Here at NextGen Material Testing, we offer a comprehensive range of universal testing machines designed to match the needs of modern laboratories and production facilities. It is the purpose of this article to introduce our compact bench-top solution – the NG-EML Single Column Universal Testing Machine (50N-5kN). Designed for precision, ease of use, and low-force testing, this electromechanical system is suitable for an array of routine and standardized applications.

We will begin by explaining what a bench-top universal testing machine is and how it differs from larger systems. Then, we will present an overview of the NG-EML model, followed by a breakdown of the specific tests it performs. The article will also cover the main features, technical parameters, accessories, and calibration standards associated with the machine. Lastly, we will discuss who can benefit from this solution and why it is a valuable addition to any quality control or testing environment.

What Are Bench Top Universal Testing Machines?

It is widely recognized that floor-standing universal testing machines (UTMs) are the standard for high-capacity material testing. These large, dual-column systems are engineered to handle substantial loads, often exceeding 100 kN, making them ideal for testing metals, construction materials, and other heavy-duty applications. However, when laboratory space is limited or when testing smaller specimens, bench-top UTMs offer a practical alternative.

Bench-top universal testing machines provide the same fundamental capabilities as their floor-standing counterparts, including tensile, compression, and flexural testing. The primary distinction lies in their compact, single-column design, which allows them to fit comfortably on a laboratory bench. Typically, bench-top UTMs accommodate load capacities ranging from 0.5 kN to 50 kN, making them suitable for testing plastics, composites, textiles, and other materials that do not require high-force applications.
