. The pump drives flow of the sample from the reservoir, through the liquid flow path, and back to the reservoir.
