Principle of Differential Scanning Calorimetry (DSC) : Hitachi High …
DSC enables the measurements of the transition such as the glass transition, melting, and crystallization. Furthermore, the chemical reaction such as thermal curing, heat history, specific heat capacity, and purity analysis are also measurable. Recently, with the development of the highly-functional polymeric material, these thermal properties ...
DNA extraction
DNA extraction is a technique for isolating DNA from cell membranes, proteins, and other biological components from a sample using physical and/or chemical processes. Several parameters, such as tissue type and DNA integrity, must be considered when selecting a DNA extraction method.
Principles and Methods of Preparation of Platelet-Rich Plasma: A …
In addition, the potential degradation of biological compounds during prolonged storage means faster separation techniques are needed. Hence, to accelerate sedimentation, the effect of gravity is amplified using ''centrifugal force'' provided by a centrifuge and can be many thousand times the force of gravity.
