Prosector
Generally, the risks to prosectors are low. Cadavers used for teaching purposes are embalmed before they are encountered by a prosector and students. Embalming fluid usually contains formaldehyde, phenol, Dettol, and glycerine which disinfect and kill pathogens within the cadaver. With exposure to embalming fluid, tissues and bodily fluids, such as blood, become fixed. Prosectors and students working with embalmed cadavers must always wear protective gloves, however this is more for protection against the harsh chemicals used in embalming such as formaldehyde and dettol which can cause moderate to severe skin irritation.
Climbing and falling film plate evaporator
Antibiotics, supplementary pills and drugs containing organic and inorganic compounds are evaporated to remove as much moisture as possible for crystallization. This is because in crystallized form, antibiotics and enzyme compounds will be well preserved and improved in stability. Moreover, exposure to high temperature will lead to decomposition of inorganic compounds. Although most pharmaceutical products are extremely sensitive in temperature, this type of evaporator is still practical to be used since several design of this evaporators are able to operate at low pressure since the boiling point of water is low as pressure decreases.
