General Items(38)

Quick answer: STEMAids manufactures and supplies 25 general physics lab items across six groups: precision measuring and weighing instruments from ₹140, electrical wires and resistance elements from ₹20, magnetism apparatus from ₹120, calorimetry and heat-transfer equipment from ₹30, and renewable-energy demonstration models from ₹240 — all listed on stemaids.com on 28 August 2026. Eduscope Smart Learning Solutions Private Limited is Udyam-registered for laboratory equipment manufacturing (UDYAM-DL-06-0069460) and ISO 9001:2015 certified, supplying schools, colleges and vocational institutes across India and for export.

STEMAids supplies general physics demonstration items as part of its Physics Instruments Manufacturer and Physics Lab Equipment Supplier range for schools across Delhi and pan-India.

General Items is where the small, frequently reordered apparatus that every physics lab consumes lives — the calorimeter that measures specific heat, the spool of nichrome wire for a resistance experiment, the horseshoe magnet a teacher has used every year since the syllabus was written. None of these are the centrepiece of a single big-ticket purchase the way an oscilloscope or a spectrometer is; they are the recurring consumables and demonstration models that keep a CBSE or state-board practical schedule running term after term. Reordering the wrong gauge of wire or a magnet too weak to deflect a compass needle wastes a practical period, so specification still matters even at this end of the price list.

What the General Items range covers

The wire group is worth specifying carefully: constantan and nichrome are the two alloys examiners actually ask students to distinguish in resistivity practicals because their resistance changes very little with temperature, while copper and brass wire serve as low-resistance comparison samples. Ordering the wrong alloy doesn’t just cost a reorder — it produces results that contradict the textbook values students are meant to verify.

Applying the 6-S Framework to General Items

Even at consumable price points, the 6-S Framework keeps a reorder list defensible. Syllabus: match wire alloy, magnet type and calorimeter design to the specific board practical — CBSE, ICSE and state boards specify particular apparatus for resistivity and heat-capacity experiments. Specification: ask for wire gauge (SWG) and alloy purity, magnet pull strength, and calorimeter material and capacity rather than accepting a generic listing. Safety: resistance heating coils and electrolysis rods involve live current and should be issued with basic handling guidance for younger students. Sturdiness: stainless-steel vernier callipers and iron weight boxes should hold calibration across a full academic year of student handling. Spares: wire, weight-box pieces and magnet units are the most frequently reordered line items in this category — budget for termly top-ups rather than a single annual order. Supporting documents: manufacturer specification sheets and the statutory document pack are available via the Tenders page for institutional and government procurement.

Frequently Asked Questions

What is included in the General Items category?

Twenty-five physics apparatus and consumable items that don’t sit under a single dedicated subcategory: precision measuring and weighing instruments, electrical wires and resistance coils, magnetism apparatus, calorimetry and heat-transfer equipment, renewable-energy demonstration models, and pendulum-bob sets, all listed on stemaids.com on 28 August 2026.

Which wire should I order for a resistivity-of-a-wire experiment?

Constantan wire (₹110 per 100gm) and nichrome wire (₹150 per 100gm) are the two alloys most CBSE and state-board resistivity practicals specify, because their resistance is largely temperature-independent. Copper DCC wire (₹130) and brass wire (₹155) are typically used as comparison or connecting-wire samples rather than the primary resistivity specimen.

Do you supply calorimeters for specific heat capacity experiments?

Yes. The Copper Calorimetry Instrument is listed at ₹225 on stemaids.com and is specified for standard specific-heat-capacity practicals at the secondary and senior-secondary level.

What renewable-energy demonstration models are available?

Four models covering the CBSE Class X “Sources of Energy” chapter: an Electric Generator Demonstration Model (₹360), a Small Wind Energy Model (₹290), a Water Power Turbine Model (₹1,040), and a Windmill Activity Kit (₹440) — useful for both classroom demonstration and STEM activity sessions.

Is a horseshoe magnet strong enough for electromagnetic induction demonstrations?

The Horseshoe Magnet (₹130) is specified for standard school-level magnetic field and induction demonstrations. For sonometer-linked electromagnetic experiments, the dedicated Electromagnet for Sonometer (₹155) is the better-matched apparatus.

Is STEMAids a registered manufacturer of these items?

Yes. Eduscope Smart Learning Solutions Private Limited is a Udyam-registered micro manufacturing enterprise (UDYAM-DL-06-0069460) and is ISO 9001:2015 certified. See the About page for the full registration and certification details — manufacturer-stated, verify before citing in procurement documents.
