In over 190 countries all over the world, hundreds of thousands of Memmert products have been permanently in use for decades. This is why Memmert is one of the leading suppliers of temperature control appliances worldwide.
¿Almacenar las sondas de alta sensibilidad en una cámara climática con una fluctuación de temperatura máxima de 0,2 K? ¿Acortar los tiempos de secado al vacío? ¿Garantizar la seguridad de las pruebas continuas a largo plazo? ¿Llevar a cabo ensayos con tasas de intercambio de aire definidas? En nuestra página de aplicaciones "Industria" presentamos nuestros equipos Memmert y sus aplicaciones.
El enfoque intransigente en cuanto a calidad ha permitido que Memmert sea, desde los comienzos allá por el año 1947, un socio fiable de la medicina así como de la investigación médica. Por supuesto, Memmert posee la certificación DIN EN ISO 13485 para los dispositivos médicos. Memmert ha superado satisfactoriamente la prórroga de los certificados MDD 93/42/CEE. El organismo designado ha vuelto a expedir el certificado CE existente, la Directiva 93/42/CEE, y ahora es aplicable hasta mayo de 2024 de conformidad con la disposición transitoria (UE) 2017/745. Esta aplicación especial en torno al tema de la medicina muestra los equipos y aplicaciones adecuados.
Es la pasión por el detalle lo que determina la calidad extraordinaria de nuestros equipos con regulación de temperatura. Es el enfoque basado en las necesidades de nuestros usuarios lo que hace que los equipos Memmert sean los acompañantes habituales desde hace décadas de laboratorios farmacéuticos y para la investigación médica. En esta página encontrará estudios de casos y equipos.
Estamos comprometidos en cuerpo y alma con el buen gusto. Para garantizar la extraordinaria fiabilidad y precisión de los incubadores, las estufas de calentamiento y las cámaras climáticas de Memmert, desarrollamos y fabricamos todas las piezas importantes nosotros mismos.

Let us take you into the fascinating world of Memmert appliances, which we have collected on our user platform.
Molecular gastronomy is renowned for using laboratory equipment to create completely new dishes, flavours and textures. Copenhagen’s Alchemist is one of the top international restaurants to have applied this experimental approach as part of a unique culinary signature. In its kitchens, this innovative Danish venue has two Memmert incubators for fermenting ingredients.
The technical cleanliness of functionally relevant components is a central factor in quality management in the automotive industry. For standard-compliant testing of residual contamination, a Memmert drying oven in the mobile laboratory is in use almost constantly.
Where there’s work there’s dirt. In the manufacture of functionally relevant parts for the automotive industry such as gears, transmissions or injectors for diesel engines, tiny metal particles and other residual dirt stick to the components. The components therefore have to be cleaned in costly cleaning units prior to delivery. However, where safety in the vehicle is concerned, trust is good but control is certainly better, which is why the VDFA guideline volume 19, ISO 16232 and numerous factory standards specify how engine manufacturers and other suppliers from the automotive industry must test and document technical cleanliness, that is, residual contamination. At the Kreisel laboratory and consulting service, the Memmert drying oven has become a fixture in the elaborate testing process.
Markus Kreisel, the owner, supports the suppliers of components and the manufacturers of cleaning units in their quality management. With his ISO-certified laboratory trailer, he travels all over Germany and neighbouring countries, performing residual contamination analyses right next to production facilities.
The diameter of a human hair is about 70 µm on average (1 micrometer equals 1 thousandth of a millimeter). The maximum size of a particle of dirt that does not impair the function of the component from a technical perspective is, depending on customer requirements, also in the 2 to 3 figure micrometer range. Determining particle sizes is truly no small matter for Markus Kreisel. Elaborate laboratory appliances and analyses in the cleanroom are a matter of course, also in the mobile laboratory.
For the measurement, particles are captured on a filter membrane that, prior to analysis, Markus Kreisel dries in a Memmert UNB 400 drying oven at 85 °C for exactly 45 minutes, and after cooling down, weighs it on laboratory scales.
In the particle-free analysis device, the components are then rinsed with a predefined pure liquid, after which the dirt particles under vacuum, together with the rinsing fluid, are drawn over the filter membrane. When this has been dried again for 45 minutes at 85 °C in the drying oven, it is cooled off in a desiccator and weighed once more. The difference between the two weighings results in the overall weight of the residual contamination. A further analysis step is the measurement of particles through an automatic microscopic counting of metallic and non-metallic particles.
Since cross contamination of samples must be avoided under all circumstances, purity and hygiene are also the highest priority in the drying oven. This is why Markus Kreisel particularly appreciates the surfaces of stainless steel of his Memmert drying oven and the smooth, easy-to-clean interior. “Cleanliness as a competitive factor” – this applies for the Kreisel laboratory service, for customers from the automotive industry and also for Memmert. www.laborservice-kreisel.de
