Zell Kontakt is a German company making fantastic glass bottom dishes and plate. Check out why the LCI facility likes their products (absolutely no commercial interests!).
Great products but crap communication skills! Either their website is down or they do not answer the phone and emails and anyway if they do, make sure you have a German colleague around because no one speaks English.
Now we have found a way around the problem: MoBiTec sells Zell Kontakt products. 🙂
If you are at KI and need to find a KI-certified supplier, just come and ask us. 🙂
