For organisms that are difficult to gram stain

LanaGram™ produces a rapid color change in a tube, gram negatives turn yellow, gram positives remain clear. Ideal for Bacillus, Listeria, Lactobacillus, and non-fermentors, all of which can be difficult to gram stain.

The Hardy Diagnostics manufacturing facility and quality management system comply with the FDA's Good Manufacturing Practices (GMP) and have achieved ISO 13485 certification as a medical device manufacturer.
