High- and Low-Pressure Columns

For biopharmaceuticals separation, we can also find glass or plastic material (cross-linked polymers like acrylic). Table 4.3 gives typical dimensions and operating pressures of glass and large-scale acrylic columns for low-pressure bioseparations or intermediate purifications that are characterized by a height to diameter ratio 1. 

Construction materials for columns can be chosen according to several attributes Table 4.4 shows an example of selecting criteria for the most common materials
