The Instron 3345 Universal Testing Machine is a single-column electromechanical materials testing system designed for laboratory testing of materials and components under tensile, compression, flexural, peel, puncture, and other mechanical loading conditions. The instrument visible in the photograph is identifiable as an Instron 3345, part of Instron's 3340 Series single-column testing systems. The 3345 provides a maximum force capacity of 5 kN (1,125 lbf) and is designed for applications where a compact tabletop testing frame and open test area are beneficial.

The Instron 3345 uses closed-loop position control and supports a broad testing-speed range. Published specifications list a maximum speed of approximately 1000 mm/min, a minimum speed of 0.05 mm/min, approximately 885 mm crosshead travel, and approximately 1123 mm vertical test space for the standard 3345 configuration.

The photographed system includes the single-column test frame, crosshead/load area, base, emergency-stop control, and an Air Val accessory visible near the front of the machine. The exact load cell, grips/fixtures, extensometer, controller configuration, software, and other accessories cannot be confirmed from the photograph and should be verified separately.

The equipment shows substantial cosmetic wear, dust, scratches, and marks consistent with previous laboratory or industrial use. Operational condition, force calibration, crosshead movement, load-cell accuracy, emergency-stop function, and software/controller operation should be verified before use.

Applications

The Instron 3345 is suitable for mechanical testing of materials and finished components where forces below 5 kN are required. Typical applications include tensile testing of plastics, films, fibers, rubber, textiles, packaging materials, wires, small components, and other specimens. The machine can also be configured for compression, flexural, peel, puncture, and related mechanical tests using suitable grips and fixtures.

The single-column design provides open access to the test area and is particularly useful for quality-control laboratories, research and development facilities, educational laboratories, production testing, and materials characterization. Instron describes the 3340 Series as suitable for routine standardized quality-control and general-purpose mechanical testing.

Benefits of Refurbished Laboratory Equipment

Purchasing a refurbished Instron 3345 Universal Testing Machine can provide laboratories with access to a professional materials-testing platform at a lower acquisition cost than purchasing a new testing system. Its 5 kN force capacity and broad speed range make it suitable for many routine laboratory and quality-control mechanical testing applications.

Refurbished Instron equipment can be particularly useful for universities, research laboratories, plastics and polymer testing facilities, packaging laboratories, manufacturing quality-control departments, and engineering laboratories. Existing compatible grips, load cells, extensometers, fixtures, and software can potentially be reused depending on their compatibility and condition.

Additional Information

The photographed equipment is an Instron 3345 Universal Testing Machine. The image shows the primary testing frame and associated equipment, but it does not clearly confirm the installed load-cell capacity, grips, extensometer, computer/controller, software license, or complete accessory package. Buyers should verify these items before purchase.

The machine has visible cosmetic wear, scratches, dust, discoloration, and marks from previous use. The orange Air Val accessory visible beside the frame is shown in the photograph but its exact function and inclusion with the machine should be confirmed separately. Calibration status, load-cell condition, crosshead movement, emergency-stop operation, electrical condition, and software/controller functionality should be tested before the instrument is placed into production use.
