Lost Tips

Lost or expendable tips are widely used by the geotechnical industry for numerous reasons, such as the placing of piezometer standpipes for groundwater profiling, soil gas, grouting, etc.

The tips are either made of cast iron or machined steel. They remain in the soil upon retraction of the tubes leaving thus an open cavity for downhole applications.

The tips are typically designed for use in a variety of soil conditions. The dual O-rings provide a strong holding force to maintain the tip within the holder even when penetrating soft formations. To be used in combination with a holder.
