Acetone may be used rarely. These solvents are flammable. In small quantities, these solvents are mild irritants of the skin and respiratory passages. Contact of concentrated solutions with the eyes can cause corneal damage. Epoxies may be used to connect various parts of the apparatus.
Epoxies pose a threat of skin irritation and allergic reactions to skin contact and fumes.
The experiment calls for the use of wave-length shifters on the surface of the target cell. These chemicals will be applied in another laboratory. As they may flake, there is possible exposure. Contact or inhalation of these chemicals in small quantities is a minor hazard. These are in a notebook on top of the the chemical storage cabinet.
