SKE品牌的AutoFee是一個由pH監(jiān)測驅(qū)動的自動培養(yǎng)基交換系統(tǒng)。這款產(chǎn)品的設(shè)計理念是適用于任何生物反應(yīng)器或培養(yǎng)器。
AutoFeed可*小化人力操作,降低手工操作培養(yǎng)基交換引起的污染風險,進而保持培養(yǎng)環(huán)境的穩(wěn)態(tài)。
背景
體外細胞培養(yǎng)的pH監(jiān)測可提供細胞代謝過程的有用信息,對于確保組織工程過程的再現(xiàn)性和標準化起著重要作用,進而將研究級別的生產(chǎn)模型轉(zhuǎn)化成臨床應(yīng)用級別的制造規(guī)模。
當培養(yǎng)基在周期性的批次培養(yǎng)中交換時,pH,代謝產(chǎn)物濃度和信號分子的突變會嚴重阻礙培養(yǎng)系統(tǒng)的恒定控制。

AutoFeed is an automatic medium exchanger driven by pH monitoring, designed to easy fit any bioreactor or culture chamber. AutoFeed minimises labour intensive operator handling, reduces contamination risks during manual medium exchange processes and preserves the homeostasis of culture milieu.
For the successful implementation of stem cell culture in bioreactor systems several critical parameters need to be addressed. These include physicochemical variables such as pH, dissolved oxygen, temperature and biochemical input, including the levels of key nutrients and metabolites, or growth factors: Autofeed provide fresh medium through a medium recirculator and mantain a suitable level of key nutrients in the culture. Like others SKE products, the system is highly configurable, customizable and adaptable for almost every bioreactor.
