Abstract:
In this paper we discuss adaptations to the BioLogic stopped-flow module (SFM)-400 stop-flow rapid mixing apparatus to enhance reliability for use on a small angle X-ray scattering (SAXS) beamline. Issues with the standard capillary holders are discussed and a 3D printed alternative is presented. The reliability of the new design against leakage is reported. Alternate resins with enhanced solvent tolerance are trialled and discussed.
