Peat & Sediment Sampling - Samplers
Multisampler
The Multisampler comprises a transparent acrylic tube with a piston arrangement. It captures samples within the tube and they can be visually inspected. The Multisampler can only be used for the top metre of sediment. The cutting head can easily be exchanged with one which contains a check valve to prevent the sample from falling out. The Multisampler can be easily disassembled and apart from the acrylic tube (which can be capped for transport), all remaining parts are stainless steel for easy decontamination.
Van Veen Grab
Semi disturbed sampling of river and lake beds, large sumps. The Van Veen Grabs take a surface sample only. They are suspended by wire so can easily be deployed. Sizes range from 0.5 to 12 litres capacity
Ekman Grab
This stainless steel sampler is intended for use in soft sediment that is free from debris and plant growth. Samples can be taken from top layers and spring loaded jaws prevent loss of material as long as there are no small stones or stalks to prevent closure. A sample can be viewed through an opening in the top before the sample is retrieved. The 3.5 litre sampler comes complete with synthetic line to reach a depth of 30 m.
Beeker Sampler
This is the most sophisticated sediment sampler. Completely undisturbed samples are captured in an acrylic sampling tube. An inflatable bladder resides within the cutting shoe to ensure perfect sample retention. The Beeker sampler can be inserted in a closed position to the required sampling horizon then opened. The Beeker sampler is perfect for a visual assessment of the often critical water/sediment interface. Sub-samples can easily be obtained by a laboratory partitioning system.
Flap Gouge Auger
The Flap Gouge Auger is for sampling in dry or wet material to a depth of 2 metres. The slender construction allows for ease of penetration in sludges, sediments, powder, grain, granulates (< 3mm) and pastes. This makes it ideal for taking samples in drums, tanks and bags.
