A set of equipment has been designed to take water samples by aspiration at varying depths in shallow ecosystems. The depths sampled can be freely selected within a range of accuracy of 1 cm. The equipment is portable and can be handled from a boat or from the shore, at points up to 20 m away from the sampling location. A study was made of the accuracy of temperature and dissolved gas content of samples obtained using this device. With respect to the gas analysis, there was no serious loss of gas from the samples as long as they aspirated under a reduced pressure
