title: Testing the effects of fluids on rat skin using disposable polypropylene chambers.
abstract: Inexpensive, disposable polypropylene chambers for testing fluids on rat skin were made by removing the wings from polypropylene wing nuts and by cutting into the top of each nut a seat for an O-ring. Polypropylene screws with black heads were fabricated as seals for the chambers. After attachment to the backs of rats, these chambers provided a satisfactory  means of keeping fluid in contact with the skin for 3 days.
