Before the new purchase of scientific research equipment procurement, you can check the following steps. First, submit the scientific research results to the checking and reviewing system. The system will conduct a preliminary screening of the submitted literature to exclude the parts with high similarity to the existing literature. For the literature that passes the preliminary screening, the system will make a detailed comparison and generate a weight check report. Researchers can make final comments based on the checking report, avoiding the duplication of instrument and equipment purchases from the source and improving the utilization efficiency. Such a checking process can ensure that the acquisition of scientific research equipment meets the actual needs and avoids the waste of resources.
