Metals Set of 20 STEM Lab Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12484
The Metals Set of 20 STEM Lab manufactured by Educational Instrument India is a premium material science and metallurgy collection engineered explicitly for advanced physics, chemistry, and vocational engineering labs. Designed to satisfy modern STEM frameworks, this comprehensive collection consists of 20 distinct, precision-machined metal and alloy specimens. It provides students with a tactile platform to analyze and cross-compare structural, electronic, thermal, magnetic, and chemical characteristics.
To allow strict control of variables during standardized laboratory experiments, each specimen is cut to identical dimensions. Whether students are calculating densities via mass-to-volume displacement, analyzing electron behavior through electrical resistance testing, or determining the galvanic activity series through acid interactions, this kit delivers consistent, highly repeatable empirical results. It is an indispensable cornerstone for primary and secondary schools, space science workshop clusters, university engineering branches, and testing facilities across India and worldwide export networks.
Unlike basic generic starter packs, this curated 20-piece array blends fundamental elemental blocks with core industrial-grade alloys:
Aluminum (Pure)
Brass (Cu-Zn Alloy)
Bronze (Cu-Sn Alloy)
Copper (Electrolytic)
Iron (Soft Wrought)
Lead (Safety Sealed)
Nickel (Pure)
Zinc (Galvanic Grade)
Magnesium (High Purity)
Stainless Steel (Grade 304)
Tin (Pure Element)
Titanium (Grade 5/Medical)
Tungsten (High Density)
Bismuth (Crystalline Form)
Cobalt (Alloy Base)
Carbon Steel (Medium Carbon)
Chromium (Plated Specimen)
Monel Metal (Ni-Cu Alloy)
Inconel (Superalloy Base)
Nickel Silver (Cu-Ni-Zn)

- How to Use It (Step-by-Step Laboratory Guide)
This multi-disciplinary material science pack supports various chemistry and physics laboratory protocols. Below are standard guidelines for running classroom experiments:
Experiment A: Density Verification via Volume Displacement
Have students weigh a designated sample (e.g., Titanium) using a precise electronic balance.
Fill a graduated cylinder with a known volume of water, submerge the sample entirely, and record the volume shift.
Calculate empirical density using the standard equation:
Compare the calculated value against the Educational Instrument India master reference manual to identify unknown metals.
Experiment B: Electrical Conductivity Profiles
Secure a specimen into a low-voltage circuit connected to a digital multimeter.
Measure the voltage drop across the uniform length of the sample block to compute its electrical resistivity.
Contrast electron configuration efficiency directly between pure Copper and complex Stainless Steel.
Experiment C: Magnetic Susceptibility Classification
Bring a powerful neodymium magnet close to each of the 20 samples.
Classify each specimen as Ferromagnetic (e.g., Iron, Cobalt, Nickel), Paramagnetic, or Diamagnetic (e.g., Bismuth, Copper) based on its magnetic attraction.
Experiment D: Chemical Activity Series Mapping
Place small, localized drops of dilute hydrochloric acid (HCl) onto the surfaces of different metals in a well-ventilated space.
Observe the hydrogen gas bubble evolution rates to construct an empirical activity series spanning from Magnesium (highly reactive) to Copper (inert).
- Frequently Asked Questions (FAQs)
Q1: How are the individual metals identified within the set?
A: Every specimen from Educational Instrument India features an alphanumeric code engraved directly into its surface. This code maps to an included master documentation matrix, making it easy for teachers to manage blind identification tests.
Q2: Are hazardous specimens like Lead safe for student use?
A: Yes, our Lead sample features a micro-thin, clear, non-reactive polymer sealant layer. This effectively eliminates direct dermal heavy-metal exposure while preserving its characteristic mass, weight, and high-density profile.
Q3: Can these samples withstand high heat testing for specific heat capacity labs?
A: Absolutely. These solid specimens are designed for rigorous thermochemical exploration and can be repeatedly boiled or heated within typical laboratory calorimeter limits without causing structural breakdown or warping.
Q4: How does this set align with Google's E-A-T and educational standards?
A: Every set is assembled using highly pure elemental stock and certified industrial alloys. The accompanying documentation is reviewed by professional metallurgists, ensuring that your classroom data matches official international scientific baselines.
