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 Introduction The GBB-A3 Lid Film Heat Sealer can accurately determine heat seal performance parameters (including heat seal temperature, time, and pressure) for lid films used in food and pharmaceutical packaging, such as those for jelly cups, yogurt cups, coffee capsules, instant noodle buckets, meal boxes, and medical blister packs. Since heat seal performance varies across different materials, measuring these parameters allows for precise determination of optimal heat seal conditions. Testing Principle Install appropriate fixtures on the instrument’s lower pallet and place the sample on the fixture. Set the desired heat seal temperature, time, and pressure, then start the instrument with one click—the upper fixture will descend to seal the sample. In manual mode, pressing the foot switch once activates the sealing knife, and the heat seal duration is determined by the preset time. In automatic mode, the upper and lower sealing knives repeatedly perform heat sealing automatically according to the set time. Executive Standards QB/T 2358-1998, ASTM F 2029, YBB00122003-2015 Technical Parameters Item Specification Temperature Range Room temperature ～ 250℃ Temperature Control Precision ±1℃ Heat Seal Time 0.1s ～ 99.99h Heat Seal Pressure (0~1) MPa Operation Modes Automatic and manual Air Source Compressed air Dimensions 730(L) mm × 400(B) mm × 535(H) mm Weight 45 kg Power 1200 W Power Supply AC 220V, 50Hz   Product Features Pull-out Loading DesignThe lower pallet features a double-layer stacking structure, enabling pull-out loading that keeps operators away from the upper sealing knife, ensuring both convenience and safety. High-Precision Temperature SensorEquipped with a high-precision temperature sensor and PID algorithm for temperature control, achieving a precision of ±1℃, with ultra-high stability and extremely low failure rates. Flexible Testing OptionsFreely switch between manual and automatic testing. The automatic mode saves time with fully automated, repeatable heat sealing; the manual mode includes a compatible foot switch—pressing it once activates the sealing knife, ensuring safe and easy operation. Advanced Pneumatic Drive SystemComposed of a pressure gauge, pressure regulating valve, and cylinder, the system uses compressed air. Pressure is adjusted via the valve to precisely lock air pressure, enabling pneumatic-driven heat seal clamping for efficient operation. Extensive Customization Services Custom fixed fixtures can be made according to samples, and fixtures are interchangeable based on cup sizes. The sealing knife can be upgraded with anti-stick functionality for a better user experience, making it easier to determine optimal heat seal conditions. Customizations for the shape, size, and smoothness of the sealing surface are available to meet diverse research needs.  

The thickness of the film material, an important characteristic of the packaging material, varies and is critical for other properties such as permeability, tensile strength, impact resistance, etc.

Oxygen transmission rate (OTR) is the measurement of the amount of oxygen gas that passes through a substance over a given period. It is mostly carried out on non-porous materials, where the mode of transport is diffusion, but there are a growing number of applications where the transmission rate also depends on flow through apertures of some description.

Product introduction The W303 WVTR tester is designed and produced based on the test principle of weight method (weight reduction) and as per the standards of GB/T 1037 and ASTM E96, etc. It is suitable to measure the water permeability performance of film, sheets, papers, packagings and other related materials in the industries of food, pharmaceutical, medical equipment, daily chemicals, Photovoltaic electronics, etc, providing wide range and high efficiency water vapor transmittance detection for high, medium and low water vapor barrier materials.
