Dry fallen wadding tester G275

The G275 dry fallen wadding tester evaluates shedding performance of medical  nonwovens and textiles under dry conditions by subjecting samples to torsion and  compression. Air drawn during twisting is analyzed with a laser dust particle  counter to count and classify particles. It features a high-resolution touch  screen, monitors 8 particle size channels, and stores extensive data, useful for  air quality and filter tests.

Application

G275 dry fallen wadding tester, is mainly used for the evaluation of shedding  of raw materials used in surgical orders, surgical gowns, and clean clothes.

It is applicable to the performance verification of new products, quality  control of the production department, and the of material properties for the  third-party testing organization, the product performance verification  laboratory, and the quality and technical supervisiondepartment, etc.

Standards

YY/T 5056.6 Surgical sheets, surgical gowns and cleansing suits for patients,  medical staff and equipment - Part 4: Dry fallen wadding test method;

ISO 9073.10 Test method for textiles and nonwovens - Part 10: lint and other  granules produced in a dry state;

EN 13795-2-2004 Surgical covers, long coats and non-contaminated suits for  patients, medical staff and medical equipment, part 2: test methods

Features

Smart touch screen control panel

Microcomputer control system, more efficient and reliable, programmable  7-inch color LCD touch screen, to achieve control, detection, calculation, data  display, printing and other functions.

Transparent anti-static test box

The test box of the instrument is made of special material which is  transparent and anti static. The test will not have precision adsorption, and it  can also observe the operation of the instrument in real time, which is safe and  reliable.

Compact structural design

The special structural design of the instrument ensures that the test device  producing combined action of torsion, compression and resetting to test pieces,  fully meets the requirements of the standard. The test data has good  repeatability and accurate data.

Parameters

Accessoriess

A brief description of the accessories for the atomization tester is as  follows:

Core Components: Fogging cup (for holding the sample), cooling tray/plate  (providing a cooling environment), glass plate (for gloss method testing) or  aluminum foil (for gravimetric method testing).

Measuring Instruments: Gloss meter (for measuring gloss changes), electronic  balance (high precision, for weighing changes in aluminum foil weight).

Auxiliary Accessories: Sample clamping ring (for fixing the sample), beaker  (for holding the medium), sealing ring (to ensure airtightness), sampler (for  taking and placing samples).

Calibration Supplies: Calibration plate (for calibrating the measuring  instrument), standard samples (for verifying test performance).

Test Procedures

The operation method of the atomization tester includes the following  steps:

Sample Preparation: Pre-treat the sample according to the testing standards,  such as cleaning, drying, and aging under specific conditions.

Instrument Settings: Adjust the instrument's temperature, humidity, airflow  speed, and other parameters according to the characteristics of the sample and  testing requirements.

Test Execution: Place the sample in the test chamber, start the instrument,  and record the test time and the amount of mist in the mist collection  device.

Data Analysis: Calculate the atomization rate, mist distribution uniformity,  and other indicators based on the test data to evaluate the sample's atomization  performance.

When operating the atomization tester, users should pay attention to the  following:

Ensure the sample is clean and dry before testing.

Adjust the instrument's temperature, humidity, airflow speed, and other  parameters to simulate the temperature and humidity conditions in actual  application scenarios.

Record the test time and the amount of mist in the mist collection  device.

Calculate the atomization rate, mist distribution uniformity, and other  indicators based on the test data to evaluate the sample's atomization  performance.
