The multi-function sample holder is a device used to provide flexibility and high efficiency in various scientific research and industrial applications. It is commonly used in X-ray diffraction (XRD) analysis and electron microscopy, and is an accessory of X-ray diffractometers (XRD accessory). As an accessory of X-ray diffractometers (XRD accessory) usually equipped with adjustable countertops to accommodate samples of different sizes and shapes.The multi-function sample holder is one of the indispensable tools in modern laboratories and research institutions. It greatly promotes the development of scientific research and industrial applications by providing a flexible, efficient, and accurate sample processing and analysis platform. Whether in the fields of materials science, biomedicine, or electronics industry, multifunction sample holder play an important role in helping researchers and engineers better understand and improve their research subjects.
