A simple, pneumatically operated multilevel sampler easily constructed of cheap, readily available material is described. Syringes of different volumes can be attached swiftly and interchanged at appropriate intervals. External parts are immovable during filling, thus reducing disruption of microstratifications and keeping contamination of samples to an absolute minimum. The sampler can be used for dissolved gas analyses and multiple bioassay investigations.
