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. The PREVIĀ® Color Gram system is an automated gram staining system. It is easy to use and relies on an innovative spray technology which enables rapid, standardized and accurate results for all types of specimens. Fully-automated, the PREVIĀ® Color Gram system can perform thorough and reliable gram staining while your staff complete more important tasks. The spray nozzles always dispense the same reagent volume which standardizes the coloration. The protocol is rapid and high throughput with up to 300 slides per hour. Reagent and water demand are low and the system is closed - no human contact with reagent.
