They are durable, robust, precise, reliable and user-friendly. The quality characteristic of cleanroom-suitable can now be added to the properties which describe our appliances.
In the standard version the Memmert drying ovens UFP 500 and UFP 800 were certified by the Fraunhofer Institut with the IPA cleanroom seal of approval. To guarantee the maximum level of quality assurance, tests were performed in accordance with the uniform and statistically reliable standard of the VDI (Association of German Engineers).
Guido Kreck, project manager at the Fraunhofer IPA in Stuttgart, points to the large significance of the recirculating air system during measurements: “A forced air circulation optimises the homogeneous temperature distribution inside the chamber, yet this is simultaneously the critical issue for the cleanroom suitability of drying ovens.“ Even with maximum recirculating air, the Universal ovens UFP 500 and UFP 800 attain the ISO class 7 in accordance with DIN EN ISO 14644-1, without recirculating air they are certified in the chamber with ISO class 4. In the surroundings, both appliances attain purity class 5.
