Biological Laboratory
We specialize in biological agents – particularly mold and algae in construction. Our main activities include their identification on internal and external building surfaces and in indoor air, including accredited sample collection. Our services are complemented by testing material resistance to mold and algae infestation, and testing the effectiveness of remediation products. We also offer ecotoxicity tests.
Our laboratory provides certified services in accordance with European standards and our own accredited procedures.
