Benefits of the PRS 3 Microplate Reader
Enhanced Testing Capabilities
By leveraging our unparalleled LAL and rCR reagents, this instrument provides accurate and reliable quantitative endotoxin test results while meeting today's stringent testing requirements. Users can effortlessly switch between every Endosafe reagent, facilitating faster and more reliable testing.
Promoting Sustainability with Endosafe Trillium rCR
Integrating environmentally conscious alternatives into your testing workflow is now simpler than ever with recombinant reagents like Endosafe Trillium. Clients can ensure product safety while prioritizing sustainability. The PRS 3 system allows users to seamlessly transition between LAL and rCR vial-based reagents, offering flexibility to test multiple samples with different reagents.
Seamless Endosafe EndoScan-V Integration
Endosafe EndoScan-V Version 6.2 and above perfectly align with 21 CFR Part 11 regulations, providing extensive and searchable audit trails for electronic records. This software enables users to effortlessly implement, integrate, and comply with data integrity guidelines on a global scale. The combination of the PRS 3 system and EndoScan-V software streamlines the process of generating accurate raw data analysis for reporting, tracking, and trending bacterial endotoxin testing.
Effortless Usage & Low Maintenance
With the PRS 3, there's no need to worry about replacing halogen bulbs or dealing with filter changes. Equipped with a long-lasting xenon flash lamp light source, this instrument ensures consistent performance throughout its lifetime. Moreover, the single monochromator filter covers a wide range of UV wavelengths, from 200 nm to 999 nm, enhancing sample processing efficiency and minimizing downtime.
Self-test Reporting for Added Convenience
Each time the instrument is powered on, an on-board diagnostic self-test automatically runs, guaranteeing optimal functionality. Users can generate and print self-test reports within the EndoScan-V software for easy reference. Calibration test plates are also available for purchase, providing clients with the option to perform additional checks. Our dedicated support teams are always ready to assist you with any inquiries.

Endosafe® Trillium™ rCR Technical Report
To further demonstrate the robustness and validity of our Trillium rCR matrix and formulation, we published a technical report detailing the results of our comprehensive beta test study program. The report highlights assay equivalency to our FDA-licensed kinetic LAL assay via our primary alternate method validation.

Microplate Reader Instruments & Support
We are committed to providing clients with a simple upgrade process from the BioTek ELx808 Microplate Reader. A full equivalency study has been completed between ELx808 and PRS 3 for bacterial endotoxin testing using LAL and rCR reagents. Our technical support team qualified the instrument for compatibility with EndoScan-V software for bacterial endotoxin testing using LAL and rCR reagents. This service provides a smooth transition for replacing a BioTek microplate reader instrument for BET testing. Our onsite annual qualification of the instrument and software provides the assurance that it is operating correctly and fulfills the recommended preventative maintenance.
Agilent Technologies has discontinued the BioTek Incubating Microplate Reader Model ELx808. As we continue to partner with Agilent Technologies, they have guaranteed service support of the ELx808 through January 2029.
