RPMI 1640 culture medium was chosen to simulate body fluids, and after exposure to 0.085 approximately 0.092 T static magnetic fields (SMF), surface tension, pH, dissolved oxygen, and UV-visible spectrum were measured. Compared with the control group in the normal geomagnetic field, the pH value increased about 0.14 units, dissolved oxygen increased about 14%, and the UV-visible spectra were different in peak intensity but without a shift in the peak. Surface tension showed no significant difference in the two groups. This data suggests that SMF can change some of the physical and chemical properties of RPM1 1640 solution, and may contribute to understanding biological effects of SMF.
选择RPMI 1640培养基来模拟体液，在暴露于约0.085至0.092 T的静磁场（SMF）后，测量表面张力、pH值、溶解氧和紫外可见光谱。与正常地磁场中的对照组相比，pH值增加了约0.14个单位，溶解氧增加了约14%，紫外可见光谱在峰值强度上有所不同，但峰值没有偏移。两组的表面张力没有显著差异。这些数据表明，静磁场可以改变RPMI 1640溶液的一些物理和化学性质，并可能有助于理解静磁场的生物学效应。
