Do inconsistent soil dispersion and variable mixing speeds compromise the accuracy of your hydrometer analysis results? In geotechnical and particle size testing, proper sample preparation is the foundation of reliable data. The Soil Dispersion Mixer for Hydrometer Analysis is specifically engineered to meet the rigorous requirements of ASTM and AASHTO test methods. This robust instrument, featuring a powerful motor and specialized baffled dispersion cup, ensures complete and repeatable deflocculation of soil samples, giving you confidence in your particle size distribution measurements.

Why Choose This Soil Dispersion Mixer? Solving Inconsistent Sample Prep & Compliance Challenges

Achieve reliable, standards-compliant results with features that directly address common geotechnical laboratory pain points.

• Ensure Test Method Compliance Every Time: Hydrometer analysis requires specific mixing energy to properly disperse soil without damaging particles. This ASTM-compliant soil dispersion mixer is designed to meet the exact specifications of ASTM and AASHTO standards. The combination of the high-speed dispersion mixer's three speed settings (13,000, 16,000, and 18,000 RPM) and the stainless steel baffled dispersion cup guarantees that your sample preparation protocol is always in line with industry requirements.

• Achieve Complete and Uniform Soil Dispersion: Partial dispersion leads to inaccurate particle size curves. The soil dispersion mixer's powerful 1/3 hp motor drives a specialized blade within the cup, which features four integral baffles. This creates the intense, uniform shearing action necessary to fully separate soil particles into their primary sizes, ensuring that your hydrometer readings reflect the true gradation of the sample.

• Built for the Demands of a Busy Lab: Geotechnical testing can be tough on equipment. This lab disperser for particle size analysis is built with a heavy die-cast aluminum housing and a reinforced spindle, providing the durability needed for continuous use in commercial, research, or educational laboratory environments. The included manual pulse switch gives you additional control for customized mixing protocols when needed.
