Time：21.10.2025What is the role of a seal testing machine in packaging? Our in-depth analysis explores how seal testers (like Shounuo's SN-MF1/MF2) use the vacuum decay method to prevent leaks, ensure product safety in food & pharma, and protect brand reputation. Discover the critical technology behind packaging quality control. -
Time：20.10.2025In the packaging quality control of food, pharmaceuticals, cosmetics, and electronic products, the packaging material's oxygen barrier properties are a key factor in determining product shelf life and quality. Therefore, choosing an accurate and efficient otr tester (also often called an oxygen permeator or oxygen permeation meter ) is crucial. With numerous brands on the market, this article will review several representative brands in the industry (in no particular order) and introduce Guangzhou Solutia Scientific Instrument Co., Ltd., a domestically produced company whose technical principles are aligned with international standards. -
Time：16.10.2025This article provides an in-depth analysis of the core working principles, mainstream testing methods (gravimetric method and infrared sensor method), key purchasing considerations, and multi-industry applications of the Water Vapor Transmission Rate (WVTR) Tester (also known as Moisture Permeability Tester). It offers a comprehensive WVTR testing solution to ensure the barrier properties and safety of product packaging. -
Time：14.10.2025In the pharmaceutical industry, drug quality and safety are paramount. The performance of packaging materials (pharmaceutical packaging materials) that come into direct contact with drugs directly impacts their stability, effectiveness, and safety. Barrier properties are a key performance indicator for pharmaceutical packaging materials, determining their ability to effectively resist the intrusion of gases like water vapor and oxygen, while preventing the loss of active ingredients. -
Time：29.09.2025In packaging for food, pharmaceuticals, electronics, and medical devices, the oxygen barrier performance of materials directly affects product shelf life, safety, and functionality. The Oxygen Permeability Tester (also known as OTR Tester) is a critical instrument for evaluating this performance, providing key data for material development, quality control, and packaging design. -
Time：28.09.2025Explore the core principles and applications of Gas Transmission Rate Testers (also known as Gas Permeability Testers). Learn how precise measurement of oxygen, carbon dioxide, and other gas transmission rates ensures quality and safety in food, pharmaceutical, and packaging industries. -
Time：27.09.2025Barrier properties are crucial in packaging, food, pharmaceuticals, electronics, and advanced materials. Water vapor transmission rate ( WVTR ) testers (often called moisture permeation meters ) are key instruments for measuring a material's moisture resistance. Many companies are confused when choosing between the two dominant methods: the cupping method and the infrared method. This article will delve into the principles, advantages, and disadvantages of these two technologies to help you make the most informed investment decision. -
Time：25.09.2025Various organic solvents are used in the production process of pharmaceutical packaging materials, such as toluene and xylene in printing inks, and ethyl acetate and acetone in composite processes. Gas chromatography, with its high separation efficiency and high sensitivity, can accurately detect extremely low levels of residual solvents, promptly identifying these invisible safety hazards. -
Time：17.09.2025Thermal conductivity detector (TCD) is a key component of gas chromatography system, which is a detector for measuring gas thermal conductivity. In short, its working principle is as follows: TCD has heating wires inside, and when the sample gas mixed with the carrier gas flows through these heating wires, the heat transfer of the heating wires will change according to the thermal conductivity of the sample gas. -
Time：17.09.2025In the field of material testing, electronic tensile testing machines play a crucial role, as these precision machines are designed to measure the tensile strength and other mechanical properties of various materials. The control system is the brain of the machine, responsible for regulating the movement of the crossbeam, applying loads, and collecting data. It consists of various components such as sensors, actuators, and control units. Sensors measure parameters such as load, displacement, and strain, while actuators are responsible for moving the crossbeam and applying loads. The control unit processes data from sensors and sends commands to actuators to ensure the accuracy and precision of testing.
