PHARMA LAB · PL-02

Microbiology & Sterility Laboratory

From the sample to a meaningful microbiological result.

Connect methods, equipment and workflows in the pharmaceutical laboratory. Explore sterility testing, bioburden, endotoxins, culture media and microbial identification, with a practical focus on evidence, routine controls and investigations.

Sterility testing isolator, filtration system and incubator in a pharmaceutical microbiology laboratory.

Explore the sample journey.

Start with laboratory organisation, testing, materials, sampling or result reliability.

01

Laboratory organisation

Personnel, material and sample flows; responsibilities, functional separation and equipment selection. Define the laboratory workflow without turning an operational plan into a facility engineering specification.

02

Sterility testing & isolators

Membrane filtration and direct inoculation, filtration systems, isolators and biodecontamination. Connect method selection and aseptic controls with the investigation of a positive sterility test.

03

Microbiological methods & technologies

Bioburden, endotoxins and sample interference, rapid methods, microbial identification and colony counters. Start with intended use when assessing performance, limitations and implementation.

04

Media, strains & incubation

Culture media preparation and storage, growth promotion testing, reference strain management and incubation conditions. Follow materials and samples through to reading and interpretation.

05

Sampling & sample handling

Microbial air samplers, receipt of environmental monitoring samples and surface recovery. Focus on equipment and the sample pathway, rather than the design of the entire monitoring programme.

06

Equipment & result reliability

Laboratory autoclaves, biological safety cabinets and laminar flow clean benches; microbiological OOS investigations, outsourced laboratories and personnel competence. Distinguish equipment performance from test reliability.

A clear boundary between laboratory and facility.

This domain follows the microbiological sample. Incubator qualification and mapping belong to laboratory equipment; environmental monitoring strategy and production sterilisation systems remain within Pharma Engineering.
