Double Gate Variable Depth Sampler
The Double Gate Variable Depth Sampler is designed to permit collection of undisturbed core samples of liquids, sludge, or silt. These samples can be taken from specific depths within the test material without mixing the material during deployment of the sampler. Additionally, it allows retrieval of the sample without any loss of the sample and seals the sample to eliminate cross contamination during withdrawal of the sampler from the materials under analysis.

Market Assessment
The most promising application for this sampler would appear to be in the waste-sludge and sediment sampling markets, but has potential applications in environmental characterization and monitoring, oil refining, and brewing

Patent Status
A U.S. patent application has been filed on this invention.

Stage of Development
This device has been prototyped and has been used successfully in sampling operations at SRS.
