Precision Slotted Mass Set 2.5kg

Quick Answer: The Precision Slotted Mass Set 2.5kg from LabEquip is a physics laboratory mass set used for applying known nominal loads during mechanics, force and motion experiments. It suits secondary-school, college and university laboratories that need removable masses for pulley systems, spring experiments, moments, acceleration studies and other controlled loading activities.

Description

This set provides a nominal combined mass capacity of 2.5 kg made up of individual slotted weights. Slotted masses are designed to be added to or removed from a compatible hanger so students can build up a load in steps and observe how force, extension or motion changes as mass is varied. This makes the set useful across Hooke’s law, simple pendulum, inclined plane, pulley and Newton’s second law style experiments.

The exact number of individual pieces, their unit denominations and the material finish are not specified for this listing — please confirm these details with our sales team before ordering if your experiment plan requires a particular breakdown of masses.

Care & Maintenance / Safety Note

• Store the masses together in a dry place to reduce the risk of surface corrosion.
• Handle with dry hands or forceps where possible, and avoid dropping the masses, since impacts can chip edges and affect measurement accuracy.
• Check that each mass slots securely onto the hanger before applying load, and keep hands clear of a loaded hanger that could swing or fall.
• Inspect masses periodically and set aside any piece that looks rusted, chipped or deformed, since this can throw off experimental results.

Frequently Asked Questions

What experiments is this mass set used for?
It is commonly used for Hooke’s law, pulley and inclined-plane experiments, simple pendulum work, and any activity requiring a stepped, known load.

How many individual weights are included?
The exact piece count and denominations are not specified for this listing. Please contact our sales team to confirm before you order.

Is a hanger included with the set?
Hanger compatibility and whether a hanger is included are not specified for this listing — please confirm with our sales team.

How should I store the masses to prevent rust?
Keep them together in a dry location, avoid handling with wet or sweaty hands where possible, and wipe off any surface moisture promptly.

Can this set be used at both school and university level?
Yes, slotted mass sets of this type are suitable for a range of levels from secondary school through university mechanics coursework.

What should I do if a mass looks damaged?
Set it aside and avoid using it for precision work, since chips or deformation can affect the accuracy of your measured load.
