Innovation--Producing according to the state-of-the-art         

A development engineer at DIOSNA needs to have many qualities:
a thorough scientific training, a few years experience, an inventive mind and above all a feeling for market requirements – and the skill to develop successful solutions for them. 

DIOSNA has already come up with numerous patents and new achievements in pharmaceutical technology.
For example we have developed the first vertically rotating film coater (VCC) to market maturity. DIOSNA also creates less spectacular new products: control systems, for example, which enhance operating friendliness and therefore reduce errors.

In order to keep up to date in our developments we are in I constant contact with universities, technical institutes and colleges. This approach provides wide ranging skills and expertise from different areas of research for your production technology.

Philosophy--We make things difficult for us, to make things easier for our customers

DIOSNA has earned itself a good reputation in international pharmaceutical technology by consistently following market requirements. Every plant or machine made by DIOSNA meets two of our customer’s essential demands: firstly for high technological perfection, secondly for greatest possible application safety. 

With each plant we ask ourselves: Can it be operated safely by someone who does not use it every day?

The thing that stands out about DIOSNA plants is the resolution of apparently irreconcilable requirements: highly complex technology and simple handling. Maximum output with minimum errors. 
Sensitive control and robust processing. Cost reducing standardisation and value increasing individualisation. Not an easy route, but the one which brings our customers most benefits in the long term.


Quality--We make things difficult for us, to make things easier for our customers


Customer satisfaction is our top priority. DIOSNA certifies according to DIN ISO 9001. Therefore the assurance, documentation and improvement of existing quality standards for our products and services is a main feature of our company’s philosophy to meet our customers’s requirements.


This quality demand does not only apply for well-founded application technical consulting but also for tests in our laboratory, planning and construction of plants as well as for the entire production process.


For the pharmaceutical industry DIOSNA offers comprehensive qualification services for trouble-free validation. The specified steps comprise documents for the independent qualification by our customers themselves to qualification according to GAMP 5. The validation of our computer systems according to 21 CFR Part 11 is of course also included in our services.
