Samplers

There are a number of myths relating to the CPT (cone penetration test). Perhaps the biggest myth is that CPT rigs cannot obtain sample. This is not true, the CPT platform can be used to deploy: high quality Bergemann (Delft) piston samples in soft clays fixed piston MOSTAP stockinet samples thin wall Shelby samples �disturbed� push windowless samples
Soil samplers
MOSTAP >>	Continuous undisturbed soil samples at discrete depths. Available diameters: 35mm and 65mm. Available sample lengths: 1m, 1.5m and 2m.
Shelby sampler >>	Continuous undisturbed soil samples at discrete depths. Available diameters: 35mm and 65mm. Available sample lengths: 1m, 1.5m and 2m.
Delft continuous soil sampler >>	Continuous samples. Diameter: 29mm or 66mm.
Water samplers
Delft groundwater sampler >>	A multi-level groundwater sampling probe. With this probe groundwater samples can be retrieved from multiple sampling depths during one and the same CPT operation.
WASTAP >>	The WASTAP provides 2 methods for water sampling; one in which the sample is pumped up to the surface, another in which the sample is collected in a container in the sampler.
