Abstract
A no purge sampler for collecting fluid samples includes a flexible tube having a sealed first end and a second end, the tube defining an interior cavity, a check valve disposed at the second end of the tube, and at least one aperture above the check valve. To collect fluid samples, the no purge sampler is lowered into the fluid to be sampled. The at least one aperture streamlines the tube as it is lowered into the fluid reducing drag-down and mixing. Once the sampler reaches the desired depth, the sampler is pulled upwards allowing fluid to enter the interior cavity. The sampler is then pulled out of the fluid without losing any of the fluid in the interior cavity of the tube or contaminating the sample with any extraneous fluid.
