Sterility & Microbiological Control
Microbiological safety of APIs and pharmaceutical excipients is an irreplaceable core checkpoint in the whole drug research and development lifecycle. Hidden microbial contamination, endotoxin residues and mycoplasma pollution in raw materials will directly cause finished drug quality failure, clinical infection risks and GMP audit non-compliance, hindering R&D progress and market approval. As a professional analytical brand under STEMart, PharmaAnalytica launches full-process Sterility & Microbiological Control services specially for API and excipient scenarios. We rely on a complete closed-loop hardware equipment platform, including high-standard sterilization equipment, constant-temperature microbial incubation systems, professional microbial observation and high-precision strain identification devices. We fully comply with ChP, USP and EP pharmacopeia standards to deliver one-stop microbial safety analysis, effectively blocking raw material microbial risks, stabilizing R&D batch consistency, and supporting smooth regulatory filing and laboratory batch release for pharmaceutical enterprises.
Specialized Sterility & Microbiological Control Services
Sterility Test
Our pharmacopeia-compliant sterility test is specially designed for sterile-grade APIs, injection-grade excipients and raw materials used in ophthalmic and implantable preparations. We adopt closed membrane filtration sterile processing workflow to avoid secondary environmental pollution during sample pretreatment. Equipped with supporting high-efficiency sterilization and constant-temperature culture equipment, we conduct long-term standardized incubation to observe viable microbial growth in test samples. Before each batch of experiments, strict method suitability verification is carried out to eliminate the antibacterial interference of API raw material matrices. The whole operation is completed in A-class clean environment, providing true and reliable sterility judgment data, which meets the mandatory release requirements of sterile raw materials for high-risk sterile preparations in pharmaceutical R&D.
Microbial Limit Test
This service targets routine microbial safety screening of non-sterile APIs, oral solid excipients, herbal extracts and common functional auxiliary materials in drug development. We quantitatively detect Total Aerobic Microbial Count (TAMC) and Total Yeast and Mold Count (TYMC), and simultaneously screen objectionable pathogenic bacteria such as Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa according to dosage form administration routes. Combined with professional microbial counting and morphological observation equipment, we complete accurate colony counting and preliminary microbial differentiation. The test effectively evaluates whether the microbial load of raw materials is within the safe pharmacopeia range, avoiding finished product spoilage and efficacy attenuation caused by excessive microorganisms in the later formulation development stage.
Bacterial Endotoxin Test (LAL)
Our Bacterial Endotoxin Test based on Limulus Amebocyte Lysate (LAL) is a key safety detection item for injection APIs, water for injection and high-purity pharmaceutical solvents in R&D links. We apply standardized gel-clot and turbidimetric quantitative methods to efficiently trace and quantify gram-negative bacterial endotoxin residues in raw materials. The laboratory strictly controls environmental temperature and pyrogen-free operation conditions to prevent external endotoxin cross-contamination. Accurate endotoxin limit assessment effectively prevents pyrogen reactions, fever and shock risks in clinical intravenous medication. It provides core pyrogen safety data for raw material incoming inspection and preclinical safety evaluation of parenteral drugs.
Mycoplasma Detection
Mycoplasma detection is a necessary microbial risk control item for biological APIs, cell culture raw materials and biochemical auxiliary materials in biopharmaceutical R&D. We adopt the combined strategy of liquid culture enrichment, solid culture isolation and molecular biological rapid auxiliary detection to efficiently screen hidden mycoplasma pollution in raw material batches. Relying on high-precision microbial observation and nucleic acid detection supporting equipment, we accurately identify low-level dormant mycoplasma strains that are difficult to observe conventionally. This service avoids cell culture contamination, experimental data distortion and biopharmaceutical product activity degradation caused by mycoplasma, ensuring the stability of biological drug R&D and production processes.
