PREVI® Color

Gram staining is almost always the first step to carry out before the identification of a bacterial organism. Its purpose is to differentiate bacterial species into two large groups : gram-positive and gram-negative. bioMérieux has developed the automated PREVI Color Gram system, an automated gram staining system.

Automated gram staining : breakthrough in microbial identification

PREVI Color is an automated gram staining system. Easy-to-use, it relies on an innovative spray technology which enables rapid, standardized and accurate results for all types of specimen.

Fully automated, this system can perform thorough and reliable gram staining while your staff complete more important tasks : it optimizes your workflow.

Efficiency through automation

Its automated spray nozzles always dispense the same reagent volume which standardizes the coloration. As a fresh staining reagent is used each time and all the slides are separated, no cross contamination is possible. 

In comparison with manual and bath staining, microorganism differentiation is greatly improved with PREVI Color Gram.
