To get reliable analysis data, the sealing process of the sample vials needs to be reproducible. This is difficult to achieve with manual crimpers. Learn more about our range of electronic crimping tools that solve inconsistencies in crimp results.

What sounds like an unequal David - Goliath battle may be the key to a new therapeutic approach in the fight against COVID-19 disease.
2-deoxy-D-glucose is a glucose molecule in which the hydroxyl group in the 2 position has been replaced by hydrogen.
Chloramphenicol (CAP) is a widely used broad spectrum antibiotic in food of animal origin. It is often used as a bacteriostatic antimicrobial agent in honey production.
Its lipophilic backbone interacts with nonpolar hydrocarbon residues of the analytes while the linked hydrophilic groups interact with polar functional groups to provide enhanced retention.
Robotic sample preparation lines as well as some autosamplers are constructed that way that they lift and transport vials with a magnet the size of the vial’s cap. In these cases aluminum crimp or plastic screw caps cannot be used, as these materials won’t react to a magnet. Only metals like steel or tin will do so, however, they will also bear some problems that need to be considered.
