Product Information:>hJ4Textile Testing Instruments, Testing Equipment Manufacturer
The Rapid Grease Extraction Apparatus was developed specifically for obtaining the oil content of tops and similar materials sufficiently quickly for the results to be available at the time of processing.hJ4Textile Testing Instruments, Testing Equipment Manufacturer
The principle of extraction is percolation of a solvent through the wool sample in a simple metal tube. The extract, as it drips from the tube, is collected by a light aluminium tray held between two metal rings mounted on a temperature-controlled hot-plate.hJ4Textile Testing Instruments, Testing Equipment Manufacturer

Features:>hJ4Textile Testing Instruments, Testing Equipment Manufacturer
1.The instrument consists of pedestal, extraction tub, weight, plunger, cotton wool plug, tray, and the hot-plate.hJ4Textile Testing Instruments, Testing Equipment Manufacturer
2.The tube should be positioned in the hole in the lower support member of the apparatus, and the plunger boss placed in the hole in the upper support member.hJ4Textile Testing Instruments, Testing Equipment Manufacturer
3.In use the plunger is placed through the boss and down into the tube. The weight is then located on top of the plunger.hJ4Textile Testing Instruments, Testing Equipment Manufacturer

Testing Method:>hJ4Textile Testing Instruments, Testing Equipment Manufacturer
Before starting a series of tests, the hot-plate is allowed to warm up to a suitable temperature (set by the power regulator knob). The correct temperature has been obtained when the solvent evaporates from the dish almost as quickly as fresh solution filters through to replace it. This prevents flooding of the tray and losing oil to the brass ring.hJ4Textile Testing Instruments, Testing Equipment Manufacturer
The temperature must not be too high, however, or the solvent will evaporate violently as the drops of solution hit the hot tray.hJ4Textile Testing Instruments, Testing Equipment Manufacturer
Before each test a pre-weighed aluminium tray is placed on the hot-plate brass ring. The tray location ring is then placed on the tray to secure it and to maintain a good thermal contact with the lower ring. The bottom of the tray must not touch the hot-plate.hJ4Textile Testing Instruments, Testing Equipment Manufacturer
This test method is most suitable for extracting loose wool or combed slivers, but it may also be used for yarn. It is not suitable for fabric unless it is first disintegrated into yarn to facilitate uniform packing in the extraction tube.hJ4Textile Testing Instruments, Testing Equipment Manufacturer
