Protein secondary structure can be determined by the Circular Dichromism where as XRD can be used for the Tertiary structure prediction of the protein. Freeze drying is an unit operation for the concentration increase in a solution of limited solute. Ultra centrifugation is the unit operation for sedimentation. ​

⚈ The Diaphragm Pressure Gage uses the elastic deformation of a diaphragm (i.e. membrane) instead of a liquid level to measure the difference between an unknown pressure and a reference pressure. ​​
⚈ ​In an antifoam system; if the foam contacts a rubber sheathed electrode, an electric unit actuates a solenoid valve to allow the passage of a sterile antifoam agent into the fermentor.
⚈ A final widely used method for the determination of cell number is a turbidometric measurement or light scattering. This technique depends on the fact that as the number of cells in a solution increases, the solution becomes increasingly turbid (cloudy). The solution looks turbid because light passing through it is scattered by the microorganisms present and the turbidity is proportional to the number of microorganisms in the solution. The turbidity of a culture can be measured using a photometer or a spectrophotometer. Photometers, such as the Klett-Summerson device, use a red, green or blue filter providing a broad spectrum of light. ​​
⚈ A rotameter is a device that measures the flow rate of liquid or gas in a closed tube.
