A peristaltic device for solution sample measurement applied in small‐angle X‐ray scattering at synchrotron radiation was developed . The radiation damage can be efficiently restrained by using this device w hose features are good sealing ,easy opera‐tion ,low background scattering ,small sample consumption ,and the sample tempera‐ture can be controlled for in‐situ measurement .The sample volume and peristaltic rate of the device were calibrated ,and the validity of reducing radiation damage was also verified .The results indicate that this peristaltic device is an effective tool for precise X‐ray scattering measurements with high control accuracy .
