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.

应优化和操作现场电池，并计划扩大电池。目前，可以研究流体介质中的化学反应，并且可以同时控制温度、压力、pH值、氧化还原电位和电导率等反应参数，并且可以识别和确定溶液中物质的浓度。通过对样品池的改造，可以实现现场X射线散射实验的同步进行。计划将测量单元连接到结晶单元，并优化允许执行此类实验的泵类型。到目前为止，所测试的泵不适合于充分开发结晶池的潜力。因此，应开发附接到主单元的不同外部测量单元以及新的泵送概念。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研究化学反应。此外，合作伙伴可以根据需要通过进一步扩展来修改单元。
