Energy Absorbed At Fracture
Product Code : LSK-MTE-10507
Energy Absorbed At Fracture (SKU LSK-MTE-10507) is a small-scale, bench-mounting notched-bar impact tester that swings a pendulum through a specimen and reads the energy absorbed in joules. It introduces impact testing and resistance to crack propagation in materials labs at engineering colleges, polytechnics and training institutes. Science Lab Supplies manufactures it at Saha, Ambala, India (Plot 448, HSIIDC Industrial Area) and offers it to colleges, tender contractors and distributors without a middleman.
Specifications
The apparatus has three parts: a main unit, an instrumentation unit and a power supply. In the main unit a pendulum hangs in a rigid frame on low-friction bearings, with an angular encoder at the pivot. An interlocked guard encloses all moving parts, and adjustable feet level the base.

Applications and Experiments for the Energy Absorbed At Fracture Tester
Students compare how much energy different metals absorb when a notched specimen is broken by a single impact. The results show toughness and resistance to crack propagation, contrasting ductile and less ductile behaviour among plain carbon steel, brass, copper and aluminium.
- B.E./B.Tech mechanical and metallurgy: notched-bar impact test and material toughness.
- Materials science practicals: comparing energy absorbed by ferrous and non-ferrous metals.
- Diploma engineering and TVET: safe introduction to common impact testing techniques.
Students raise the pendulum to its start position, where an electromagnet holds it, clamp a specimen in the holder and slot it into the base. The instrumentation unit releases the pendulum and displays the result.
Standard Scope of Supply
The set comprises the main pendulum unit with guard, the instrumentation unit, the power supply, a specimen holder, lengths of plain carbon steel, brass, copper and aluminium, plus a hacksaw and a cutting jig. The jig keeps the notch position repeatable, so specimens made in the lab give comparable results.
Packing, MOQ and Lead Time
Pricing is available for one tester or a set for a larger materials lab. Each quotation lists packing, delivery time and price for that number of units, and extra material lengths or other test and measurement instruments in India from this range can be quoted alongside.
Science Lab Supplies, registered as an exporter with an Importer-Exporter Code, can ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia.

Frequently Asked Questions
How are test specimens made?
Lengths of each specimen material are included with a hacksaw and cutting jig, so the lab cuts its own notched specimens. The jig repeats the notch position, giving valid comparisons between tests.
Is the pendulum safe for student use?
The apparatus is fully enclosed by an interlocked guard over all moving parts, and release is controlled from the instrumentation unit. Tests should still be run under staff supervision.
Is Science Lab Supplies the actual manufacturer?
Yes. The impact tester is built at the company's Saha, Ambala facility, so buyers deal with the maker for specifications, quotations and supply.
What does the display show?
The instrumentation unit shows the pendulum's angular position before and after impact and directly displays the energy absorbed by the impact in joules.
