Polyester Reference Material

Test Principle Firstly submerge the specimen in the water in the vacuum chamber, and then evacuate the vacuum chamber to form differential pressure between the inside and outside of specimen. The seal property can be obtained by observing the steady progression of bubbles from the specimen or observing how the specimen expands and restores to its original shape after vacuum release.

Folding Endurance Tester mainly test the folding endurance on paper, cardboard and other flaky materials, but the thickness less than 1.25mm. Its main technical indexes and performance parameters accord with related national standards.

The Adhesive Tape Roller GX-Y2 is suitable for plastic film and cellophane decorative prints (including composite film prints) produced by gravure printing process. It is also used to test the adhesion state of the surface layer formed by vacuum coating, surface coating, compounding and other related processes.

One test chamber water vapor permeability analyzer using weight reduction method is to test the water vapor transmission rate (WVTR) of films or sheets materials.

GBPI Gas Permeability Tester N530 demonstrate how to test gas volumn pass through your packaging material

Water vapor permeability analyzer is used to test water vapor transmission rate (WVTR) of films or sheets materials for flexible packaging.

Application It is to test the filtering efficiency of particulate protective masks and medical masks and to determine the resistance of ordinary fabrics and medical protective masks to the constant flow of airflow.

Laboratory Glass Package Tester for Ampoule, injection bottle, infusion bottle, oral medicine bottle. Thickness testing, Burst, testing, Pressure Resistance testing, and Thermal Testing for Medical/Pharma Packages. 20+ Years Test Experience.

Spectrophotometer ST50 is a spectrophotometer developed by GBPI series core technology, using built-in photodiode array (double 20 groups) sensors, imported whiteboard, while taking into account the measurement speed and convenience of operation. The repeatability delta E* AB of ST50 spectrophotometer is easily controlled within 0.03, and the Inter-instrument error delta E* AB is controlled within 0.2, to make the measurement more accurate. And the test data can be used for accurate color analysis and transmission in the laboratory. Application  Spectrophotometer ST50 is equipped with one customized measuring aperture, accurate color measurement and stable performance. It is used for accurate color measurement and quality control in plastic electronics, paint ink, textile and garment printing and dyeing, printing, ceramics and other industries, and can be used for fluorescent sample measurement.   Features  1. Large area photodiode array (dual 20 arrays) sensor  A larger area of double 20 array sensor, strong light saturation, weak light sensitivity and a wider spectrum response range, to ensure the instrument measurement speed, accuracy, stability and consistency, independent core technology, and international standards of the same platform, to achieve complete compatibility. 1. Adopt D/8 structure and SCI/SCE mode  Spectrophotometer ST50 uses a widely international use D/8 optical structure, SCI/SCE (Specular Component Included/Specular Component Excluded) synthesis technology, support SCI+SCE at the same time fast measurement, test time about 1.5 seconds.  2. Combination of full spectrum LED light source and UV light source The use of 400-700nm full spectrum LED light source ensures sufficient spectral distribution in the visible light range, avoiding the spectral loss of specific bands, strong light will not be saturated, weak light is more sensitive, and fluorescence samples can be easily measured. 4. Camera positioning can clearly observe the measured area  The ST50 spectrophotometer has built-in camera. Through the real-time scene-taking of the camera, it can accurately determine whether the measured part of the object is the target center, which improves the measurement efficiency and accuracy.

Product Description The LC-2 Sample Cutter is used for cutting samples of various plastic films, paper and other materials prior to stretching, peeling and heat sealing tests. It is easy and efficient to operate and can accurately cut samples of standard required sizes.   Features Meets the sample making requirements for Type 2 specimens of standard GB/T 1040.3. Using imported tungsten steel finely ground special blades, sharp and durable, with hardness up to 92 HRA. Accurate sample size, no damage, smooth and burr-free edges. Spring tensioned for easy sample fixing and smooth sample cutting. The ability to cut up to 12 samples in a single pass allows for efficient production of large batches of samples. Safety protection, the outer layer of the blade is covered with an aricotta stopper so that the blade does not come into direct contact with it. Different sample widths can be ordered to suit the requirements of each customer.
