Bioburden Testing

Bioburden and microbial limits testing assess the resident microbial levels in your pharmaceutical and medical device products and ensure the absence of specified pathogens. A robust evaluation of recovery method suitability validates the testing in your product matrix and supports your need for regulatory compliance, quality assurance, and overall product safety.

Endotoxin Testing

Endotoxins are a type of bacterial toxin that can cause serious illness, especially in people with weakened immune systems. To ensure the quality of your parenteral drug formulations, medical devices, raw materials, excipients, water, water for injection, and APIs, our experts offer testing for the detection and control of endotoxins. Bacterial endotoxin testing (BET) is crucial to uphold the quality and safety of your products.
