Abstract
An apparatus is provided for obtaining fluid samples with the apparatus having a tubular body with a top and a bottom. A spring operated plunger shaft extends axially from the top to the bottom of the tubular body. A sample volume cap is attached to an end of the spring operated plunger shaft. A plunger is attached to the spring operated plunger shaft. A fusible link is used to maintain the spring operated plunger shaft in a first position. Upon activation of the fusible link, axial motion of the spring operated plunger shaft draws fluid into the tubular body trapping the fluid between the plunger and the sample volume cap inside the tubular body.
