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℃. Core Advantages Dual‑mode operation: boiling disinfection & counter‑pressure pressure sterilization Ultra‑fast 3‑minute counter‑pressure cooling to avoid flexible pouch deformation Heater overload protection & buzzer alarm when sterilization cycle completes Multiple chamber volume options:35L‑50L‑75L‑100L for different test throughput Mechanical program control, easy operation for laboratory staff Technical Parameters Item Specifications Max Working Pressure 0.22 MPa (30 Psi) Max Working Temperature 135℃ Sterilization Temperature Selection 101‑135℃ Boiling Temperature Selection ≤100℃ Timer Range 1‑60 min Effective Chamber Volume 35L, 50L, 75L, 100L Power / Power Supply 2.5 KW / AC220V, 50Hz; 3 KW / AC220V, 50Hz; 4.5 KW / AC220V, 50Hz Overall Dimension 570×550×970 mm(35L);590×590×1110 mm(50L);650×630×1150 mm(75L);680×650×1220 mm(100L) Gross / Net Weight 56/42 kg(35L); 68/50 kg(50L); 90/70 kg(75L); 105/85 kg(100L) Application Scenarios Widely adopted in food R&D laboratories, packaging manufacturers and quality inspection institutes for sterilization and thermal‑resistance assessment of flexible food packaging materials.

AUTO GBM‑L2 Dual‑Pressure Micro‑Leak Seal Tester: Micro‑Leakage Detection for Pharmaceutical & Food Packaging GBPI AUTO GBM‑L2 Dual‑Pressure Micro‑Leak Seal Tester for Packaging Micro‑Leak Detection Product Introduction AUTO GBM‑L2 Dual‑Pressure Methods Vacuum Decay Leak Detection Tester adopts the test principle of vacuum decay method/pressure decay to detect micro‑leakage of finished packaging. It can be applied to packaging systems composed of vials, ampoules, pre‑filled syringes, eye drop bottles, HDPE bottles, infusion bottles/bags and other pharmaceutical packaging, food packaging, and chemical industry packaging. Testing Principle The host is connected to a sealed test chamber customized according to the sample. When performing the vacuum decay method test, the instrument evacuates the test chamber, and a pressure difference is formed inside and outside the sample. Under the action of the pressure, the gas/liquid in the sample enters the test chamber through the leak hole. The main engine uses the absolute pressure sensor and the differential pressure sensor to monitor the pressure change in the chamber to judge whether the sample leaks. When performing the pressure decay method test, the instrument fills the test chamber with a predetermined air pressure, and the gas in the test chamber enters the sample through the leak hole. The host uses absolute pressure sensors and differential pressure sensors to monitor the pressure changes in the chamber to determine whether the sample is leaking. Executive Standards ASTM F2338‑2009(2013), YY‑T 0681.18‑2020, USP<1207.2>, ASTM F2095, supporting leakage verification for global pharmaceutical and food packaging regulatory requirements.
