Endosafe® nexgen-MCS™

This multi-cartridge benchtop LAL test equipment addresses the need for higher sample throughput while utilizing the same FDA-licensed LAL cartridge technology as the Endosafe® nexgen-PTS. The Endosafe® nexgen-MCS™ is proficient at concurrently testing up to five samples within 15 minutes for rapid, quantitative, and accurate endotoxin results. The Endosafe nexgen-MCS endotoxin testing system is comprised of five individual spectrophotometers built into a unit with a single Ethernet connector that links to your computer running EndoScan-V™ version 5.5.5 or higher, our 21 CFR Part 11 compliant-ready endotoxin measuring software.

Since each cartridge runs independently with the Endosafe nexgen-MCS, you can run your LAL testing samples as needed and not wait for a full batch of samples for testing, obtaining results in approximately 15 minutes.

Advancing Endotoxin Testing with Robotics

Automation through robotics represents a new paradigm for bacterial endotoxin testing, streamlining QC processes and providing widespread operational benefits across many organizations. Since the launch of the first fully automated robotic Endosafe® Nexus™ in 2014, transformations in technology and innovation have inspired our Research and Product Development team to reimagine the next iteration of our automated endotoxin testing system.

The Endosafe® Nexus™ 200 is a fully enclosed, data integrity compliant, walkaway robotic instrument, capable of testing up to 120 samples per run and performing complex and serial dilutions via Endosafe® cartridge technology.

The advantages of implementing automation are no longer just for high-volume, large manufacturing organizations. Robotics help minimize variation, time, and resources of performing both laboratory and out of specification investigations. Improved agility and shorter testing times can reduce lead times for quality control labs by 60-70% and could eventually lead to real-time product releases. By using automated endotoxin testing designed for a GMP laboratory, lab analysts are free to perform high-value activities such as interpreting data, analyzing trends, and proactively addressing risks, all aspects that are highly stressed in Annex 1.
