The FOSS Total Fat solution automates and simplifies total fat analysis. Consisting of an extraction unit, a hydrolysis unit and a FOSS single filter system that is common to both units, the FOSS Total Fat solution allows you to perform Acid Hydrolysis and Solvent Extraction with one integrated procedure. The system reduces the potential for human error in total fat analysis while reducing costs and improving overall sample throughput.
Simplified process
improves safety and reduces costs
Consisting of an extraction unit, a hydrolysis unit and a single filter  that  is  common  to  both  units,  the  SoxtecTM   8000  and HydrotecTM   8000  solution  allows  you  to  perform  total  fat analysis  with  one  integrated  process.  The  unique,  patented Hydrocap filter avoids sample transfer so reducing the risk of human error. Laboratory costs are dramatically reduced and higher  sample  throughput  improves  cost  effectiveness.  The hydrocap holder enables traceability by keeping and remaining the individual samples in the holder througout the weighing, hydrolysing and drying, all the way to docking the samples in the extraction unit.
The compact hydrolysis unit is about the size of a small food processor, saving valuable space in the laboratory. And a com- prehensive range of handling tools make routine operations safer and more efficient.
Faster
The hydrolysis stage is often considered the bottleneck in total fat  analysis  because  a  limited  flow  of  samples  here  means limited flow in the subsequent extraction phase. The unique Hydrocap single filter improves throughput by containing the sample all the way through from the initial weighing, through hydrolysis  to  final  extraction.  The  filter  fits  into  an  easy-to- handle holder. This is placed in a 12 positions Hydrolysis system and then transferred directly to the extraction unit which has up to 12 positions.
The virtually seamless sample transfer from hydrolysis to extrac- tion improves speed by reducing manual handling and avoids potential  human  error  while  the  high  capacity  throughput improves your overall response time.
Soxtec integrated total fat analysis
The  FOSS  total  fat  solution  allows  you  to  perform  total  fat analysis with one integrated process.
There are three main elements to the solution: the Hydrotec™ 8000 hydrolysis unit, the Soxtec™ 8000 extraction unit and the Hydrocap that works in both. The extraction unit has an external controller and a broad range of accessories.
The HydrotecTM 8000 unit performs automated acid hydrolysis of samples to break up bonds between fat and other compo- nents. Traditionally, hydrolysis units have a capacity of up to six samples and, at this capacity, instruments take up a lot of bench space in the laboratory. The Hydrotec™ 8000 changes that paradigm.  It has a twelve place sample holder with a fold- ing action so that samples to fit neatly into the hydrolysis unit.
Chemicals are added and removed by pump, improving safety and reducing the risk of human error.
After  hydrolysis  the  samples  and  Hydrocaps  are  dried  and placed  in  the  specially  designed  tool  for  transferring  to  the extraction unit in sets of six hydrolysed samples.
The filter is made of an inert material that retains the fat during hydrolysis, but releases it during extraction.
The SoxtecTM  8000 extraction unit is  a  fully  automated system for fast and safe determinations of extractable matter. For  total  fat  analysis,  the  Hydrocap  filter  is  transferred  from the hydrolysis unit to the extraction unit which then performs the four extraction steps boiling, rinsing, solvent recovery and auto shut down, fully unattended. Just load and start.
Closed Solvent addition
Some users simply add solvent to the extraction cups before starting the extraction. When used with an external dispenser1, a solvent dispensing selector aligns to individual sample posi- tions  by  simply  turning  the  dial  to  the  appropriate  position thus avoiding solvent handling. Compared to classical Soxhlet, the  Soxtec  system  uses  significantly  less  solvent.  Solvent  is recovered automatically.
The standard model has six hotplate positions, but users have the option to extend to 12. All positions can be individually temperature controlled. An automatic shutdown feature per- mits out-of-hours operations allowing for high throughput of up to 14 batches or 284 samples per day.
