Laboratory LS SE & Co. KG has over three decades of laboratory experience. Methodological competence, our extensive equipment and one of the most modern clean room testing facilities make the company one of the largest providers of microbiological and biological purity testing for sterile drugs and medical devices in Europe. We offer our customers the following spatial testing options:

We examine virtually the entire spectrum of sterile drugs and medical devices according to the current technical standards and have established the appropriate methodological solution approaches for each matrix via membrane filtration or direct feeding.

We conduct the sterility test for you in accordance with the respective current specifications of the common pharmacopoeias:

• JP Section 4.06

• various ISO standards, in particular pursuant to ISO 11137

In addition to classic sterility testing with the required 14 day incubation time, we have extensive rapid methods for each matrix in our portfolio:

• BACT/ALERT® (7 days incubation time)

• Celsis® ATP bioluminescence (7 days incubation time)

• Solid phase cytometry (1 day processing time)


Of course, we would also be pleased to advise you on quality assurance issues in the manufacturing and filling of sterile products.
