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.

The tear tester (elemendorf method) tests the tear resistance of paper, film, PVC, polyolefin, polyester, composite film, sheet, non-woven fabric, textile, paper, and board, etc. It is controlled by computer automatically and can be tested independently.

Introduction The N560 2.0 Gas Transmission Rate Tester is a high-precision laboratory testing equipment integrating machinery, electronics and software. It is suitable for the gas barrier property test of plastic films, composite films, sheets, metal foils and other sheet materials, as well as the gas transmission rate test of packaging containers such as bottles, bags, cans and boxes made of plastics, rubber, paper and other multi-type materials.  

Accelerated weathering tests are performed on materials by simulating ultraviolet radiation and condensation in natural sunlight to obtain results on material weathering resistance. It can simulate environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation, and darkness in natural climates. By reproducing these conditions, it can be combined into a cycle and allowed to automatically complete the cycle as required.

Product Brief The N600P Paper & Paperboard Air Permeability Tester is custom-developed to align with standards like GB/T 458-2008 and ISO 5636. It adopts the differential pressure method as its core testing principle, and innovatively integrates three industry-common testing approaches (Gurley, Schopper, and Bendtsen) into a single device.   This tester is applicable to air permeability detection of various paper and paperboard materials, and can measure key indicators including: material air permeability, air resistance, gas transmission rate, and total gas transmission volume. Testing Principle Gurley Method   Under a constant differential pressure of 1.23 kPa, measure the time required for 100 mL of gas to pass through the sample. Schopper Method   Select a suitable test duration under a constant differential pressure (1.00 kPa±0.01 kPa or 2.50±0.01 kPa), and calculate the gas flow rate through the sample by measuring the gas volume. Bendtsen Method   After clamping the sample for 5 seconds under a constant differential pressure of 1.47 kPa, test the gas flow rate through the surface of the sample.

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.
