A printing plate module is disclosed. The resulting homogenous solution is incubated at a desired temperature and time to result in a desired product. Compared to the conventional prior art, the clamping part of the electrical connector according to the present invention can not only effectively clamp a chip module, but also provide shielding to obtain better signal transmission effect for the electrical connector. The plurality of denaturation graphs allows analysis of the effect of that variable on protein stability. The control unit controls the measuring electrode and the calibrating electrode such that the measuring potential and the calibrating potential are equal in a measuring phase, and differ from each other in a calibrating phase. The catalyst composition has an X-ray diffraction pattern in which the characteristic full width at half maximum does not exceed 2.
