QuEChERS using the Geno/Grinder

The QuEChERS method is routinely used in thousands of food safety and crop research labs around the world for extraction of pesticide residues and other organic contaminants or compounds of interest. This webinar will cover the theory of QuEChERS and how this technique can be improved using the Geno/Grinder followed by a live demonstration.

High-throughput Tissue Homogenization & Cell Lysis Using the Geno/Grinder® and MiniG®

We discuss how the Geno/Grinder and MiniG can be used for effective tissue homogenization and cell lysis for a range of different sample types. Applications include DNA/RNA extraction and pesticide residue extraction.

Sample Preparation for Hemp and Cannabis

We discuss theimportance of sample preparation for hemp and cannabis testing.

Restricted Elements in Imported Children's Toys

The recording of our webinar entitled, "Identification, Preparation and Analysis of Imported Plastic Children's Toys for Restricted Elements." Topics of discussion include: Plastics Identification Sample Toy Preparation Sample Digestion Analytical techniques for determining elemental content Correlations between restricted organic content and inorganic elemental limits

The Geno/Grinder® and Freezer/Mill®

See how the Geno/Grinder and Freezer/Mill can be used to prepare different sample types in this virtual demo. The Geno/Grinder® is a high-throughput homogenizer that is specifically designed for rapid cell disruption, cell lysis and tissue homogenization through bead beating. This enables fast and efficient extraction of nucleic acids, proteins and other molecules. The Freezer/Mill® is a programmable cryogenic mill specifically designed for grinding and pulverizing tough or temperature sensitive samples. Applications include DNA/RNA or protein extraction from tissue samples or yeast cultures, THC extraction from infused edibles, forensic testing, RoHS/WEEE, volatiles extraction and contamination testing in pharmaceutical products and packaging.
