Product Code : SCL-AM-12096
Laboratory Slotted Masses, 2.5 kg (SKU SCL-AM-12096) is a set of a 500 g hanger and four 500 g slotted steel discs that lets students apply a known load in 500 g steps up to 2.5 kg. It is used for spring, force and balance practicals in school and college physics labs. Science Lab Supplies manufactures the set at its factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and supplies it direct to schools, colleges and distributors.
Specifications
All technical details of the set are listed in the table below. In short, it is a carbon steel hanger and four slotted discs with a baked enamel finish, each held within ±0.5% of its marked mass and designed to stack securely on the hanger rod.

Applications and Experiments for the Slotted Mass Set
The set gives known downward loads for mechanics practicals: students hang it from a clamp, add the 500 g discs one at a time and record the effect of each step, making it useful mechanics lab equipment in India for school and college benches.
- Class 11–12 physics: loading a spring in 500 g steps to plot extension against force, for example on the Hooke's Law Apparatus.
- Checking the readings of spring balances and analogue string balances against known masses.
- Turning-effect and equilibrium work with the Moments Disc Apparatus and the Parallelogram Force Apparatus.
Lower each disc gently onto the one below, and never stand directly under a loaded hanger.
Standard Scope of Supply
Each set contains one 500 g steel hanger rod with a base plate and reinforced top hook, four 500 g slotted steel discs and a polymer storage container. A laboratory stand, clamp and springs are not included and can be quoted separately.

Frequently Asked Questions
How is the 2.5 kg made up?
It consists of one 500 g hanger rod and four 500 g slotted discs, so the load rises from 500 g to 2.5 kg in five equal steps of 500 g each.
Will the discs fit hangers we already have?
Each disc has a 5.5 mm wide slot, which slides over hanger shafts of 5 mm diameter. Check the shaft size of your existing hangers before mixing them with this set.
How should the masses be looked after?
Wipe the discs with a clean, dry cloth, keep them in the supplied container between lessons, and avoid dropping them on hard benches so the stacking steps and enamel finish stay undamaged.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer. The slotted mass set is made at its own factory in Saha, Ambala, India, and quotations for it come straight from the factory without a trading house in between.
