Abstract
A liquid sampling device which may be lowered by a cord into a pool of fluid to sample the fluid at a particular depth includes a housing for holding a sample bottle to be filled with fluid. A remotely operable valve means prevents the sample bottle from being filled until the cord is abruptly jerked. After the bottle is filled, an automatically closing valve means seals the bottle and prevents contamination of the fluid sample by fluid at other levels as the sampling device is raised from the pool of fluid.
