Analytical Centrifugal Filtration

LUM GmbH was founded in 1994 by the Managing Director Prof. Dr. Dietmar Lerche as innovative development, production and service corporation. The headquarters are located in Berlin, Germany. The company has an office and application laboratory in France and three subsidiaries: LUM Corporation, USA, LUM (Changzhou) Instruments Co. Ltd, China, and LUM Japan Co., Ltd. LUM GmbH consists of a highly qualified, multidisciplinary team of scientists, technicians and engineers. Scientific and measurement-technology expertise has been obtained for decades in: •Particle characterization •Analysis of suspensions and emulsions, including stability evaluation •Determination of adhesive and bonding and strengths •Quality assurance and process optimization. This knowledge and its continuous extension form the basis for customer-oriented problem solving, product developments and services for our national and international customers, working in larger industrial, food, cosmetics, pharmaceutical enterprises and increasingly in the academic sector. The innovative analytical instruments “made by LUM“ are part of standard laboratory equipment in many R&D and QA/QC departments. LUM instruments enable our customers successfully to develop and formulate new and improved products and introduce them onto the market, following our slogan “The Next STEP in Dispersion Analysis and Materials Testing“.

To achieve the best filterability for a special application, a filter material with tailor-made structure has to be developed. For the design and dimensioning of filtration processes, a new possibility for filtration experiments is to perform the filtration experiments by means of analytical photo-centrifugation filtration (ACF). It allows a simple & fast membrane characterization and filterability with suspensions of about 1 ml. A special developed filtration cell holds the suspension that has to be filtered, the filter media and as well as the resulting filtrate. By adjusting the instrument parameter by applying different rotor speeds (influencing the applied pressure) at different time stages or temperature profiles during one experimental run makes the design very flexible. In the shortcourse: Analytical Centrifugal Filtration (ACF) LUM GmbH expert Sebastian Boldt will train an exclusive group on 12 June from 9 am to 3 pm. You are kindly invited to join.
