Sample Tube Extruder 38mm Diameter Manufacturer,Supplier and Exporter in India
Product Code : TVT-STE-10590
The Sample Tube Extruder (38 mm Diameter) is a hydraulic jack-based accessory used to remove undisturbed soil samples cleanly from standard 38 mm diameter sample tubes without disturbing the recovered material.
How It Works
A vertically mounted, lever-action hydraulic jack extends the extruder body to form a chamber sized to accommodate a standard 38 mm diameter sample tube; operating the jack advances a piston through the tube, pushing the undisturbed soil sample out steadily for sub-sampling, further testing, or transfer to specimen containers.

Applications
This extruder supports the handling of undisturbed samples recovered by thin-walled tube sampling per ASTM D1587: Standard Practice for Thin-Walled Tube Sampling of Soils and the general subsurface investigation practice of IS 1892: Code of Practice for Subsurface Investigation for Foundations, giving laboratory staff a controlled way to extract 38 mm diameter samples for triaxial, unconfined compression or index testing without disturbing the soil structure.

Frequently Asked Questions
What tube size does this extruder handle?
It is sized for standard 38 mm diameter sample tubes.
Why is a hydraulic jack used rather than manual pushing?
The lever-action hydraulic jack gives a smooth, controlled push that minimises disturbance to the undisturbed soil sample compared with manual extraction.
What happens to the extruded sample?
Once extruded, the undisturbed soil sample is typically sub-sampled or trimmed for further tests such as triaxial, unconfined compression or index testing.
