Abstract
Foam tester device, which is useful for testing the foaming of liquids at elevated temperatures, has an insulated cabinet containing a temperature-regulatable volume; a heater capable of heating a gas for the volume; a feature to circulate heated gas in the volume; an access system such that sample container(s), each capable of holding a liquid sample, is(are) insertable into the volume so as to be heated; and a feature, for example, a window, to observe any sample(s) in the sample container(s) such that observation can be conducted from outside the cabinet. The foam tester is a gas, especially air, bath. Cooling may be provided by water or other liquid, for example, propylene glycol and water mixture, and/or by insert of a cooling device, for example, a cooling carosel or insert drawer in place of the foam tester sample carousel. Foam test operation is simplified, and the foam tester may be employed to operate sample testing cycles without removal of samples from the tester between tests.
