We have done extensive work with Ciba Expert Services. They have done a lot of the hazards testing for us and are involved in doing the REACH suite of testing for a number of materials for us. We evaluated a number of companies and they where our pick after some rigorous screening. During the evaluation I did notice that they had a lot of experience with different forms of chemistry and they maybe very suited to help you with your challenge. The contact there is Dean Hamel at dean.hamel**At_Symbol_Here**

My company is looking to perform some toxicity testing on some of our monomers for the dental industry (not FDA testing).& nbsp; Does anyone know of good companies that perform such testing?

We had also looked at this particular test< /P>

ISO 7405:2008 contains a cytotoxicity test method common to the dental industry.

Are there any others that are recommended?  Is this a good test to have done?  I appreciate any insight you may have in this area.
