bioMérieux Launches PREVI™ Color Gram Automated Gram Stainer
bioMérieux and Wescor signed an agreement making bioMérieux the exclusive distributor of PREVI Color Gram for Wescor. With this OEM (original equipment manufacturer) agreement, bioMérieux brings automation to a new level in the pre-analytic process with the unique slide staining technology, PREVI™ Color Gram.
Gram staining is a critical and mandatory test performed in the microbiology laboratory. It is a preliminary step used to differentiate Gram-positive and Gram-negative bacteria. A cumbersome and long procedure, traditional Gram staining requires technical expertise, numerous manual steps and therefore lacks reliability and reproducibility. Wescor’s automated spray technology saves time and enables standardization and accuracy of results. The addition of the Cytopro® rotor to the slide stainers results in a cytocentrifugation with eight-slide capacity. The innovative technique also improves laboratory workflow and generates significant savings for laboratories of all sizes.
The PREVI Color Gram will provide the following benefits:
• Produce slides that are dry and ready to read
• Reduce reagent usage
• Create a cleaner environment
The PREVI Color Gram complements a complete range
of fully automated solutions for the microbiology bench, with recent innovations such as the Previ™ Isola for PPM streaking
and Sysmex UF-1000i for
urinary screening.
About Centrifugation, Gram and Mycobacteria Staining
Properly Gram-stained preparations can quickly give you considerable information that can be applied immediately to patient care. The Gram stain is particularly useful in the presumptive diagnosis of bacterial meningitis, bacterial pneumonia, bacteriuria, gonorrhea, and infections of the
brain, lung, abdomen, and wounds.
The Cytopro Cytocentrifuge rotor uses centrifugal force and three unique patented chamber designs to sediment cells onto the slide. With the standard volume (single or dual) chambers, suspension fluid is simultaneously absorbed into the Cytopad® absorption pad as cells contact the microscope slide. The recently introduced high volume Cytopro Magnum™ chamber is easy to use and also retains the excess fluid from a suspended sample.
