Abstract
A sample tank for receiving and storing sampled connate fluid from a subterranean geological formation. The sample tank includes a piston coaxially disposed within the tank. The piston can be disposed close to the end of the tank where the sampled fluid is introduced into the tank and urged along the length of the tank as sampled fluid is added to the tank. The piston includes an agitator for mixing the fluid and keeping particulates suspended within the fluid. The agitator includes a magnetic member, and is rotated by applying a varying electromagnetic field to the member.
