Abstract : The invention, a microbiological specimen sampler, is presented which provides for the sterile recovery of microorganisms such as bacteria, fungi and yeast from ocean depths in undamaged form. The sampler comprises two substantially identical chambers axially aligned and separated by a port block. Each chamber contains a free floating piston, the pistons being initially disposed in the same respective position in the chambers. One chamber is virtually filled with a snubbing fluid between the port block and its floating piston while the other chamber is initially pressurized with a gas. At a preselected position and depth a valve is opened which admits seawater into the sampler forcing one floating piston to drive snubbing fluid through the port block against the other floating piston which compresses the gas in its chamber as sample fluid is admitted into the first chamber.
