Fat analysis just got smarter

FOSS enhances fat analysis capabilities
Product analysis expert FOSS has launched a total fat analyser that it claims combines convenience and safety and saves on both costs and labour time.

The Denmark-based company described the Soxtec 8000 extraction unit and Hydrotec hydrolysis unit as the first fully automated solution for total fat analysis using its Soxhlet method.

The device consists of an extraction unit, a hydrolysis unit and a single Hydrocap filter that is common to both. The design enables hydolysis and analysis to be performed in one integrated process, said FOSS. Adding a solvent dosage dial has also enabled the firm to improve safety and minimise operator time.

In addition, the unit is designed to be as energy efficient as possible. Smart water cooling only starts when required, self adjusting hotplates ensure optimal heat transfer to extraction cups and the hotplates can be individually switched on and off.

Saved time and labour

The filter system that goes all the way through hydrolysis to final extraction allows users to avoid filter to filter transfer. This saved time and labour and avoided the risk of human error and associated costs, FOSS said. An optional extra six position unit in the extraction phase allows batch handling of up to 12 samples using the same control unit.

Safety features of the device also improved on existing automated Soxhlet solutions, FOSS said. Features such as the enclosed solvent dosage system and effective cooling help to avoid contact with solvents, chemicals or fumes.

The design of the extraction unit also allows use of a broad range of tested solvents, including some that are considered to be unsafe when used with other solutions.

“This is really a reinvention of doing fat analysis for laboratories,"​ said FOSS Laboratories market manager René Fuhlendorff. "For instance, the Hydrocap single filter going all the way through from weighing to hydrolysis and finally to extraction can really make life easier for laboratories and improve their throughput at reduced cost.”
