Humboldt Soil Grinder for Laboratory Soil Sample Processing and Pulverization (HU4199-000)

Prepares soil samples to proper particle size for accurate, repeatable test results

This laboratory soil sample grinder is engineered to deliver consistent particle size reduction, a critical step in soil analysis protocols used in agronomy, environmental science, and geotechnical testing. Research in soil mechanics and agricultural testing highlights the importance of uniform sample preparation to reduce variability in moisture content, nutrient analysis, and contaminant screening (e.g., ASTM and ISO guidelines for soil sample preparation). Customer reviews and industry articles note the unit’s ability to quickly produce homogenous ground samples, with many laboratories reporting improvements in test repeatability and workflow efficiency. This model is commonly used in university research labs, commercial testing facilities, and environmental consulting firms, with users praising its robust construction, rapid processing time, and reliable performance in daily sample preparation.

Efficient Grinding Performance

Prepares soil samples rapidly and consistently to proper particle size for accurate and repeatable test results — an essential attribute for reliable analysis in laboratories.

• Grinds one-pint sample in 15 seconds.
• Stainless steel construction.
• Includes a No. 10 perforated stainless plate.

Durable, Laboratory‑Grade Build

Constructed from high‑grade stainless steel, this soil sample grinder resists corrosion and wear, making it well suited for frequent use in demanding laboratory environments where precision and durability matter.

Rapid Throughput

The ability to grind a standard one‑pint soil sample in approximately 15 seconds helps laboratories improve turnaround times for routine soil testing, including particle size distribution, nutrient profiling, and contaminant screening.

To complement the functionality of the Laboratory Soil Grinder — a stainless‑steel sample prep mill that rapidly reduces caked soil to designated particle size for accurate, repeatable geotechnical and materials testing ([turn0search1](#)) — consider additional instruments that support soil and materials characterization workflows. The Soil Moisture Meters deliver quick in‑situ gravimetric or volumetric water content measurement to inform moisture conditioning prior to grinding and analysis.

For precise mass determination before and after sample preparation, the EX423 Explorer Precision Balance provides robust high‑capacity weighing with dependable repeatability tailored to QA/QC workflows. Additionally, the Soil Sampling Tube enables consistent core retrieval from field sites, ensuring representative samples for processing and subsequent laboratory testing.

Q&A

What types of soil can be processed with this grinder?

This grinder is designed for typical mineral and organic soil types encountered in agricultural, environmental, and geotechnical testing. Extremely rocky or highly compacted materials may require preliminary crushing.

Is the perforated plate replaceable?

Yes, the included No. 10 perforated stainless plate can be replaced or swapped with compatible plates to adjust final particle size according to testing requirements.

How does uniform particle size improve test results?

Consistent particle size increases the reliability of analytical results by reducing variability due to sample heterogeneity, which is critical in standardized soil tests such as nutrient assays, hydrometer analysis, and contaminant measurements.
