細胞能量代謝分析儀

Resipher細胞能量代謝分析系統(tǒng)是在標準孔板中直接精確地測試樣本的耗氧量。其采用了離分辨率動態(tài)光學氧氣傳感器，對細胞無干擾。儀器設計小巧，緊湊，操作簡易。帶樣本的孔板放置在測試環(huán)境中后，直接把帶探針的蓋子直接插入即可，無需再轉(zhuǎn)移樣本，消除了環(huán)境改變的影響。

Resipher細胞能量代謝分析系統(tǒng)軟件為網(wǎng)格化設計，即對每個孔板內(nèi)的樣本—對應分析，實現(xiàn)對每個樣本的監(jiān)測，快速、可視化地讀取和分析數(shù)據(jù)?？赏ㄟ^電腦或移動終端，遠程查看實時實驗數(shù)據(jù)，獲悉細胞狀態(tài)。

Resipher采用高分辨率光學氧氣傳感器，測定細胞培養(yǎng)中的耗氧量及氧環(huán)境的變化。

Resipher是—款手持便攜式設備，放置 96 孔板上，置千培養(yǎng)箱中，對孔板內(nèi)的樣品進行測試。Resipher主控制盒與無菌帶光纖探針的蓋子連接，蓋子上的探針直插入培養(yǎng)基中內(nèi)。微型探針直徑 500 µm，對細胞織無損傷。

細胞耗氧量是通過培養(yǎng)基中的氧濃度的梯度變化來直觀反應的。通過動態(tài)掃描，讀取培養(yǎng)基中的氧濃度的梯度變化，再通過信號處理和計算得出實時的細胞耗氧量值。

數(shù)據(jù)記錄儀放置在培養(yǎng)箱外，可擴展連8個主控制盒。軟件為網(wǎng)格化設計即 對每個孔板內(nèi)的樣本一一對應分析，實現(xiàn)對每個樣本的監(jiān)測，可視化快速分析。

除了耗氧量外，也可以接入外接信號，獲取氧氣濃度、培養(yǎng)箱溫度、相對濕度、大氣壓、設備運行狀態(tài)和其它環(huán)境因素等參數(shù)。
