Sample Preparation

As the summer season approaches, interest in swimming in the sea, lakes and rivers continues to grow. Yet behind water that appears clear can hide invisible microbiological hazards, posing a real risk to public health.

Every year on June 5, people worldwide come together to mark World Environment Day, a global initiative led by the United Nations to raise awareness and drive action for the environment. While forests, oceans, and wildlife often take center stage, one form of biodiversity is usually left out of the picture: microorganisms. The microbiome: the […]

Multi-Tissue Dissociation remains one of the most critical and complex steps in preparing samples for cell-based assays. Inconsistent performance across tissue types, low cell viability, and poor reproducibility often compromise the quality of downstream analysis. As research in cellular physiology, pathology, and regenerative medicine becomes increasingly sophisticated, achieving reliable and standardized tissue processing is more […]

The invisible Biodiversity When we think of biodiversity, we often picture tropical forests, coral reefs, or endangered species. But one of the richest and most essential ecosystems on Earth is invisible: the microbiome. These microbial communities, like bacteria, viruses, fungi, and archaea are everywhere: in the soil, in fermented foods, and inside our bodies. They […]

In 2025, Precellys celebrates 20 years of innovation in sample preparation and homogenization. Since its creation, it has established itself as a trusted solution in diverse fields such as pharmaceutical research, forensics, environmental analysis, and cosmetics.  From the very beginning, Precellys was designed to meet a fundamental laboratory need: efficiently homogenizing samples while ensuring reliability […]

Ghrelin, widely recognized as the hunger hormone, is now under the spotlight for its role in mental health. Recent studies suggest that this metabolic signal may influence mood, especially in individuals with major depressive disorder (MDD). This connection between ghrelin and emotional states reveals new possibilities for understanding the gut-brain axis. Ghrelin levels rise during fasting […]

Microplastics are not just contaminating oceans—they are also present in the air we breathe. However, detecting and quantifying these invisible particles remains a major scientific challenge. A recent study by Dimitri D. Deheyn, Joe Ayesu, The Or Foundation, and Branson Skinner at the Kantamanto market in Accra, Ghana, revealed an alarming concentration of 500 airborne […]

How to optimize bone sample preparation for metabolomics You know how crucial it is to reveal the hidden biochemical signatures in bone samples to unlock mysteries about past lifestyles and environmental exposures. Yet, complex bone matrices often lead to challenges that risk compromising your valuable material. Preserve sample integrity with advanced homogenization Precellys Evolution Touch […]

Challenges in Pharmaceutical Development Improving the dissolution, solubility, and bioavailability of poorly soluble drugs (BCS Class 2) remains a significant challenge. Amorphous Solid Dispersions (ASDs) are a promising solution, stabilizing drugs in their amorphous form using polymers and low-molecular-weight excipients. However, thermodynamic instability and complex processing steps make their preparation difficult. Limitations of Conventional Methods […]

The rise of fentanyl and its analogs has led to a major public health crisis, making reliable detection methods essential for toxicology labs. Our latest Application Note presents an optimized workflow for analyzing synthetic opioids in hair samples, using the Precellys homogenizer and Bertin’s lysing kit. A Major Analytical Challenge Fentanyl is 50 times more […]
