SK-350 TII – Twin 400 ml Cups
This advanced planetary centrifugal mixer builds on the basic individual revolution and rotation speed control system by adding enhanced processing functions for more demanding materials. The unit allows the revolution speed and rotation speed to be set independently, giving users greater control over mixing, dispersion, and defoaming conditions. With the ability to process up to 700 g of material using two 400 mL containers weighing up to 350 g each, it is well suited for laboratory-scale development and material testing. In addition to its standard mixing and defoaming capabilities, the model includes high-speed mode for intensive processing and anti-separation mode, which helps suppress separation in materials with different specific gravities, such as powder-and-liquid mixtures.

TG 200 Fluid Bed Dryer
The fluid bed dryer TG 200 is used in quality control, sample preparation, and R&D departments. It permits the gentle drying of organic, inorganic, chemical, or pharmaceutical bulk materials without localized overheating. Suitable materials can be coarse, fine, crystalline, fibrous, or leafy. The powerful fan of the fluid bed dryer ensures optimal air throughput so that the products to be dried are loosened up and thoroughly mixed resulting in short drying times. With the interval operation, the fluidized bed is mixed even better. Temperature, drying time and air volume can be set digitally and adjusted continuously.
The TG 200 now offers an extended maximum time setting, increased from 99 minutes to 9 hours, with several intermediate steps. This enhancement allows users to initiate longer drying processes, including overnight operations, without any risk. Continuous drying remains an available option.

TM 300 Drum Mill
The TM 300 Drum Mill is utilized for preparing granules and powders through a grinding process conducted in either dry or wet conditions. This versatile grinder can function as either a Ball or a Rod Mill by employing the corresponding module. To ensure an efficient grinding process, it is essential to use a sufficient number of balls or rods. Depending on the sample material, a final fineness below 20 microns can be achieved.
The drum mill comprises a gear motor mounted on a robust steel frame, a set of separation grids, and a sample collector. The TM 300 is designed with a yoke and locking mechanism that facilitates easy access to the sample. Cleaning is made convenient by a quick-release locking mechanism, allowing effortless removal of the drum cover.
The TM 300 accepts sample volumes up to 9 l and is therefore also suited for upscaling processes.

TM 500 Drum Mill
The Drum Mill TM 500 is a laboratory ball mill designed to grind large sample volumes up to 35 l. It accepts initial feed sizes of up to 20 mm and can achieve grind sizes down to 15 µm by friction and impact.
Hard, brittle or fibrous samples are pulverized in the 150 l drum filled with 80 kg grinding balls. The variable speed of 10 to 50 rpm, different grinding ball sizes and the possibility of long-term grindings of up to 100 h ensure perfect adaption to sample properties as well as reproducible results.
A Drum Mill TM 500 foodGrade model featuring a stainless steel 316L drum and hopper is available for applications where the sample must not be contaminated in any way.

Woven Wire Mesh Sieves – ø 200 mm / 203 mm
The well-proven RETSCH woven wire mesh sieves consist of a solid stainless steel sieve frame of high stability for reliable sieving results. Paying close attention to mesh-specific requirements, the sieve fabric is precisely joined into the frame and tautened. The individual laser engraving of each RETSCH test sieve provides a clear and accurate labeling with full traceability.
The mesh sieves can be easily combined with all other sieve brands. Each sieve that leaves our company comes with a test report or, at your request, with a special inspection certificate in conformity with national and international standards. RETSCH calibration certificates confirm a great number of precision measurements, thus ensuring an even higher statistical reliability for your quality control.
RETSCH test sieves are available in many different diameters, mesh sizes and varieties, primarily in the four frame sizes most widely used in laboratory analytics:- 200 x 50 mm, 200 x 25 mm
- 8“x 2“ (203 x 50 mm), 8“x 1“ (203 x 25 mm)

XRD McCrone Mill
The XRD-Mill McCrone was specially developed for the preparation of samples for subsequent X-ray diffraction (XRD). The mill is used for applications in geology, chemistry, mineralogy and materials science, quality control as well as R&D.
Because of its unique grinding motion, the XRD-Mill McCrone is particularly effective for this analytical method: The 48 cylindrical grinding elements grind the samples gently via friction. The result is a short grinding time with almost no sample loss and an exceptionally narrow particle size distribution. Consequently, the signals in the X-ray diffraction pattern are peak-shaped, with small half-widths, allowing for very good phase analysis.
The crystal lattice structure is largely preserved, with almost no defects, a prerequisite for meaningful X-ray diffraction patterns.The grinding vessel consists of a 125 ml capacity polypropylene jar fitted with a screw capped gasketless polyethylene closure. The jar is filled with an ordered array of 48 identical cylindrical grinding elements, available in agate, zirconium oxide or corundum. The grinding time for optimum micronization is between 3 and 30 minutes. A typical sample volume is between 2 and 4 ml.
