Density control of polymeric gels for reliable blood component separation and diagnostics
Blood testing is essential for detecting, diagnosing, and treating diseases. Accurate results depend on effective blood component separation, typically done by centrifuging samples in tubes with a polymer or gel. Controlling the polymer's density ensures reliable separation of plasma from blood cells, supporting consistent and accurate test results.
This report shows that DMA benchtop density meters are an ideal solution for accurately determining the density of polymeric gels used in serum-separating tubes. They provide highly repeatable results regardless of the operator, enabling improved product quality. Each measurement, including cleaning, is completed in under 10 minutes per sample and requires only a small volume.
In the pharmaceutical industry, where accuracy is essential, verifying the instrument's status by measuring a certified reference material (CRM) according to its specifications is recommended. This verification can be reliably performed with DMA benchtop density meters.
