Gelbo Flex with Particle Counter

Image
The Gelbo Flex Tester with Particle Counter is to measure the amount of loose fibres (lint) shed from non-woven materials in a 30 second time period of flexing. It is important that non-woven textile materials must have a low tendency to lint. The IDM Gelbo Flex Tester with Particle Counter is a fast and accurate instrument for determining the linting of non-woven materials. This test can also be applied to other materials like tissues. The sample is subjected to repetitive twisting and compression cycles, air is withdrawn from the testing chamber and particles in the air stream are counted and classified with the laser particle counter. For exclusive offer: Email now: marketing@idminstruments.com.au Gelbo Flex Tester with Particle Counter consists of two 82.8mm diameter mandrels, one fixed and the other attached to a moveable arm to perform the flexing action. The moveable mandrel twists and compresses the sample at 60 cycles/min of 180° rotation over 120mm of stroke. Flexing Chamb...

Advancements in Foam Porosity Measurement

Image
The first version of IDM Instruments’ Foam Porosity Tester F0016 was designed and released in the 1980s, in accordance with global industry standards, and was used to determine the ease with which air passed through a cellular structure, namely foam, by comparing the relationship between pressure and flow when subjected to different foam samples. It used vacuum chambers with manometers and was controllable via a manual dial to fine tune flow. This version was purely analogue and required fine use of the dial and flow tubes to be able to give accurate test results. Due to the purely analog design, it was difficult to achieve accurate yet repeatable test results. After more design and upgrades, the second version Foam Porosity Tester F0023 was released in late 2001. Once again improving the accuracy of foam porosity testing. This model boasted variable flow ranges, allowing for more ranges of conditions of testing foam porosities. A huge feature of this model was...
