Lloyd LS5 Single-Column Universal Testing Machine

Overview

The Lloyd LS5 Single-Column Universal Testing Machine is an entry-level electromechanical materials testing system engineered for precision, repeatability, and operational simplicity in quality control, R&D, and production environments. It operates on a servo-controlled DC motor drive architecture with closed-loop displacement and load feedback, enabling accurate force-displacement characterization across tensile, compressive, flexural, peel, tear, friction, insertion/extraction, and creep/relaxation test modes. Designed to meet the mechanical testing demands of polymers, elastomers, composites, thin metals, adhesives, medical devices, packaging, and consumer goods, the LS5 delivers traceable, standards-aligned performance up to 5 kN — making it suitable for both routine compliance verification and exploratory material behavior analysis.

Key Features

• Single-column rigid frame with high-stiffness aluminum extrusion construction and precision-ground lead screws for minimal deflection and long-term dimensional stability
• Removable YLC-series load cells calibrated to ±0.5% of reading across full scale; interchangeable for optimal resolution at low or high force ranges
• Integrated control console featuring backlit LCD display, tactile membrane keypad, and context-sensitive on-screen prompts for intuitive setup without PC dependency
• Real-time data acquisition at 8 kHz sampling rate — sufficient to capture transient events such as yield onset, fracture initiation, or dynamic peak forces
• Onboard memory stores up to 600 complete test records including raw load/displacement traces, statistical summaries, and pass/fail flags
• 10 user-programmable test setups with customizable speed profiles, trigger conditions, and auto-stop criteria — ideal for multi-step protocols or batch testing
• Multi-language UI (English, German, French, Spanish, Chinese, Japanese) and dual-unit support (N/lbf, mm/in, MPa/psi) for global lab compatibility

Sample Compatibility & Compliance

The LS5 accommodates a broad spectrum of specimen geometries via its modular grip and fixture system — including wedge-action tensile grips, compression platens, bend fixtures, pneumatic clamps, and custom-engineered adapters for medical tubing, blister packs, or suture anchors. All mechanical components comply with ISO 7500-1 Class 1 accuracy requirements for static force measurement systems. The instrument supports full traceability per ISO/IEC 17025:2017 and aligns with critical regulatory frameworks including ASTM D638, D790, D1876, D882, ISO 527, ISO 178, ISO 1133, EN 13432, and USP . When operated with NEXYGEN Plus 3 under configured audit trail and electronic signature settings, the system meets FDA 21 CFR Part 11 requirements for electronic records and signatures in regulated environments.

Software & Data Management

NEXYGEN Plus 3 serves as the unified software platform for instrument control, method development, real-time visualization, and report generation. Its library includes over 200 preconfigured test methods compliant with ASTM, ISO, EN, and DIN standards — each parameterized with default tolerances, calculation rules, and graphical overlays. Users may create fully customized test sequences using drag-and-drop logic blocks, conditional branching, and embedded mathematical functions. Raw data exports natively to CSV, XML, or proprietary .nxs format; direct integration with Microsoft Excel and Word enables automated population of corporate templates, eliminating manual transcription errors. All data files are timestamped, versioned, and linked to operator ID, instrument serial number, and calibration certificate metadata — supporting GLP and GMP audit readiness.

Applications

• Tensile strength and elongation testing of films, fibers, and molded plastic parts per ASTM D882 and ISO 527
• Compression modulus and crush resistance evaluation of foams, gels, and pharmaceutical tablets per USP
• Peel adhesion quantification of pressure-sensitive tapes and laminates per ASTM D903 and FINAT FTM 1
• Tear propagation resistance of nonwovens and packaging materials per ASTM D1938 and ISO 6383
• Insertion and extraction force profiling of hypodermic needles, catheters, and connectors per ISO 7886-1
• Cyclic loading and relaxation behavior assessment of elastomeric seals and O-rings per ASTM D1053
• Bending stiffness and flexural modulus determination of thin composite panels per ASTM D790

FAQ

Does the LS5 require external calibration services after installation?
No — the system ships with factory-certified calibration certificates for load cell and crosshead position. Users may perform periodic verification using traceable reference weights and displacement gauges per ISO 7500-1 procedures.
Can NEXYGEN Plus 3 generate PDF reports with digital signatures?
Yes — when configured with role-based user accounts and enabled audit trail logging, the software generates tamper-evident PDF reports containing embedded electronic signatures compliant with 21 CFR Part 11.
Is the LS5 compatible with third-party environmental chambers?
Yes — the machine features standard analog I/O ports and Ethernet connectivity to synchronize temperature/humidity chamber parameters with test execution and embed environmental metadata into result files.
What maintenance is required for long-term reliability?
Routine maintenance includes quarterly lubrication of lead screws, annual verification of load cell linearity, and biannual inspection of grip jaw surfaces for wear — all documented in the included service manual.
Can test methods be exported and shared across multiple LS5 instruments?
Yes — NEXYGEN Plus 3 allows export of complete method files (.nxf), including test logic, calculations, and report templates, ensuring method harmonization across distributed labs or production sites.
