Pickering Laboratories Inc Artificial Eccrine Perspiration , Stabilized, each (5 mL/bottle)

Perspiration is on everything we touch with our fingers or that comes into contact with our bodies. Sweat can react with materials and trigger allergies, or it can shorten product service life via corrosion or discoloration. Natural human perspiration has a complex composition that depends on the type of sweat gland, the person’s metabolism and hydration level. Pickering Laboratories’ human mimic artificial perspiration solutions are formulated based on published data for human sweat and provide the closest match to the “real thing” available on the market. These solutions are perfect for testing a variety of consumer products and medical devices as well as for forensics applications. Artificial Eccrine Perspiration is a ready to-use human eccrine sweat solution. It consists of nineteen amino acids, the seven most abundant minerals, and the four most abundant metabolites at a pH of 4.5.

Pickering Laboratories Inc Artificial Saliva, ASTM E2720-16 and ASTM E2721-16 with mucin, Custom pH, Stabilized, each (200 mL/bottle).

This artificial saliva formulation has a mineral composition and pH close to human saliva. Mucin is added to increase the viscosity and lubricating ability of the artificial saliva. This solution can be used for dental, drug delivery or pharmaceutical studies. The stabilized solution is pre-mixed and has a preservative added to prevent bacterial growth; it is stored at room temperature. Amylase is the main enzyme in human saliva and is needed for starch digestion. As some applications require studying the effect of enzymes in saliva, Pickering Laboratories offers an easy way to add biological activity to your chosen artificial saliva product. Once added to the 200 mL bottle of artificial saliva, our Amylase product will provide 80 U/mL of enzyme activity. Provided at a pH level of your choosing
