Cerumen, also known as ear wax, is a waxy substance secreted in the ear canal that protects and lubricates the ear canal and assists in cleaning by trapping dirt and dead skin cells. Pickering Laboratories offers artificial ear wax that can be used for testing of hearing aids, ear buds and other electronic devices meant to be used in the ears.

Artificial Lysosomal Fluid (ALF) and Gamble’s solution were used to simulate different interstitial conditions in the lung. ALF is analogous to the fluid with which inhaled particles would come into contact after phagocytosis by alveolar and interstitial macrophages in the lung. Gamble’s solution represents the interstitial fluid deep within the lung. Citrate was used instead of proteins to avoid foaming and acetate instead of organic acids. Gamble’s solution has a pH of 7.4, whereas ALF has a pH of 4.5 and has a much higher organic content than Gamble’s solution.
