Applications and Experiments for the Semi-Analytical Scale
The scale weighs reagents, seeds, leaves and small specimens up to 200 g in practical classes, while its counting, percentage and density modes support growth, composition and material-property exercises. The weighing stones, the small reference weights of the set, let students see how known masses read on the scale.
- Class 9–12 chemistry: weighing solids for solutions, using a 70 mm glass Hour Glass (watch glass) as a weighing dish.
- Class 11–12 biology: recording fresh and dry mass of seeds or leaves in growth and water-content experiments.
- Density determination of small solids, with volume found by displacement in one of the Glass Cylinders with Different Pupils.
- Percent weighing for composition exercises and piece-counting of small identical items.
Place the scale on a firm, level bench away from draughts, tare the weighing dish before adding a sample, and handle the weighing stones with forceps rather than fingers.
Standard Scope of Supply
Each set includes the semi-analytical scale in its die-cast aluminium housing and eight weighing stones: one 10 mg, two 20 mg, one 50 mg, one 100 mg, two 200 mg and one 500 mg piece. The power arrangement and any carrying case are confirmed on the quotation.
Packing, MOQ and Lead Time
One scale for a preparation room or several for student benches can be quoted. Each quotation covers packing for a weighing instrument, delivery time and price for the quantity named, and watch glasses or weighing bottles can join it on the same document.
Registered with an Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Kenya, Ghana, Ethiopia, Tanzania, Uganda and the UAE.

Frequently Asked Questions
What are the weighing stones?
They are the small reference weights that accompany the scale: eight pieces of 10 mg, 20 mg (two), 50 mg, 100 mg, 200 mg (two) and 500 mg. Placed on the pan, they show students how known masses register on the scale.
How much can the scale weigh, and how finely?
It weighs up to 200 g with a sensitivity of 100 mg. That suits most school and college sample weighings; for milligram-level analytical work, a higher-resolution balance should be specified in the enquiry.
What functions does it have besides weighing?
The scale offers a variety of measurement units plus piece-counting, percent weighing and density determination, so one instrument covers mass, counting, composition and density exercises.
Who supplies these scales?
Science Lab Supplies supplies them from Ambala, India, and can quote them alongside other balances, weighing bottles and glassware for a biology or chemistry laboratory fit-out.
