The FRITSCH ANALYSETTE 18 is a robust Heavy Duty Analytical Sieve Shaker designed for efficient sieving of large sample quantities up to 15 kg, with a particle size range from 20 µm to 125 mm. Its unique three-dimensional sieving motion combines vertical and horizontal vibrations generated by two unbalanced motors working in phase opposition, ensuring fast, thorough sieving without manual re-sieving and excellent reproducibility. Suitable for dry sieving and wet sieving with a conversion kit, it is ideal for particle size analysis and portioning of coarse-grained materials, including use in pilot production or serial analysis. The system features automatic amplitude control, precise motor braking, and supports sieve stacks up to 42 kg, making it a reliable, high-performance solution for demanding laboratory and industrial applications.
