また、脱気装置3と真空ポンプ6とは流路3cで接続されている。流路3cは、例えば吸気管で構成されている。純水供給装置1Aから脱気装置3に供給された純水は、真空ポンプの作動により、溶存酸素や気泡が脱気される。本実施形態では、脱気装置3で脱気された純水は、流路3bを介して反応槽(恒温槽)5に供給される。後述するように、脱気装置3と反応槽5とが循環経路を形成しており、脱気装置3にて脱気された純水が、当該循環経路に供給されてもよい。
図3(A)及び図3(B)に示すように、中空糸脱気モジュール20Aは、筒体211の軸線方向一端部211a(図2参照)を封止する第1封止部231Aと、筒体211の軸線方向他端部211b(図2参照)を封止する第2封止部232Aとを有している。そして中空糸膜220の長手方向一端部220aが第1封止部231Aに固定されており、中空糸膜220の長手方向他端部220bが第2封止部232Aに固定されている。すなわち、中空糸膜束22の長手方向一端部22aが第1封止部231Aに固定されており、長手方向他端部22bが第2封止部232Aに固定されている。
前記中空糸脱気モジュールにおいて、中空糸膜の内側に恒温水を供給するとともに中空糸膜の外側を減圧することで恒温水を脱気することができる。
図5(A)及び図5(B)に示すように、中空糸脱気モジュール20Bは、筒体211の軸線方向一端部211a(図4参照)を封止する第3封止部231Bと、筒体211の軸線方向他端部211b(図2参照)を封止する第4封止部232Bとを有している。そして中空糸膜220の長手方向一端部220aが第3封止部231Bに固定されており、中空糸膜220の長手方向他端部220bが第4封止部232Bに固定されている。すなわち、中空糸膜束22の長手方向一端部22aが第3封止部231Bに固定されており、長手方向他端部22bが第4封止部232Bに固定されている。
前記中空糸脱気モジュールにおいて、中空糸膜の外側に恒温水を供給するとともに中空糸膜の内側を減圧することで恒温水を脱気することができる。
図6に示すように、中空糸脱気モジュール20Cは、筐体210Cと、筐体210Cの内部空間S5に配置された中空糸膜220Cとを有する。筐体210Cは、長手方向Lが略水平となるように配置された筒体211Cと、筒体211Cの長手方向一端部211Caに取り付けられた蓋部212Cとを有している。
図7に示すように、化学分析装置2Bは、反応ディスク401、反応容器402、反応槽403及び循環用ポンプ306を備える。円形の反応ディスク401の円周上に取り付けられた反応容器402は、同じく円形の反応槽403に保持された液体に浸漬されている。反応槽403内の液体は、排出配管404と供給配管405との間に設置された循環用ポンプ306により常時循環されており、ヒータ307のオン/オフ制御により温度制御されている。排出配管404と供給配管405の間の循環用ポンプ306及びヒータ307を含む経路が、温水循環経路を構成している。これにより、反応容器402の内部に保持された反応液を反応に最適な温度(例えば37℃)に保っている。
図8に示すように、化学分析装置2Cは、反応ディスク501、反応容器502、反応槽503、給水タンク504及び給水用ポンプ506を備える。円形の反応ディスク501の円周上に取り付けられた反応容器502は、同じく円形の反応槽503に保持された恒温水に浸漬されている。反応槽503には、給水タンク504から恒温水が供給される。給水タンク504と反応槽503の間の流路上には、中空糸脱気モジュール20A又は20Bを有する脱気装置505が設けられており、給水用ポンプ506と給水用弁507によって恒温水の供給が制御されている。脱気装置505内に供給された恒温水中の溶存気体は、真空ポンプ508の作動により脱気されて、供給配管517から反応槽503に供給される。
図9に示すように、(生)化学分析部4Bは、検体容器601、検体分注機構602、反応容器603、試薬容器604及び試薬分注機構605を有していてもよい。(生)化学分析部4Aでは、例えば、検体容器601から検体分注機構602を介して反応容器603に送られた検体と、試薬容器604から試薬分注機構605を介して反応容器603に送られた試薬を、混合・攪拌することができる。反応容器603は、反応槽606に貯められた恒温水により、一定の温度に保たれる。反応槽606に恒温水を供給する流路上には、中空糸脱気モジュール20A又は20Bを有する不図示の脱気装置が設けられ、恒温水の供給が制御される。
