      Application Uses    
                  This is an innovative vertical water sampler which can collect water from different depth without any cross contamination from other layer.
      Salient Technical Features    
                  - DDWS is the improved version of Niskin sampler, which is used for vertical water sampling from long past throughout the world.
 - DDWS can dip to the desired depth and from boat with a rope the lid can be open for filling of water.
 - Water filling can be checked from boat by observing the bubble which comes to the surface of water.
 - After filling of water, bubble formation stops and it can be assumed that the sampler is filled with water. After that the lid can be closed from boat by using another rope.
 - Such monitoring process is not available in case of Niskin sampler which go to the desired depth in open condition, which increase the chance of cross contamination from other layer. Further Niskin sampler work based on messenger and therefore in the area where undercurrent is very strong, false operation is very common in case of Niskin sampler.

      Scale of Development:    
                  The product has already been developed. Used extensively during environmental sampling of CSMCRI for last 2 years successfully.
      Business scope & opportunity    
                  We are in contact with companies who are involved in coastal/marine sampling.
      Environment Considerations    
                  This instrument is made up of steel or other metal which are heavy and less chance of rusting. During operation no waste products are generated.
