Tensile Tester QTens-Series

Tensile Testers Overview

Qualitest QTens benchtop tensile testers measure force, stretch, and bond performance on thin materials. Built with single vertical column frames, high-precision load cells, and digital controls, these machines deliver reliable numbers for plastic films, flexible packaging, paper, and adhesive tapes. Operators can run cycles directly from the front panel while seated comfortably at a workbench, watching test curves appear in real time without needing an external PC connected.

The series includes two distinct configurations. The entry-level QTens-I covers standard tension, peel, tear, and seal strength up to 500 N. The QTens-II expands capacity up to 1500 N with a servo motor and ball-screw mechanism, adding puncture, compression, shear, and specialized pharmaceutical package evaluations. Both setups feature automatic returns, overload shutoffs, and built-in micro-printers so you can walk away with printed batch records immediately.

Compliance & Standards

Ensuring your material testing satisfies international quality benchmarks is straightforward with this benchtop tensile testing machine line. The hardware and software align with globally recognized testing procedures from ASTM International, the International Organization for Standardization (ISO), and Japanese Industrial Standards (JIS):

• ASTM D882: Verifies tensile properties of thin plastic sheeting under 1 mm in thickness.
• ASTM D1938 and ASTM D828: Regulates tear propagation resistance of plastic film along with tensile properties of paper and cardboard.
• ASTM D3330: Measures peel adhesion for pressure-sensitive tapes at standardized pull angles.
• ASTM F88 and ASTM F904: Governs seal strength in flexible barrier materials and bond separation for laminated composites.
• ASTM E4: Specifies calibration and force verification for universal testing equipment.
• ISO 37: Establishes international tensile stress-strain determinations for rubbers and thermoplastic elastomers.
• JIS P8113: Provides regional compliance for tensile testing across paper and board.
• GMP Appendix "Computerized System": Both instruments feature administrative access tiers, user tracking, and secure audit trails to protect raw inspection records in pharmaceutical production settings.

Key Features

• Force Capacity from 300 N to 1500 N: The QTens-I provides a 0 to 300 N baseline (with an optional 500 N load cell), while the QTens-II begins at 500 N and scales to 1500 N. This wide force span lets your team inspect everything from high-stretch films with 1250% elongation to tough multi-layer barrier laminates on a single tensile test machine.
• Servo Motor and Ball-Screw Drive: In the QTens-II, a dedicated servo motor turns precision ball screws to maintain steady crosshead movement between 0 and 500 mm/min. This mechanical assembly minimizes vibration, supporting a force measurement accuracy within ±0.5% FS.
• High-Accuracy Force Cells: The QTens-I holds a Level 1 accuracy rating within ±0.1% FS with 100 samples per second. This rapid data collection captures fine changes in heat-seal peel lines and tear initiation points without missing subtle peaks.
• Flexible Test Geometry: An operational travel distance of 750 mm (extendable to 1000 mm upon request) and sample widths of 30 mm (customizable to 50 mm) provide plenty of room for stretchy polymers and wide adhesive specimens.
• Standalone Control with Smart Connectivity: Technicians can run either tensile tester completely free of a personal computer using the onboard LCD or color touch display. For broader laboratory data workflows, the systems connect to a laboratory IoT platform, while the QTens-II supports direct LIMS network export.
• Built-in Safety Architecture: Emergency stop buttons, travel limit switches, and automatic overload protection stop the motor immediately if the crosshead moves past acceptable bounds, keeping operators and sensors safe from accidental damage.

Product Applications & Operating Environments

The QTens series is built for indoor quality control laboratories, manufacturing plant inspection rooms, and academic testing departments. The compact footprint fits directly onto standard laboratory workbenches, operating on standard 220 V electrical lines (with 110 V configurations supplied upon request).

Verified Material Applications

• Flexible Packaging and Plastic Films: Measuring tensile yield, elongation break points, and heat-seal strength on mono-oriented films, co-extruded films, retort pouches, and aluminum-plastic laminate food bags.
• Paper, Tissue, and Cardboard: Quantifying dry tensile resistance, surface peel, and tear propagation across paper sheets, kraft wrapping, facial tissues, and rolled stock.
• Adhesive Tapes and Medical Patches: Verifying 180-degree peel values and release liner separation for cellophane tapes, electrical insulating tapes, and adhesive transdermal patches.
• Pharmaceutical Container Systems: On the QTens-II, specialized fixtures evaluate rubber stopper puncture resistance, syringe needle-shield pull-off forces, piston sliding resistance, vial cap removal, and break-off tabs.

Quality teams in food processing facilities, medical device packaging cleanrooms, plastic extrusion operations, and commercial testing institutes rely on these systems to confirm that outbound shipments match technical tolerances before release.
