Our field of operation
Topas has been established on the American market for over 30 years with series devices and testing systems for classifying and testing filters and filter media. Our American customers can use this technology to verify their quality assurance, optimize their products, and expand their research. With Topas Inc. in Minnesota, we offer this expertise combined with first-class local service.
How to classify your cleanroom
As experts for cleanroom classification and validation since years, we clearly understand your needs:
- What equipment do I need for an cleanroom inspection?
- What are the advantages of particle counters over photometers?
- What is the basic procedure for the required cleanroom tests?
- What are the key differences between ISO Standard 14644 and GMP Annex 1?
During the webinar, we can equip you with the skills to tackle these challenges. See for yourself and register for our webinar:

Extreme conditions are no problem for us
The requirements of ISO 29461 could hardly be more stringent. With our test system for turbomachinery filters, we meet these requirements and offer testing in accordance with all four sections of the standard. Simulating real-world extreme conditions in coastal or desert regions through tests involving salt, water, or dust is no problem for our GTS 114 test system. TOPAS stands for “technology orientation” — and we’ve proven that once again.
You can find more information about the various tests, the individual stages of technological development, and our developers’ ideas on our new explanatory page.
