ملف تعريف المنتج • The W416 2.0 Infrared Method Water Vapor Transmission Rate Tester is a high-end precision testing instrument for packaging materials, newly developed and upgraded by Guangzhou Standard International R&D Team in full compliance with the requirements of **GB/T 26253** and **ASTM F1249** standards as well as market demands. • Based on the testing principle of infrared moisture analysis sensors, it provides wide-range, high-efficiency water vapor transmission rate (WVTR) testing for high, medium and low barrier materials. • It is suitable for testing the water vapor transmission performance of films, sheets, papers, packages and other related materials in industries such as food, pharmaceuticals, medical devices, daily chemicals, photovoltaic electronics, etc. • It is an ideal offline or online configuration instrument for manufacturers in the packaging industry to test the barrier performance of packaging materials. Testing Principle The W416 2.0 Water Vapor Transmission Rate Tester adopts the infrared method principle: 1. Fix the pre-treated sample in the middle of the test chamber, dividing the chamber into a high-humidity chamber and a low-humidity chamber. 2. Compressed air flows through the high-humidity chamber, while dry nitrogen (carrier gas) flows through the low-humidity chamber at a constant flow rate. 3. Due to the humidity gradient, water vapor penetrates from the high-humidity chamber to the low-humidity chamber. 4. The water vapor passing through the sample is carried to the infrared sensor by the flowing dry nitrogen. 5. Parameters such as the sample’s water vapor transmission rate are derived from the electrical signal output by the sensor.

Vertical Counter‑Pressure Retort LS‑35L/50L/75L/100L | Dual‑Mode Sterilization for Food Packaging Aseptic Testing LS‑series Vertical Counter‑Pressure Retort for Food Packaging Sterilization & Laboratory Aseptic Validation Product Introduction Reliable dual‑mode counter‑pressure sterilizer tailored for food packaging quality control & lab aseptic evaluation. The vertical counter‑pressure retort is a medium‑small‑size mechanically program‑controlled counter‑pressure sterilization equipment. The sterilizer adopts electric heating mode. Water is directly injected into the sterilizing chamber and heated to generate high‑pressure steam required for sterilization to disinfect articles. After sterilization is completed, external compressed air and water pressure are applied for rapid cooling within 3 minutes, cooling internal articles down to 30‑40℃. Equipped with program control, it supports two operation modes: boiling disinfection and pressure sterilization with rapid cooling. Boiling temperature can be set ≤100℃. The rapid‑cooling pressure sterilization temperature is pre‑selectable within 101℃‑135℃. It is integrated with heater overload protection and buzzer alarm upon sterilization completion. Featuring simple operation and high safety reliability. This unit is suitable for disinfection and sterilization of food packaging, utensils and instruments. It is an ideal device especially for aseptic tests in food research institutions. Working Principle Dual‑sterilization logic enables boiling disinfection & high‑pressure counter‑pressure sterilization, simulating real‑world thermal processing conditions for flexible packaging samples. This equipment is designed with two disinfection & sterilization principles to deliver dual‑function performance for customers. The heater directly heats water to produce pressurized steam. The pressurized steam acts on microorganisms on samples and destroys their structures to realize sterilization. When rapid‑cooling sterilization program starts, 6 liters of tap water is first injected into the chamber. After around 25‑minute heating process, it enters sterilization holding stage with sterilization duration of 35‑40 minutes. When sterilization finishes, 0.24 MPa compressed air and tap‑water pressure are manually fed into the chamber, then half‑open the drain valve to discharge water and implement counter‑pressure cooling for flexible packages and other specimens. Rapid cooling lasts for 3 minutes. Manually cut‑off compressed air and tap‑water supply, and internal articles can be cooled down to 30‑40℃.
