Gerhardt Crude Fibre ADF / NDF Equipment
Fibretherm Automated Fibre Analysis System
Development of the Gerhardt Fibrebag method was the full automation of the Crude Fibre analysis. As well as automating the chemical additions, rinsing and filtration, increased sample throughput was achieved by increasing the capacity of the carousel to 12.
The Fibretherm system still closely emulates official methods, but allows multiple extractions to be performed automatically. Thus saving time and chemicals.
Samples are weighed into the Fibrebags and a glass spacer introduced to allow free flow of reagent through the bag. The Fibrebags are then placed into the carousel and the carousel then lowered into the beaker.
The beaker is then placed on the ceramic hotplate and the stored programme started. Up to 9 programmes can be stored for different methodologies.
Fibretherm system FT is supplied with beaker and 12 glass spacers drip tray and carousel handle. Compressed air is required to operate the system at a pressure of 4 bar. Fibrebags, reagent storage tanks and compressor must be ordered separately.
FibreBag System (FBS)
This new system of analysis was developed to closely emulate official methods, but allow multiple extractions to be performed in each boiling vessel. Thus saving time and chemicals. A bonus of the FibreBag system was the discovery that filtration became easy and very quick compared to the traditional method. Filtration under vacuum and the problems that often occur have been eliminated. Throughput of tests per hour is increased by a factor of six. Accuracy and precision are also improved.
Samples are weighed into the FibreBags and a glass spacer introduced to allow free flow of reagent through the bag. The FibreBags are then placed into the carousel and the carousel lowered into the reagent in the beaker.
Using the Traditional Fibre digestion systems as a base each FibreBag digestion system FBS is supplied with a powerful single, 4 or 6 place EV hotplate. The relevant number of beakers, condensers, and carousels each holding 6 FibreBags are supplied according to the number of positions. Support rods with sliding beaker clip and condenser holder are also included along with carousel handle and glass spacers for FibreBags. FibreBags must be ordered separately.
