Ensuring microbial control in your product and manufacturing environment is critical for maintaining safety, efficacy, and regulatory compliance. Capital Biolabs provides precise and validated testing services for the detection and quantification of microbial contaminants, including bioburden and endotoxin, in a wide range of pharmaceutical and biotechnology products.
Our microbiology team adheres to ISO and USP <61>, <62>, and <85> standards to deliver reliable, defensible data that supports batch release, routine monitoring, and validation studies.
Disinfectant Efficacy
At Capital BioLabs, our Disinfectant Efficacy Testing services are designed to verify that your cleaning and disinfection program effectively controls microbial contamination across critical environments. Using validated methodologies and industry-recognized standards, we evaluate disinfectants, sporicides, and sanitizers to confirm they achieve the required reduction in microbial load on representative surface types.
Our testing is performed in accordance with USP <1072>, ASTM E2315, and AOAC methods to assess both suspension and surface efficacy. We test against environmentally recovered isolates as well as reference microorganisms, ensuring that your disinfectant program is not only compliant but also relevant to your facility’s unique microflora.
By partnering with Capital BioLabs, you gain defensible data to support qualification, rotation, and validation of disinfectants, providing confidence that your contamination control strategy performs as intended within your controlled environments.

GMP Cleaning Services
Maintaining a controlled, compliant, and contamination-free environment is critical to every pharmaceutical, biotechnology, and cleanroom operation. Capital BioLabs provides GMP-trained Cleanroom Technicians who deliver reliable, validated cleaning services designed to uphold the highest standards of cleanliness and regulatory compliance.
Microbial Challenge
Microbial Challenge Studies are a foundational tool in pharmaceutical microbiology used to evaluate the microbial growth potential of drug products following preparation, reconstitution, or container penetration. These studies generate critical data that support safe hold times, preservative performance, and storage condition validations, all essential for maintaining product integrity and patient safety.
Adapted from USP <51>, microbial challenge testing is non-compendial: a low-level inoculum of microorganisms is introduced to a product to simulate possible contamination, and samples are periodically assessed to measure microbial proliferation. The growth potential is deemed acceptable if there is no more than a 0.5 log₁₀ increase relative to the inoculum control.
These studies are especially useful for:
Sterile, non-preserved products, such as reconstituted lyophilized drugs or admixtures
Defining in-use or hold-time limits between preparation and administration
Evaluating preservative system robustness and formulation resilience
Establishing optimal storage and handling protocols to mitigate microbial risk
In designing a microbial challenge, key parameters include the formulation matrix, diluent type, storage temperature(s), and target microbial strains. Testing typically includes the USP <51> organism panel, supplemented with skin flora and nosocomial pathogens, and timepoints are selected to exceed two to three times the intended hold duration to fully evaluate growth dynamics.
To align with industry expectations, our design and interpretation also draw on Parenteral Drug Association (PDA) technical guidance.
At Capital BioLabs, our microbiologists leverage expertise and recognized frameworks to execute rigorous microbial challenge studies. We deliver defensible, data-driven results to support your contamination control strategy, regulatory documentation, and product risk assessment.
