• Oil and oilseeds
• Fruits
• Fat in feed
• Lipids in egg and egg products
• Sample Preparation with Soxtherm

Soxtherm is a very precise instrument when it comes to the determination of the pollution of e.g. soil or water. The data obtained can then be used to make fast environmental decisions.

• Mineral oil in rocks
• Oil and lubricants
• Pesticides
• Phenoles (PCB)
• Dioxine
• EOX - Extractable organic halides
• Plasticisers and additives in plastics and rubber
• Fibre and textile coatings
• Explosives in residual waste
• Coatings of fertilizers
• PAH - Poly aromatic hydrocarbons

PC-Software for Rapid extraction
You can  individually control and monitor up to 4 Soxtherm extraction units type S4 using a PC. All functions, which are already well known from the controller Multistat, are integrated into the program. Furthermore, multiple documentation - and logging options, like e.g. the sample name, program and recognition of the user are offered as well.
With the introduction of the Soxtherm-Manager, Gerhardt now offers an efficient software, which meets all the demands of a modern laboratory management.

• Control of up to 4 Soxtherm basic units
• Monitoring of the Soxtherm basic units
• Programming and storage of the extraction programs
• Logging and documentation of all relevant data
• Diagnosis function for an ideal extraction process
• Concise arrangement of all relevant status displays in separate windows facilitates the best possible supervision 
• Clearly structured program windows
• Each Soxtherm unit has a program window and a status window. At any given time, the user has a perfect overview of all functions andprograms in use. Up to 4 Soxtherm units are displayed at one screen.

Traditional extraction systems Extraction system for extractions according to Soxhlet, Twisselmann and other techniques. If a fully automated rapid extraction process is required or if highly flammable solvents are used please ask for or take a look at Soxtherm. Extraction Heating Unit Serial heating unit EV 14 or EV 16 for 4 or 6 extractions for flasks of 250 - 500 ml using the classical Soxhlet method. Supplied with top moulds, air bath inserts, support rods (600 mm x 12 mm) and power cord. Not included are cooling water feed pipe, Soxhlet glass parts, and holder.

Fibretherm - Crude fibre / ADF / NDF Automated Crude Fibre Determination Based on the established Gerhardt FibreBag Method, the new Fibretherm offers the fully automated processing of the tedious boiling and filtration steps for the crude fibre-, ADF- and NDF-determination. Fibretherm has many advantages compared to the standard method. Up to 12 samples can be digested and filtrated simultaneously, which saves precious bench space as well as chemicals. The savings are especially significantfor labs with a high sample throughput. The procedure with controlled boiling steps as well as the unique, highly precise filtration mesh of the FibreBags ensure highly precise results. The entire process takes place in a closed system.

FibreBag-Method
Up to 12 samples are each weighted into a Fibre Bag. Just like in the traditional method, the required boiling times and filtration steps are done for all samples simultaneously. When determining the crude fibre content, the non soluble contents as sulfuric acid and caustic potash solution remain in the Fibre Bag. The residue is dried, weighted and then incincerated. The difference between the ash content and the non-diluted residue in relation to the initial sample weight, is the crude fibre content. When doing an ADF- and NDF-determination, the sample is treated with the respective detergents, the remaining substances of the cell structure are specified and determined according to this method as well. Also the calculation is done identically to the crude fibre determination.Since all analyses are conventional methods, it is very important to observe the respective times for the boiling procedures as well as observing the weighing procedures as exactly as possible.

Save time:

• Simultaneous analysis of up to 12 samples
• Quick and safe filtration
• Short heating up time

Ergonomic features:

• Small footprint - saves bench space
• Easy cleaning
• Safe operation
• Storage of up to 10 methods
• Use of inert materials - prevents corrosion

Reduce the costs:

• Automation of procedure
• Saves chemicals thus saves as well the costs forwaste disposal
• Monitors cooling water and energy

Optimizes the quality of the analysis:

• Automated reproducible conditions of analysis
• Constant filtration quality of FibreBags
• Low blank values due to almost complete incineration

FibreBag®/crude fibre /Hydrolysis FibreBag Systems for crude fibre-, ADF- and NDF-determination acc. to LEPPER, VAN SOEST, WEENDER a.o. The introduction of the revolutionary FibreBag System by Gerhardt means that the tedious and time-consuming stages usually associated with this determination process like e.g. Weender, van Soest and others, can be reduced to a minimum. Space as well as the consumption of energy and chemicals is reduced to a sixth of the traditional methods. At the same time the conformity to the methods is maintained.Gerhardt offers 3 systems for a special package price. For low sample throughput we recommend the basic pack for up to 6 samples simultaneously. For high sample throughput we recommend the 24-place or the 36-place system, with serial heating plates. All system components can also be ordered individually
