Soil Sampling Ring Kit – Model A53

The Soil Sampling Ring Kit Model A53 is a high quality undisturbed soil sampling set designed for collecting soil samples in seamless stainless steel rings (Ø 53 mm) up to a depth of 2 metres in soft soils.

It enables reproducible laboratory quality samples with exactly known volume and diameter — critical for soil physics tests such as bulk density, porosity, soil water air relationships and other physical property determinations.
The set is intended for use on the surface, in auger holes or profile pits, above as well as under groundwater level (in soft soils) as long as rocks do not interfere.

Key Feature/Highlight

• • Undisturbed soil sampling with rings of known fixed volume ensures highly consistent laboratory results.
• • Diameter Ø 53 mm sample rings, length ~51 mm, corresponding to about 100 cc volume.
• • Suitable up to depth of ~2 metres in soft soils for vertical sampling.
• • Made with seamless stainless steel tubes, smooth interior and exterior to minimise friction.
• • Open ring holder version (for soft soils) allows quick ring exchange and efficient sampling.
• • Supplied in a carrying case with 24 numbered rings + lids, cleaning brush and accessories for field operations.

Technical Specifications

Application / Usage Areas

• • Soil physical property research: bulk density, porosity, soil water air relationships, pore distribution.
• • Agronomy and soil science labs: determination of moisture content at various tension levels, building pF curves.
• • Environmental and geotechnical investigations: sampling above and below groundwater level in soft soils for laboratory testing.
• • Quality control and research in soil structure, infiltration and stability where undisturbed cores are required.

Benifits /User Advantages

• • Ensures high repeatability and quality of undisturbed soil samples due to precise ring dimensions and seamless design.
• • Enables vertical sampling up to 2 metres, capturing full profile data in soft soils—useful for deeper investigations.
• • Minimised sample disturbance ensures more reliable laboratory testing for density, permeability, porosity, etc.
• • Comprehensive kit with field ready components (rings, holder, case, accessories) reduces field logistics and setup time.
• • Trusted manufacturer and precision construction support long term use and reliability.

Best Practice & Considerations

• • Ensure the sampling location is free of large rocks or obstructions beyond the kit’s design—rocks may disturb ring insertion.
• • Use the ring holder correctly (open type for A53 kit) and ensure the ring is fully inserted and held firmly during sampling to avoid sample loss.
• • After taking core samples, label each ring clearly and transport carefully to the lab to preserve undisturbed structure.
• • Clean and dry rings thoroughly after use — corrosion or residue may affect precision over time.
• • Remember: this kit is for soft soils (model A53). For harder soils or hammering situations, consider other models (e.g., C53, E53) with more robust ring holders.
• • Ensure proper correspondence between sample volume and test protocols in lab (e.g., 100 cc rings) for calculations of density/permeability.
