Microbiological testing requires special equipment, experienced people, and specific quality procedures. Contamination of samples must be avoided. QUERCUS Labo provides you with all of this plus verified excellent quality for both routine testing and stability studies. All actions are meticulously recorded, quality control is maximised, and every precaution taken to ensure reliable results.

A most efficient organisation ensures that all tests are initiated immediately upon arrival of the samples at QUERCUS Labo with reporting sent out at the moment that test results are available.

QUERCUS labo test the microbial quality of raw materials and non-sterile pharmaceutical forms: microbial count, exclusion of specified germs with identification, efficacy of microbial preservation.

QUERCUS labo has also a broad experience in microbiological assay of antibiotics. However HPLC is the method of first choice for the assay of many antibiotics, some antibiotics still require a microbiological potency testing.
