Our core competence, microbiology, is at the centre of our services. In addition to microbiological and biological tests, we now offer a wide range of chemical-physical and technological test procedures for quality control.

As a provider of laboratory services, we supply an extensive range of standard test procedures and advise customers on quality and process optimisation—both in production and laboratory-related questions. We support them in the creation and practical implementation of their concepts.

Microbiological Testing – Sterile Products

Labor L+S AG is one of the largest suppliers of microbiological and biological purity tests for sterile pharmaceuticals and medical devices. Our sterility tests  are conducted in four aseptic isolators and a clean room (class A in B). The combination of about three decades of laboratory experience, the related methodological expertise and our extensive technical equipment cover the full range of testing services for sterile, endotoxin and pyrogen testing.

Microbiological Testing – Non-Sterile Products

Depending on product and category, non-sterile preparations need to fulfil certain minimum requirements for microbiological purity in order to become marketable. For this purpose, specifications for different dosage forms and preparations have been defined in the common pharmacopoeias and standards, in which the permitted total load of viable microorganisms is stipulated.


Biological Testing

Determining the absence of endotoxin or pyrogen is compulsory for the quality assessment of sterile dosage forms. Similarly as with pharmaceuticals, the absence of endotoxin is one of the criteria for sterile medical devices. Labor LS offers a wide range of biological purity tests for pharmaceuticals and medical devices. These include, for example, tests for endotoxins, tests for pyrogens and monocyte activation tests (MAT) for the control of sterile products. In addition, we determine the biological activity of insulin according to USP <121>.


Chemical and Physical Testing

A team of around thirty experts and laboratory personnel conducts extensive analytical services for customers from the pharmaceutical, medicinal products and cosmetics industry—always in compliance with the relevant regulations. Whether limit testing, purity tests, identification tests or the determination of content, melting point and osmolality—Labor LS offers its customers pharmacopoeial test methods, whose range is extensive in terms of both quality and quantity.


Consulting and Training

In keeping with our diversified range of services and methods, we have steadily expanded our consulting expertise in the three decades since our foundation. Always abreast of the latest developments and changes in the regulations and directives applicable to the various industries, Labor LS offers its vast experience in the (micro)biological and chemical analysis of product quality to its customers.
