Desiccants
Desiccants can absorb water and bind it chemically (reversibly or irreversibly) or physically. The main desiccants can be subdivided into four categories:
- non-renewable chemical desiccants
- renewable chemical desiccants
- silica gels
- molecular sieves

Determination of Trichina
Trichina (Trichinella spp.) are small roundworms approximately 1 mm long that live as parasites in the skeletal muscles of mammals, birds and reptiles. They can be transferred to a new host (human or animal) through the consumption of raw meat containing infectious larvae in the muscle tissue. Meat intended for human consumption must be inspected in accordance with Regulation (EU) No. 2075/2005. Carl ROTH offers reagents suitable for this purpose.
