We’ve purposely built our QC Microbial Solutions portfolio to bring you progressive products and services that deliver accurate, relevant and reliable data to fuel confident decisions on product quality and contamination control. Our unique combination of Endosafe® endotoxin testing, Celsis® rapid microbial detection, and Accugenix® microbial identification keeps your manufacturing operations running efficiently and smoothly, lowers your cost to manufacture, and protects your reputation.

Our products

The Endosafe nexgen-MCS is a multi-cartridge endotoxin detection system that uses FDA-licensed Endosafe® LAL cartridges for fast, quantitative, and accurate endotoxin results

Our Endosafe® systems simplify endotoxin detection from in-process to final lot release testing with flexible solutions to meet the needs of every customer, regardless of sample volume or industry. Our easy-to-use Endosafe® products increase efficiency in the LAL laboratory by delivering rapid, accurate results. Every system we sell is backed by our skilled technical team who can provide training and maintenance.

A Celsis® rapid microbial detection system can provide accurate micro results in 18–24 hours, cutting days from your production cycle and helping to significantly reduce costs—without sacrificing quality. By confirming product quality significantly faster than traditional methods, product moves more quickly and efficiently into distribution. In the event of a contamination, you can accelerate corrective action and get back on track sooner. Celsis® instruments are in use in over 600 locations worldwide by the world’s largest manufacturers, including Proctor & Gamble, Unilever, and many more.
