Endosafe® Endotoxin Testing Cartridges
This technology was designed to streamline and optimize testing by consolidating all the essential components into a single disposable cartridge, to provide real-time, quantitative endotoxin analysis. Available in Endosafe LAL and in 2024 Trillium rCR, with further commitment to the 3Rs by reducing and or replacing the usage of horseshoe crabs.
Endosafe® Endotoxin
Testing Cartridges

The Endosafe® cartridge technology is innovative offering higher sensitivity and faster quantitative LAL testing results. Designed to optimize and refine use of LAL, the cartridge technology eliminates a significant amount of the raw material and accessories required for traditional endotoxin testing methods while reducing time-consuming preparation and technician variability.
Endosafe® Trillium™
rCR Cartridges

The animal-free Endosafe® Trillium™ rCR cartridges are fueled by optimized kinetic chromogenic reagents curated to simulate the natural LAL reaction, fully embracing the significance of sustainability, while accelerating testing times through our scalable suite of rapid, automated testing platforms.
Endosafe® Beta-Glucan Cartridges

The (1,3)-b-D glucan molecules can be found in the cell walls of most yeasts and molds. These glucans contaminate cell culture fluid, yeast protein production, air quality samples, and cellulose filter preparations. Allow us to help you ensure that your product is free of glucans and isn’t triggering false-positive results in the LAL test leading to potential investigations.

A complete and optimized portfolio of extremely precise and reliable LAL and rCR formulations provide increased sensitivity, greater linearity, and superior interference resistance. From raw materials, in-process, through final product release, explore an extensive offering of Endosafe® reagents and accessories to support your testing program.
Traditional LAL Kinetic Chromogenic Assay

Endochrome-K™ traditional LAL kinetic chromogenic assay reagent is a fully quantitative and uniquely stable reagent. The stability of the reconstituted LAL allows for extended bench time and reuse making it a highly cost-effective and rapid solution for endotoxin testing. How could the rapid results of Endochrome-K, advance your laboratory?
LAL Kinetic Turbidimetric Assay

The kinetic turbidimetric endotoxin test is designed to provide accurate and reliable results on even your most difficult products.
