Biocalorimetry enables rapid and highly sensitive microbial detection in consumer goods, overcoming the long delays and limitations of traditional culture-based sterility tests. By measuring microbial metabolic heat in real time, the calScreener® can confirm contamination within hours, even in complex formulations such as hand wash, shower cream, and toothpaste. This approach reduces production risks, improves quality control efficiency, and supports faster, more reliable release of safe consumer products.
