Gelbo Flex Tester System is a microprocessor controlled system, with a user controllable pre-set method programmed for ASTM F392. This makes the Gelbo Flex Tester System both versatile and very easy to use, with only minimal user training needing.

Principal of Gelbo Flex Tester With Particle Counter:
While the sample is being subjected to repetitive twisting and compression cycles on the Gelbo Flex Tester System, air is withdrawn from the testing chamber and the particles in the air stream are counted and classified on the particle counter.

Application:
Experiments of disposable or reuseable surgical bedsheet, surgical clothes and clean clothes for patients clinical staff and equipments.

Test principle:
The sample in the test chamber experiences a comprehensive effect of torsion and compression. During the process of torsion, the air is drawn from the chamber and the particles in the air are counted and classified using a laser dust particle counter.

Basic Structure:
1. Dry lint generator
1) Torsion device: to exert comprehensive force of torsion, compression and recovery
2) Torsion chamber (electrostatic resistance) : an organic glass body with electrostatic resistance which covers the torsion device
3) Air sampler: fixed on a specific location in the torsion chamber. The sample port has a certain shape.
2. Laser dust particle counter
Count and classify the particles in the sampled air.
