2.1 Niskin Bottle 

5L plastic Niskin bottles are used for sea water sampling. The bottles are designed for water sampling at various water column levels. Niskin bottle is submerged open-ended. The bottles are closed at the given levels with the help of sliding weights run on cable. 

2.2 Go Flo Bottle 

10L plastic Go Flo bottles are used for sea water sampling. The bottles are designed for water sampling at various water column levels. Go Flo bottle is submerged closed (to prevent surface film getting inside) and opened by a hydrostat at a depth of about 8-10 metres. The bottles are closed at the given levels with the help of sliding weights run on cable.

2.7 Washing Sieves with 1mm Mesh

Special washing sieves with 1mm mesh are used for washing of soil collected by grab sampler.

2.8 GR-91 Drag Grab Sampler 

GR-91 drag grab sampler is designed for sampling of loose silt and fluvial bottom sediments with structural rupture from the bottom of rivers and channels with a depth of up to 3 metres and water current speed of up to 2 m/s and lakes and water reservoirs with a depth of up to 4 metres. The min. bucket capacity is 300 cubic centimetres.

2.9 Chemical Containers and Samplers 

Bottom sediment samples for chemical analysis are taken from the grab sampler with the help of special cylindrical samplers. Samples are transferred from samplers into special pre-cleaned plastic and glass Nalgene chemical containers.
