How Does It Compare with Other JLab Weight Sets?
| Set | Weights | Range | Case and other listed details |
|---|---|---|---|
| This A grade box (EL-MI-2138) | Class A brass | 1 mg–100 g or 1 mg–200 g | Teak wood box, sun-mica top; test certificate; wire fractional weights |
| Analytical Weight Boxes Brass Wt(B Grade) | B grade brass, nickel plated | Capacity 100 g, with a box of fractional weights | Tough plastic box |
| Physical Weight Boxes (Brass C.P) | Brass | 100 g or 200 g | Polished teak box with sun-mica top; forceps and fraction weights included |
| Analytical Weight Box -1g to 500g | Analytical weights, 12 pieces | 1 g to 500 g | Heavy wooden storage box |

Choose the A grade box when the weights must come with a test certificate, for example in analytical teaching labs and tenders that ask for documented weights. The B grade box is a lighter, plastic-cased 100 g set for routine school use, and the 1 g to 500 g box suits heavier loads on bigger balances.
What Is an Analytical Weight Box Used For?
A box of analytical weights supplies the known masses that a two-pan beam balance compares against. In chemistry lab equipment it is used with an analytical or chemical balance to weigh primary standards for titrations, samples for gravimetric analysis and small quantities of reagents; in physics it serves density, specific heat and other experiments that need a mass to be known accurately. Because the set runs from 1 mg upward, any mass up to the set capacity can be built from a combination of pieces, and the 1 mg to 500 mg wire weights take care of the final fraction. Laboratories also use a set like this to check that their balances still read correctly.
Always lift the weights with forceps rather than fingers, because skin oil and moisture change the mass of small pieces. Return each weight to its own recess, keep the lid closed when the box is not in use, and clean the weights only with a soft brush so the surfaces are not scratched.
What to Specify When Ordering
- Capacity — the 1 mg to 100 g set or the 1 mg to 200 g set.
- Quantity — the minimum order is 10 weight boxes.
- Balances — add the analytical or chemical balance the weights will be used with, if needed.
Frequently Asked Questions
What capacities are available?
Two: a set from 1 mg to 100 g and a set from 1 mg to 200 g. Name the capacity you need in your enquiry.
Is a test certificate supplied?
Yes. Each box comes with JLab’s own test certificate, issued after all the weights in the set have been tested on JLab’s precision electronic balance.
What are the weights made of?
The weights are brass, Class A grade. The smallest pieces, from 1 mg to 500 mg, are wire weights, which are easier to pick up with forceps.
How does the A grade box differ from the B grade box?
The A grade set has Class A brass weights in a teak wood box with a test certificate and comes in 100 g or 200 g capacity. The B grade set has nickel-plated brass masses with a box of fractional weights in a tough plastic box, capacity 100 g.
Who manufactures these weight boxes?
Jain Laboratory Instruments Pvt Ltd (JLab) manufactures them at its works in Ambala, Haryana, India, and supplies them directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of school and college laboratory instruments in India, incorporated in 2017 and located on Hargolal Road, Ambala, Haryana. The A grade weight boxes are made and tested at JLab’s own works rather than bought from a trader, so laboratories, dealers and importers order factory-direct, every box is visually inspected before dispatch, and repeat sets are made by the same manufacturer. JLab exports worldwide and ships to buyers in every region — for example Switzerland in Western Europe, Australia in Oceania, Portugal in Southern Europe, Algeria in North Africa and Belize in Central America and the Caribbean. For tenders, see the JLab lab tenders page.
Balances and Weights to Use With It
- Analytical Balance — a 200 g, 0.1 mg short-beam balance with a rider scale.
- Chemical Balance — a 200 g beam balance supplied without weights.
- Fractional Weight Set Analytical — a separate set of 1 mg to 500 mg weights.
- Analytical Weight Boxes Brass Wt(B Grade) — the plastic-cased B grade alternative.
