No grinder can beat the speed of a Vibratory Disc Mill when it comes to preparing samples for spectral analyses. RETSCH have now redesigned their RS 200 model for even more convenient operation and handling of the grinding sets.

An ergonomic carry handle facilitates carriage of the heavy grinding jar which is slid on a rail into the optimum position inside the mill. The new clamping device allows for safe clamping of the jar with less force, an additional sensor checks its correct position.

RETSCH’s RS 200 with its powerful stabilized plane drive achieves grind sizes between 20 and 100 microns within seconds and with excellent reproducibility. Grinding sets are available in a variety of sizes and materials. A set of sensors will recognize jars of tungsten or agate and automatically sets the maximum permissible speed, ensuring optimum results while protecting the material.


Benefits at a glance
• Very short grinding times, typically in the range of 60 to 180 seconds to achieve the fineness necessary for XRF and other spectral analyses (around 100 microns)
• Easy handling of the grinding set due to new ergonomic design and new carry handle
• New quick-action grinding set clamping system for convenient and safe tightening
• Powerful Stabilized-Plane-Drive
• Variable speed 700 - 1,500 min-1
• Protection of the grinding set (reduced speed of 1,200 and 700 rpm respectively) due to automatic tungsten carbide and agate detection
• Easy 1-button operation with colored graphics display and optimized menu structure, 10 SOPs storable

Particle CharacterizationParticle characterization instruments are used to determine particle size distribution, shape, surface area, zeta potential, density and porosity of particles and materials. Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters. Find the best particle characterization instruments in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Homogenizers and BlendersHomogenizers and blenders are used to homogenize various types of material, including tissue, cells, plants, food, soil, biological and chemical samples for subsequent analysis. Lab equipment for sample homogenization includes handheld and benchtop homogenizers, bead mill, ultrasonic and multiple sample homogenizers, high shear homogenizers and blenders. Homogenizer bead and probe multipacks are available to avoid cross contamination of samples, as well as cooling systems for homogenizing temperature-sensitive samples. Homogenizers are often used in the first step of extraction of DNA, RNA and proteins from tissue and cell samples.
