The in-situ cell should be optimized and operated, and an extension of the cell is planned. At the moment chemical reactions in fluid media can be studied and reaction parameters like temperature, pressure, pH-value, redox potential and conductivity can be simultaneously controlled and the concentration of the species in solution can be identified and determined. Simultaneous in-situ X-ray scattering experiments should be realized by modifying the cell. It is planned to attach a measurement cell to the crystallization cell and to optimize the pump types allowing to perform such experiments. Up to now the tested pumps were not suitable to fully explore the potential of the crystallization cell. Hence different external measurements cells attached to the main cell should be developed and also new pumping concepts. During the first period several working groups of the SPP used the cell and in the second period other project partners should use the cell for investigations of chemical reactions. Moreover the partners can modify the cell by further extensions according to their needs.

原位电池应进行优化和操作，并计划扩展电池。目前可以研究流体介质中的化学反应，同时控制温度、压力、ph值、氧化还原电位和电导率等反应参数，识别和测定溶液中物质的浓度。同时原位x射线散射实验需要通过改造电池来实现。计划将测量单元连接到结晶单元并优化泵类型以允许进行此类实验。到目前为止，所测试的泵还不适合充分挖掘结晶电池的潜力。因此，应该开发不同的附加在主电池上的外部测量电池和新的泵送概念。在第一阶段，SPP的几个工作组使用了该电池，在第二阶段，其他项目伙伴应使用该电池进行化学反应的研究。此外，合作伙伴可以根据他们的需要通过进一步扩展来修改单元。
