NITRO 1-Station
Hot Tack & Heat Seal Tester

Precision and Productivity

1-Station NITRO Test System

The NITRO is a budget-friendly hot tack and heat seal test system for labs with lower volume testing demands.

The NITRO test  system measures the hot tack and heat seal properties of film used in flexible packaging, bags and pouches. Under the control of Pilot software, NITRO automatically creates and tests heat seals under a programmable range of pressures, temperatures, dwell times and peel rates. The system automatically tabulates and plots statistics such as heat seal strength versus temperature, hot tack strength versus temperature, and averages and standard deviations of force data.

The test instrument follows the test methods described in ASTM F1921, ASTM F2029 and ASTM F88 for hot tack and heat seal testing, and offers capabilities even beyond those standards.

With its cost-saving single station design, easy to use operation, and precision measurement and control system, the NITRO offers tremendous value in affordability, productivity and data precision.

Easy: Load packaging film specimens in one motion

Insert a specimen into each test station with a fast, single-motion action:


No fussing with painful thumbscrews. No struggling with troublesome levers and mechanisms. The ease of specimen loading greatly contributes to repeatable specimen alignment, better data and higher productivity.

Precision hot tack and heat seal data

Precise: Create accurate hot tack, heat seal data

The NITRO test system is engineered using only the finest transducers and control components. The high sensitivity load cell, independent temperature control for upper and lower sealing jaws, high precision seal pressure control, and high accuracy peel motion servo control are integrated into a precision test instrument.

Contributing to the NITRO’s exceptional data quality is the highly repeatable specimen alignment achieved during specimen loading. Alignment repeatability is a result of the easy-to-use, side-entry grips described before.

Analyze and export seal strength data easily

Pilot software gives you powerful data analysis tools. Plot heat seal strength or hot tack strength versus temperature. View average force and standard deviation at each temperature. And analyze other test results too.

Test data can be exported in CSV format for viewing and further analysis using third party spreadsheet software. Once test data is saved, Pilot Viewer software can be used to remotely access and analyze the saved data.

Precision hot tack and heat seal data

Run heat seal and hot tack tests safely

Once a sample is loaded, close the clear guard door and simply hit “Start” in the Pilot user interface. Under control of the Pilot software, NITRO automatically seals the sample, peels it, collects data and displays the results for instant review.

All tests are safely done behind the protective clear guard door. This provides protection against operator harm, as no moving machine parts are exposed during test execution.

Once the sample has been tested, Pilot prompts the operator to open the guard door to remove the sample and then to load the next sample.

Configure and calibrate quickly

The NITRO is easy to calibrate, configure and maintain:

No specialized tools are needed. There’s no need to keep wrenches, extra fasteners, removal handles, and other tools for routine system configuration work

Fast, easy calibration of load cells
