Jlab Export is a leading Slotted Weight Iron Rust C.P.Proof (Set of five) Manufacturer,and suppliers in India
Slotted Weight Iron Rust C.P.Proof (Set of five) (code EL-MI-2145) is a set of five iron slotted weights of one size, finished against rust, used on weight hangers for loading springs, wires and strings in school and college physics practicals. Sets are listed in 10 g, 20 g, 50 g, 100 g and 500 g sizes; the smaller sizes are chrome plated and the 500 g weights are black powder coated. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Slotted Weights?
| Slotted weights | Material and finish | Sizes listed |
|---|---|---|
| This set (EL-MI-2145) | Iron; chrome plated, 500 g black powder coated | Sets of five: 10, 20, 50, 100 and 500 g |
| Slotted Weight Brass C.P | Brass, turned from rod; chrome plated or brass polish | 5, 10, 20, 50 and 100 g in fives; 50 and 100 g in tens |
| Slotted Weight (Iron Black Painted) | Cast iron, black painted | Sets for large loads, such as sonometer work |
| Metric Slotted Weight Set | Not stated in its listing | 8 weights from 10 g to 500 g, including two each of 20 g and 200 g, with a weight rack |
This iron set gives five identical, rust-protected weights per size, up to 500 g each, for loading in equal steps; the brass weights are turned from rod and carefully adjusted, the black painted cast-iron weights are aimed at large loads, and the metric set covers many values on one rack.
What Are Slotted Weights Used For?
The slot lets each weight slide onto the stem of a hanger, so a load can be built up or reduced one step at a time without unhooking anything. That makes slotted weights basic mechanics lab equipment for the class 11 physics practicals on the spring constant of a helical spring (Hooke’s law), Young’s modulus of a wire with Searle’s apparatus, and the tension in a sonometer wire, as well as moments, pulleys and friction experiments in lower classes. Five equal weights per set give five equal steps of load, which suits experiments where extension or frequency is plotted against load. Stagger the slots as you stack the weights so the load hangs evenly, add and remove them gently, and keep them dry so the plating and powder coat last.
Frequently Asked Questions
What does one set contain?
Five iron slotted weights of the same size — 10 g, 20 g, 50 g, 100 g or 500 g, as you choose.
Why is the 500 g set a different colour?
The 10 g to 100 g weights are chrome plated, while the 500 g weights are black powder coated. Both finishes protect the iron from rust.
Is a hanger included?
No hanger is listed with the set. JLab lists slotted weight hooks and hangers separately; add one to the same enquiry.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a mechanics and physics lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The slotted weights are made at its own works rather than bought from a trader, so schools, colleges, dealers and importers order from the manufacturer itself, and every set is visually inspected before dispatch. JLab exports worldwide and ships to buyers in every region — for example the Dominican Republic in Central America and the Caribbean, Hong Kong in East Asia, Lesotho in Southern Africa, Bahrain in the Middle East and Ethiopia in East Africa.
Hangers and Apparatus That Use Slotted Weights
- Slotted Weight Hook — a steel rod with a hook that carries the weights.
- Searle’s Apparatus — for Young’s modulus of a wire under increasing load.
- Sonometer — for how the pitch of a stretched string depends on tension and length.
- Hooke Law Apparatus — for extension of a spring against load.
More weights are in the Measuring Instruments range.
