PREVI® COLOR GRAM by bioMérieux: an automated Gram staining system for greater precision, safety, and efficiency
The PREVI® COLOR GRAM by bioMérieux is an automated Gram staining system designed to enhance laboratory performance while ensuring perfect standardization. It replaces the traditional manual method with a reliable, safe, and reproducible automated process. With its closed system and ready-to-use reagents, it minimizes chemical exposure risks, ensures full traceability of each cycle, and delivers consistent results regardless of the operator.
Its main advantage lies in the consistent quality of the stains produced. Whereas manual methods can vary depending on the technician or timing of reagent application, the PREVI® COLOR GRAM guarantees standardized and precise application. Smears are clearer, microorganisms are better differentiated, and microscopic analysis becomes more reliable. This consistency is essential for accurate diagnostics, targeted treatment, and seamless laboratory procedures.
Easy to operate, the device features a straightforward workflow: slides are placed in a carousel, the staining protocol is selected via an intuitive interface, and the machine takes care of all staining steps automatically. The time savings are significant — up to 30 slides can be processed in just 6 minutes, with minimal manual handling. This frees up valuable technician time and streamlines lab operations.
Beyond its performance, the PREVI® COLOR GRAM fits perfectly into a cost- and space-optimized laboratory environment. It uses a small amount of reagents, generates minimal waste, and requires very limited daily maintenance. It also offers great operational flexibility, supporting partial or full batch modes and allowing the programming of different protocols to suit the lab’s needs.
Lastly, its 2-in-1 functionality enables it to also serve as a cytocentrifuge. With a dedicated rotor, it facilitates the concentration of biological samples such as cerebrospinal, synovial, or pleural fluids, enabling rapid and effective microscopic preparation.
The PREVI® COLOR GRAM is much more than just a Gram staining device — it is a complete solution designed to improve the quality, safety, and efficiency of microbiology workflows, while adapting to the practical needs of today’s laboratories.
