An apparently unused B&uchi E-816 Sox extraction system, B&uchi order number 047581, enables the simultaneous fat analysis of six food and feed samples at the push of a button. As an automatic Soxhlet device, the E-816 SOX complies with all officially recognized methods. The E-816 HE (hot extraction) device offers an alternative for quick routine fat analysis. The system offers time and cost savings by being able to process up to six samples simultaneously with just the push of a button, reducing solvent consumption and therefore operating costs, accelerating heating through a ceramic plate and individual heating zones, and optimal reproducibility through precise time and cycle control guaranteed. It is also user-friendly thanks to easy method selection for the entire process, including rinsing and drying, intelligent heating power selection with a solvent library and unattended operation by monitoring cycles and/or time. Safety and standard compliance are ensured by minimizing solvent emissions using the Z-seal system and high-performance cooler, optimal recycling through the cooled solvent container (recovery > 90%), protection against burns through efficient shielding and heating regulation, and compliance of the SOX configuration with the Original Soxhlet apparatus ensured Labprocure is responsible for this device.
