Hydrolysis SystemsHydrothermAutomatic Hydrolysis SystemFor sample preparation in the traditional fat analysisacc. to Weibull-Stoldt.In comparison to the classic Soxhlet-method, theHydrotherm offers various advantages. Up to 6samples (3 modules with 2 positions for extraction)can be extracted and filtered simultaneously orindependently of each other in a closed and monitoredprocess. Thanks to the intelligent constructionof the filter, almost any kind of samples with an initialsample weight of up to 10 g can be analysed.The filters are compatible with traditional Soxhletdevices,Soxtherm and other extraction systems.Modern operation softwareHydrotherm Manager is the controlling software whichsupports the user in operating and controlling the unit. Theprogramme is extremely user friendly and offers numeroussettings. Furthermore, methods can be developed, the pumpscan be calibrated, the entire analysis is monitored. Errormessages are noted by the software and whenever a problemoccurs, the analysis can be aborted. Thus the presence of ahuman operator is reduced to a minimum.Manual handling is kept to a minimum, thus offeringtremendous savings especially for labs with ahigh sample throughput.Fat determination usingHydrotherm e.g.:Cereal and cereal productsMilk and dairy productsMeat and meat productsChocolate and cocoaproductsOil and oil seedsand many more8 - 9Hydrotherm 6-placeFurther product informationis available from our productbrochure Hydrotherm orfrom the Gerhardt representativein your country.

FibreBag-SystemsFibreBagCrude Fibre-, ADF- and NDF-DeterminationThe FibreBag method developed by C. Gerhardtrevolutionized the classical determination acc. toWender, van Soest and others and reduces thehandling to a minimum. The boiling process iscontrolled and the unique, highly precise filtrationtissue of the FibreBags ensures optimal results. Thepossibilities of saving costs are especially high forlaboratories with high sample throughput. Not onlywill they save precious bench space in the lab, butthey will also reduce the consumption of chemicalsdramatically.FibreBag and glass spacerFibretherm FT12 - automaticBased on the established Gerhardt FibreBag Method, thenew Fibretherm offers the fully automated processing of thetedious boiling and filtration steps for crude fibre-, ADF- andNDF-determinations. As up to 12 samples can be digested andfiltrated simultaneously, tremendous savings in lab space andconsumption of chemicals are made.Fibretherm offers many advantages in comparison tothe standard method:Automation of procedureSimultaneous analysis of up to 12 samplesStorage of up to 9 methodsQuick and safe filtrationShort heating up timeSaves chemicals thus saves as well the costs for wastedisposalMonitors cooling water and energyEasy cleaning and save operationLow blank values due to almost complete incinerationFibreBag - manualFor labs with low sample throughput, Gerhardt offersthree simple and economic systems.
