  • Análisis por tamizado - El "patito feo" del laboratorio moderno

    Con el equipo y el software adecuado, el análisis por tamizado es una técnica analítica que va más allá de proveer datos granulométricos rápidos, exactos y reproducibles.
  • Small particles help to preserve the Cologne Cathedral

    The Cologne Cathedral is a venerable old building whose historic substance is preserved by continuing restoration works. Mortar is one of the construction materials that the conservators use for preservation and restoration of the ancient stones. To obtain mortar with optimum quality, the conservators at the cathedral workshop in Cologne use a RETSCH sieve shaker to determine the particle size distribution of the material.
  • Particle size - a quality feature

    The determination of the particle size distribution of a product has always been of great significance in food production. Taste, color, solubility or extraction behavior are only a few examples of product properties which are directly influenced by particle size. Traditionally, analytical test sieving provides a quick and simple possibility to characterize the particle size of bulk goods. In the testing laboratory of the St. Petersburg branch of LLC Wrigley RETSCH sieve shakers AS 200 jet and AS 200 control are utilized for particle size analysis of fine powders which are used for chewing gum production.
  • Measuring Dust - Incoming Inspection with Sieve Analysis

    Graduate student Jennifer Franz has developed a new inspection procedure during her work at the German food producer Lebensgarten GmbH. With the help of sieve analysis the company can now reliably ascertain the fines and dust fractions of incoming cereal flakes; these have a negative influence on the mixing and packaging process of muesli.
  • Renewable energies on the rise

    Sample preparation of vegetable-based raw materials with laboratory mills

    Thanks to the increasing usage of biomass as a source of energy, the analysis of these materials in the context of R&D and quality control gains importance, too. Due to the complex properties of plant materials, adequate sample preparation can be rather a challenge.
  • Down to the bone

    Use of laboratory grinders for size reduction of human bones and bioceramics

    Bone implants and substances for bone regeneration are used in surgery to replace degenerated bone material by implants or to “re-build” it with specific substances. The material used in implants varies from autogeneic (supplied by the patient) through allogeneic (supplied by a donor) bones to replacement materials such as hydroxylapatite (HA) and tricalcium phosphate (TCP). Bovine bones and corals are used in conjunction with synthetically produced foamed materials to form a basis for the regeneration of bone substance. Various RETSCH mills are suitable for the preliminary and fine grinding of human bones as well as bioceramic materials.
  • Recycled glass - a valuable resource

    Today, recycled glass is the most important resource for the glass industry. The processed glass can be reintroduced to the melting process any number of times and made into new products. In Germany, currently up to 95 % of recycled glass is used for producing glass, which has various advantages: energy saving, less consumption of primary raw materials (such as lime and silica sand) and the reduction of landfill costs for waste glass.
  • The Basic Principles of Sieve Analysis

    Many natural and manufactured materials occur in a disperse form, which means that they consist of differently shaped and sized particles. The particle size distribution, i.e. the number of particles of different sizes, is responsible for important physical and chemical properties.
  • Reproducible Sieving in the Shortest Possible Time

    Despite the rapid development of modern optical particle measuring techniques, classical sieving analysis is still at the forefront for the practical quality assurance of bulk goods.
  • Fine Tuning Sieve Analysis for Accurate Particle Size Measurement

    All to often, this useful method is overlooked. But if followed, these principles deliver accurate and reliable results at an affordable price.
