QualityLabs BT GmbH

QualityLabs is an accredited microbiological testing laboratory for the evaluation and certification of antibacterial and (anti-)adhesive properties of surfaces and products.

For over 15 years, the QualityLabs laboratory has stood for its expertise in the fields of microbiology, medical technology and laboratory analysis. We specialize in testing the antimicrobial or anti-adhesive properties of a wide range of products. We have a broad portfolio of established, accredited or standardized tests at our disposal. In addition to our self-developed and accredited methods CERTIKA adhesion and proliferation assay, this also includes many tests according to the following standards: ASTM, JIS, ISO, AATCC or other regulations. 

We regularly expand our portfolio of tests in close consultation with our customers. Feel free to contact us.

We place the highest value on quality, confidentiality, independence and speed. 

All samples are anonymized in our laboratory before testing. 

Antibacterial/ (anti) adhesive testing of medical devices: 

• Determination of antimicrobial efficacy of material surfaces by determining the inhibition of daughter cell release using CERTIKA Proliferation Assay 
• Screening of antimicrobial properties of material surfaces by measuring the inhibition of daughter cell release using cost-effective high-throughput screening method QualiScreen
• Determination of adhesive surface properties. Used to determine the adhesion of microorganisms to material surfaces using CERTIKA Adhesion Assay.

Antimicrobial testing of surfaces and antimicrobial products: 

• Antibacterial efficacy on surfaces according to ISO 22196 / JIS Z 2801
• Antibacterial efficacy on hydrophobic surfaces according to ASTM E 2180
• Antiviral efficacy on surfaces using bacteriophages as a surrogate for various non-enveloped and enveloped viruses
• Antimicrobial activity of antimicrobial products according to ASTM E 2149

Antimicrobial testing of textiles: 

• Antibacterial activity of textile products according to JIS L 1902 / ISO 20743 or according to AATCC 100 / ISO 20645
• Antifungal activity of textile products AATCC 30 Method III

Antimicrobial testing of plastics:  

• Determination of the effect of fungi and bacteria on plastics according to ISO 846
• Efficacy of fungistatic compounds in plastics according to ISO 16869

Testing of paints and varnishes:

• Pot preservation testing of aqueous-based products (ECHA test method) according to IBRG PDG16-007.3
• Testing of in-can preservation according to ASTM D 2574 or ASTM D 4783. 
• Testing the resistance of paint coatings to fungal attack according to ASTM D 5590.

Testing of cosmetics and hygiene products:

• Germination of products using bioburden
• Evaluation of the antimicrobial protection of a cosmetic product according to ISO 11930 microbial load test 

Claim-based tests and in-use tests: 

• Development of laboratory tests (Tier 2) to substantiate claims regarding the efficacy of biocides in treated products. the efficacy of biocides in treated goods - OECD Tier 2 tests
• Determination of the time until a certain germ reduction has occurred by means of a kill kinetics test
• Antimicrobial or antibiofilm effective test specimens can prove whether they prevent the growth of a biofilm using the biofilm reactor test
• Simulated splash test (ECHA)
• Stamp test - printing model (ECHA)
