GLF-1 Gelbo Flex tester system with 1CFM Airborne Particle Conter


Honri Airclean Technology Co., Ltd has researched and developped the set of GLF-1 Gelbo Flex Tester System with the instruction of Jinan Quality Supervision and Inspection Center for Medical Devices.

The particle counter for use with this GLF-1 Gelbo Flex Tester System is to ascertain the amount of loose fibres (lint) to shed from non-woven materials in a 30 seconds time period of flexing.

With non-woven textile joining the traditional lines of products such as plastics, paper, textiles etc. for uses in healthcare and hygiene, cleaning, filtration, food packaging and more, cleanliness is an important consideration; therefore, such materials must have a low propensity to lint.

Using IST160.1 and ISO9073-10:2003, Honri has designed the Gelbo Flex Tester System with particle counter (Honri brand) for measuring the linting of non-wovens in the dry state. This test can also be applied to other textile materials.


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


While the sample is being subjected to repetitive twisting and compression cycles on the Gelbo Flex Tester, air is withdrawn from the testing chamber and the particles in the air stream are counted and classified on the particle counter.

Environment of testing

ISO 5 (class 100).

Main parts

Gelbo Flex Tester

Flexing Chamber and Air Collector

CLJ-B330(L) Airborne Particle counter

Laminar flow bench SCW-VS-1300 (optional, it is used to supply ISO 5 clean air)




Introduction of main parts

The Gelbo Flex Tester consists of two 82.8mm dismater 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 per min of 180°rotation over 120mm of stroke toward and away from the fixed mandrel.

The Flexing Chamber and Air Collector measuring 300*300*300mm is made from plexigalss and has removable panels for cleaning. Three panels have two suitable 10mm air vents. An isokinetic intake probe (air collector) is fixed to the centre of the flexing chamber. A purge filter is fitted to the instrument and is used to reduce the amount of airborne dust/lint within the flexing chamber throughout testing.

The particle counter counts and sorts the particles in real time with relevance to sizing from 0.3 to 25.0μm. The counter has a flow rate of 1CFM (28.3LPM), and it can print reports on a built-in thermal printer. Iptional RS232 out put is available.
