Significance of Non-Volatile Residue Detection in Purified Water Purified water is a crucial raw material in industries like pharmaceuticals, biotechnology, and electronics manufacturing. Non-volatile residues are non-evaporating substances (like inorganic salts, organic matter, microbial byproducts) that remain after evaporation at a specific temperature (e.g., 105℃). Detecting Non-Volatile Evaporation residues is important for Regulatory Compliance: Meeting limits set by pharmacopoeias (e.g., For " Purified Water in Containers", the Ph. Eur. European Pharmacopoeia has a requirement for "Residue on Evaporation" of ≤0.001%). Process Stability and Risk Control: Accumulation of residues can alter water conductivity and pH, affect process consistency, clog equipment, corrode metal parts, or interfere with reactions. Drug Production Safety: Heavy metals (e.g., lead, mercury) or endotoxins in residues can contaminate drugs, causing allergic reactions or toxicity in...

Labthink C690H Non-Destructive Leak Detector uses a vacuum-based testing method (and also a positive pressure method) to find tiny leaks in different kinds of containers. It's built according to international standards like ASTM F2338 and is particularly useful for checking various packaging in industries like food, pharmaceuticals, daily chemicals, and electronics, such as vials, ampoule, cartridge bottles, infusion bottles and prefilled syringes. How it works It works by placing the sample in a sealed chamber, creating a vacuum, and then using sensors and a fluid dynamics model to calculate the leak rate and the size of the leak based on how fast the pressure drops. It can operate in two modes: Vacuum mode: It creates a negative pressure (vacuum) around the sample and measures how quickly the pressure inside the sample drops. This works well for most packaging types because the vacuum helps to "pull" out any leaks, making them easier to detect. ...

OLED is extremely sensitivity to water vapor, even microscopic amounts of moisture can lead to rapid degradation, causing unsightly dark spots, short circuits, and significantly shortening the display's lifespan. This is why the OLED Display Water Vapor Transmission Rate Test is so important. The impact of WVTR testing extends far beyond mere measurement; it directly influences the quality, longevity, and market viability of OLED products. Ensuring OLED Device Lifespan and Performance: OLED components are extremely vulnerable to moisture. Water vapor ingress causes metal electrodes to oxidize and organic layers to degrade, leading to critical issues like dark spots and short circuits.To achieve an OLED device lifespan of at least 10,000 hours, the industry recognizes a critical WVTR target of 1 x 10 ⁻⁶ g/(m ²· day). This tester precisely measures and verifies that encapsulation materials meet this stringent requirement. Optimizing Materials and Processes: By testing the ...

The rapid growth of the solar (photovoltaic, PV) industry is driving demand for advanced packaging materials for solar modules. This has led to the development of new materials, notably EPE film .   Photovoltaic EPE film   The New TSHPTA 082-2024 Standard EPE film is a transparent, co-extruded multi-layer film specifically designed for solar panel encapsulation. It combines the benefits of two common polymers EVA and POE. This structure offers a balance of high adhesion, excellent barrier properties, strong weather resistance, and cost-effectiveness. To support the widespread use of EPE film, a new product standard, TSHPTA 082-2024 : "Co-extruded EPE film for photovoltaic module encapsulation," has been officially implemented. This standard was developed by a team of experts from various fields, including new energy, new materials, testing instrument development, and research institutions. Labthink , a company...

Military operations and strategic reserves demand food with a long shelf life. This extended durability relies heavily on superior packaging that can protect food quality under diverse conditions. This article utilizes the Labthink C330H Water Vapor TransmissionRate Test System to evaluate a military food packaging material, including the test principle, process, instrument parameters, and scope of application, offers a reference for monitoring and selecting effective moisture barrier packaging solutions. During military operations or special missions, food is an indispensable supply for maintaining troop vitality and enhancing combat effectiveness. Considering military strategy and material reserves, military food generally has a shelf life of more than 2 years, which requires its packaging materials to have excellent performance to ensure the food remains in good quality during storage. Furthermore, the uncertainty of supply and environmental conditions places higher demands on pack...

Sachet packaging, along with many other flexible packaging formats, relies on robust heat sealing for secure product containment. The heat seal strength test is vital for guaranteeing these seals are strong enough to protect the product effectively throughout its journey, from manufacturing to consumer use. This essential test involves preparing a sealed sachet sample and precisely measuring the force required to peel or break the seal. This critical data empowers manufacturers to: Ensure Seal Integrity: Consistently verify that seals will not fail prematurely, thereby preserving product quality and freshness. Optimize Sealing Parameters: Precisely identify the ideal heat, pressure, and dwell time settings for creating consistently strong and reliable seals. Reduce Production Waste: Significantly minimize the occurrence of leaks, bursts, or otherwise compromised sachets, leading to improved efficiency and reduced material loss. Instruments ...

Food contact materials, such as plastics, rubber, ceramics, and metals, can release chemical substances into food during contact, posing potential food safety risks. Overall Migration Limit (OML) testing is a crucial indicator for assessing the safety of these materials. Its significance is highlighted in several key areas: Protecting Consumer Health OML testing quantifies the total amount of non-volatile substances that migrate from the material into food. This helps prevent health risks such as chronic poisoning, cancer, and birth defects that could result from excessive levels of harmful substances (e.g., plasticizers, heavy metals, monomer residues). For instance, if phthalate plasticizers from plastics migrate into food, they could disrupt the human endocrine system. Ensuring Regulatory Compliance Major global markets have established strict OML limits for food contact materials: Ÿ    European Union (EU): According to Framework Regulation (EC) No 1935/2004 an...
