A Secure Seal Tester is a laboratory test equipment employed to assess the seal integrity and leakage resistance of plastic or glass containers such as bottles, jars, etc. It tests whether the cap or closure of the container can resist internal pressure without leaking, making the product safe when it is stored or transported.
The test is done by pressurizing the sealed container using air or water and checking for pressure loss or visible leaks. This tool is commonly applied within the packaging, beverage, pharmaceutical, and food manufacturing industries to ensure packaging quality, avoid contamination, and meet industry standards for safe sealing performance.
A Secure Seal Tester is a quality control tool employed to measure the sealing strength and leak tightness of packaging like PET bottles, jars, and cans. It guarantees that the package is well sealed to avoid leakage, contamination, or carbonation loss. This testing equipment finds widespread application in the beverage, food, and pharmaceutical industries to ensure packaging performance.
The principle of operation of a Secure Seal Tester relies on the pressure decay or pressurization technique. A container in sealed condition is exposed to controlled internal air or gas pressure, and any pressure loss or visible leakage confirms a weak or faulty seal.
The Secure Seal Tester operates by subjecting the sealed container to controlled air or gas pressure within a sealed vessel to test its seal strength. The vessel is placed in water or a sealed chamber, and pressure is applied gradually up to a set point. If there is the presence of air bubbles or a pressure drop, it reflects a leakage or a weak seal. This process assists in detecting faulty closures so that bottles or jars are able to ensure product freshness, avoid contamination, and resist actual conditions of handling and shipping.
Here are the benefits of a secure seal tester explained in detail:
Provides Leak-Proof Packaging
The Secure Seal Tester assists in the detection of any leakage or poor sealing in containers to ensure that products are safe and free from contamination. Through the testing of seal integrity, manufacturers are able to avoid product wastage, leakage during transportation, and customer dissatisfaction, thus achieving regular packaging quality and brand reputation.
Improves Product Shelf Life
By providing an airtight and secure closure, the tester precludes air, moisture, or contaminants from entering. This preserves the freshness, carbonation, and quality of drinks or other perishable products, ultimately leading to the extension of product shelf life and allowing consumers to receive products in the best possible condition.
Facilitates Quality Control and Compliance
The Secure Seal Tester enables companies to meet industry packaging integrity standards. Constant testing guarantees every batch is compliant with regulatory demands and internal quality specifications, preventing recalls or rejections. It enhances quality assurance processes and enhances consumer confidence in product reliability.
Reduces Production Losses
Early detection of seal defects during the manufacturing process reduces wastage of material and saves costs associated with product returns or leakage cases. Through the guarantee of only sealed containers being available at the market, the tester enhances general production efficiency and operational profitability for manufacturers.
Here are the applications of the secure seal tester explained in detail:
Soft Drink Industry
In the soft drink industry, the Secure Seal Tester makes sure bottles of carbonated beverages, juices, or water are tightly sealed to avoid loss of gas or leakage. It checks for cap integrity and closure performance, keeping the product fresh, carbonated, and ensuring consumer satisfaction during storage and transportation.
Food Packaging Industry
The tester is applied to test seal integrity in sauce jars, cans, and containers storing oils or processed foods. It avoids contamination, spoilage, and leakage by ensuring airtight seals, ensuring that manufacturers keep hygiene levels high, and increasing the shelf life of packaged foods is increased.
Pharmaceutical Industry
In the pharmaceuticals industry, the Secure Seal Tester prevents containers of medicine, vials, and bottles from being improperly sealed and exposed to moisture or air entry. The test is important for ensuring drug stability, potency, and sterility so that drugs are safe and effective up to the point of the end user.
Cosmetic and Personal Care Industry
The tester is applied to test the bottle, tube, and jar sealing of creams, lotions, and other cosmetics. It avoids leakage or contamination during transportation and handling, ensuring product quality, appearance, and consumer confidence in the reliability of the brand's packages.

While exact operational details may vary by model, typically:
The container to be tested is sealed and placed in the test chamber of the instrument.
A defined pressure is applied (or vacuum) to the container (or to the chamber around it) to test whether the seal holds.
The instrument monitors pressure (or time/pressure drop) and may provide a pressure-vs-time graph. In the NXG version this graphing feature is explicitly noted.
If a leak or weak seal exists, pressure drops (or gas escapes) and the instrument detects that deviation, indicating failure of seal integrity.
Here are some of the principal features/specs for the NXG model:
Display: HMI touchscreen interface (in the NXG “Next Generation” variant) for easier user operation.
Test/Equipment Range: Up to ~220 psi equipment range / ~175 psi test range (in many models).
Accuracy: Approximately ±2% of full range.
Resolution/Least count: 0.1 psi (for digital gauge) in some models.
Power: Typical 220 V, single phase, 50 Hz.
Pressure units: Changeable (psi, bar, kg/cm², lb/in²) in some versions.
Inner diameter (sample chamber): ~200 mm in some versions.
Materials / construction: Anodized aluminium, stainless steel, high‐tensile plexiglass / safety shield.
Data output / management: USB option for data export, ability to record product ID, test pressure, time, graphical output.
Automatic sample testing / pressure release mechanism (in NXG).
Use on a stable 220 V single‐phase supply (in standard version) at 50 Hz.
Place sample container (bottle, jar) within the machine’s capacity (e.g., internal diameter ~200 mm) and ensure proper sealing/clamping for test.
Set test pressure, time (preset up to e.g., 999 seconds in some models) and units appropriately for your container/closure type.
After test start, monitor status; export data via USB if needed.
Ensure operator safety: many machines include plexiglass safety shields, etc.
The Secure Seal Tester NXG is a laboratory/quality-control instrument designed to measure the seal integrity of bottles, jars or other sealed containers (glass or plastic) — in particular containers used for carbonated beverages, soft drinks, juices and similar products.
The Secure Seal Tester NXG is suitable for:
Carbonated‐beverage bottles (PET, glass) using roll-on crowns, twist crowns, plastic caps.
Non‐carbonated beverage bottles, juice bottles, water bottles.
Pharmaceutical bottles or containers with sealed closures (though specifications may vary).
More broadly, any sealed container where you need to assess leak or seal integrity (within the machine’s size/pressure limits)
