Description
なお、上述した本実施の形態において、例えば、図7に示すように、分析用バッファタンク30の貯留空間31に貯留された培地を、循環ライン70によって循環させるようにしてもよい。図7に示す形態においては、培地フィルター11とアウトレット開閉弁12との間に第1循環切替弁71が設けられ、第2アウトレットポンプ17とアウトレット切替弁18との間に、第2循環切替弁72が設けられている。第1循環切替弁71と第2循環切替弁72とを、循環ライン70が連結している。なお、図7においては、図面を明瞭にするために、アウトレット洗浄液供給源20は省略している。
また、上述した本実施の形態においては、本発明によるバッファタンクを、図1に示す分析用バッファタンク30に適用した例について説明した。しかしながら、このことに限られることはなく、本発明によるバッファタンクを、図1に示す新液用バッファタンク6に適用してもよい。この場合、インレットヒータ5により加熱された培地が新液用バッファタンク6内で均質化されるまでの時間を短縮することができる。このため、培養容器100の通路104内に供給された培地を均質化させることができ、培養される細胞の品質を向上させることができる。
