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.

应对现场单元进行优化和操作，并计划扩大单元。此时，可以研究流体介质中的化学反应，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，并可以识别和测定溶液中物种的浓度。同时进行原位X射线散射实验应通过改装小室来实现。计划在结晶池上安装一个测量池，并优化泵的类型，以便进行这样的实验。到目前为止，所测试的泵并不适合充分挖掘结晶细胞的潜力。因此，应开发连接到主电池的不同外部测量电池，并开发新的泵送概念。在第一阶段，战略规划方案的几个工作组使用该单元，在第二阶段，其他项目伙伴应使用该单元进行化学反应调查。此外，合作伙伴还可以根据自己的需要对单元进行进一步扩展。
