Celsis®, our rapid microbial detection solution, allows you to test and safely release products in half the time of traditional methods for sterility, bioburden, and microbial limits. By providing results in less than 7 days for sterility and less than 2 days for bioburden and microbial limits, Celsis® detects contamination faster, minimising the impact of contamination events on your manufacturing process.

Accelerate Your Path to Rapid Sterility Testing with Celsis® Validation & Implementation Support

Charles River now offers a streamlined pathway to faster implementation of the Celsis® rapid microbial detection method using Celsis AMPiScreen® (Amplified ATP Bioluminescence) for rapid sterility testing. Our two validation support packages are designed to demonstrate method equivalency, reducing the time to validation by 3 to 6 months. This accelerated timeline allows you to transition from installation to routine use of your Celsis® rapid detection system more quickly, enabling you to realise the benefits of rapid sterility testing sooner.

Charles River’s Accugenix® microbial identification and strain typing services offer unparalleled accuracy in identifying microbes with the most relevant reference libraries of bacteria, filamentous fungi, and yeasts. Specialising in bacterial and fungal identification and strain typing of environmental isolates, we use the latest DNA sequence-based and MALDI-TOF technologies to provide accurate and reliable microbial identification services to more than 1,000 facilities worldwide. Our flexible solutions allow clients to outsource to our experts or use our services in-house.

Specialised services

With more than 70 sites around the globe, Charles River is strategically positioned to coordinate worldwide resources and apply multidisciplinary perspectives in resolving your product’s unique challenges.
