Customer-specific solutions

Does our existing range of products not meet your requirements? Please contact us. We would love to hear more about your distinct application. Tailor-made solutions are our business. We will work with you to create an optimal solution for your shaking machine or shaken bioreactor system (OSB).

Do you have an unconventional or self-made shaking vessel? Send us a prototype of your vessel and we will develop a clamp that fits.

Would you prefer to combine your measuring system with one of our shakers? Do you require a shaking machine with an unconventional feature? We will adapt our shakers to fit your needs.

Application-oriented consultation

In addition to our products, we offer a comprehensive consultation concerning cultivation in shaken bioreactors.

We have several in-house laboratories for application and long-term testing of our products. In these labs, we work with computer-based models, apply online measurement techniques or generate experimental data for our library. Thus, we are prepared for any questions regarding our products or cultivation in shaken bioreactors in general.  Thanks to our partnership with renowned research facilities, (e.g. Chair for Biochemical Engineering, RWTH Aachen University, GER) we can also offer solutions for complex cultivation problems.

Consultations are free of charge for our customers and of course confidential. For prospective customers, we offer an initial consultation free of charge.

Kuhner Seminars and (Online-)Trainings

As part of our comprehensive customer service and support, we also offer our customers scientific seminars on application-related questions and issues, and tailor-made training courses for our shaking machines and orbital shaken bioreactors. Our scientific seminars cover all kinds of topics about cultivations in shaken bioreactors such as shake flasks, microtiter plates, and orbital shaken bioreactors. Frequently asked questions and other topics are discussed and backed up with scientific evidence. The training courses can be either conducted at one of our own training sites, on-site at the customer’s premises, or online. Each training course will be adapted specifically to the customer’s demands.

If you would like to be notified about future scientific seminars or you are interested in a specific seminar or training for your employees, please contact us:
