What Is the 12V Ray Box Used For?

A ray box turns a bulb into thin, well-defined beams that students can trace on paper, the foundation of ray optics. With a mirror, glass block or prism placed in the beam, pupils measure angles of incidence, reflection and refraction, find the critical angle and see how lenses bring rays to a focus. Only a minimum of accessories is needed to cover a wide range of optics experiments, which makes the ray box a core item of optics lab equipment.

Because two openings can be used at once, one box can serve two groups working on opposite sides, reducing the number of units a class needs. Run it from a separate 12 V supply, let the housing cool before changing the bulb, and dim the room lights slightly for the sharpest rays. The blanking plates close any opening that is not in use so stray light does not disturb the neighbouring group.

What to Specify When Ordering

  • Number of ray boxes, remembering that one box can serve two groups.
  • A 12 V power supply, since none is included.
  • Extra slit plates, a cylindrical lens, prisms or blocks for your planned experiments.
  • Spare 12 V, 24 W B15 bulbs.

Pack sizePack of 2
Length84 mm
Width50 mm
Thickness1 mm
Product codeSLE/PHY/285
Supplied byJain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India

What Are Raybox Slit Plates Used For?

A raybox on its own gives a broad patch of light; a slit plate placed in the raybox opening turns it into thin, clearly defined rays that students can trace on paper. With those rays they study reflection at plane and curved mirrors, refraction through glass blocks and prisms, total internal reflection, and how converging and diverging lenses bend parallel rays to a focus. Clear, narrow rays make angle measurements with a protractor far more accurate.

Because each plate is only 1 mm thick, handle it by the edges, keep it flat and store the pair together so neither gets bent or scratched. Darkening the room slightly and placing the raybox close to the paper gives the sharpest rays. Thin accessories like these are easily mislaid in busy classes, so a spare pack per laboratory keeps ray optics lessons running.

What to Specify When Ordering

  • Number of packs; each pack contains 2 slit plates.
  • The raybox model you use, so we can confirm the 84 x 50 mm plates fit its openings.
  • Whether rayboxes, lenses or glass blocks should be quoted as well.

Reed Relay

Product Code : SLE/PHY/286

Reed Relay (Product Code: SLE/PHY/286) is a single pole changeover switching unit used to charge and discharge a capacitor many times per second in school and college physics laboratories. Driven by a power signal generator, it changes over at 5 to 400 Hz, so students can find capacitance from a steady average current. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for physics lab equipment buyers in India and international markets.

Specifications

ParameterDetail
TypeSingle pole changeover reed relay
Switching rate5 to 400 changeovers per second when driven by a power signal generator
Coil driveCoil operates at up to 400 Hz
Maximum contact rating12 V, 10 mA
Contact protectionContact current-protected by a 12 ohm resistor
Main applicationRepeated charge and discharge of parallel plate capacitors
Product codeSLE/PHY/286
Supplied byJain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India

What Is the Reed Relay Used For?

The reed relay is the switching heart of the classic vibrating-switch method for measuring capacitance. Its changeover contact connects a parallel plate capacitor to a DC supply, then discharges it through a sensitive current meter, once in every cycle of the drive signal. Because the capacitor charges and discharges f times per second, the meter shows a steady average current I = fCV, and students calculate C from their readings.

Changing the frequency on the signal generator, the plate separation or the plate area turns one set-up into a full graph-based investigation, including an estimate of the permittivity of free space. It suits senior secondary and undergraduate electricity practicals. Keep the charging circuit within the 12 V, 10 mA contact rating, start at a low switching rate and raise it gradually while watching for a stable meter reading.

What to Specify When Ordering

  • Number of reed relay units, usually one per working group.
  • Whether you also need a power signal generator to drive the relay coil.
  • Parallel plate capacitor and a sensitive meter for the discharge current.
  • Delivery location, so the quotation can include packing and freight.

Resistance Coil

Product Code : SLE/PHY/287

Resistance Coil (Product Code: SLE/PHY/287) is a 1 ohm resistance unit used to add a known resistance to a circuit in basic electrical experiments in schools and colleges. Instead of a bare resistor, the coil is built into a block with 4mm sockets, so students connect it quickly with standard leads, keeping no more than 0.7 V across it. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for Ohm law experiment kits and general circuit work.

Specifications

ParameterDetail
Resistance1 ohm
Maximum voltage0.7 V
Connections4mm sockets
FormatResistance unit in block form, used in place of a simple resistor
ApplicationAdding resistance to any circuit in basic electrical experiments
Product codeSLE/PHY/287
Supplied byJain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India

What Is the Resistance Coil Used For?

A 1 ohm coil is a convenient known resistance for introductory circuit work. Students place it in series with a cell and an ammeter to see how current changes, use it with a voltmeter to confirm Ohm’s law, or connect several units in series and parallel to compare combined resistance with the calculated value. Because the block takes 4mm plugs, a circuit can be built, changed and checked in minutes without soldering or loose wire ends.

A low value like 1 ohm is also useful as a current-sensing resistance: the voltage across it in volts equals the current through it in amperes. Keep the voltage across the coil to 0.7 V or less, which by Ohm’s law limits the current to about 0.7 A, and switch off between readings so the coil does not warm up and drift.

What to Specify When Ordering

  • Number of 1 ohm Resistance Coil units per bench or per class set.
  • Whether you also need 4mm connecting leads, meters or a low-voltage supply.
  • Any other resistance values your practicals call for, so we can check what else is available.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies the Resistance Coil from Ambala, Haryana, to schools, colleges, institutes and dealers. The coil can be quoted as part of a complete electricity bench, together with meters, leads and resistance boxes, which saves buyers from sourcing each part separately. Company background is on our profile page.

Related Physics Lab Equipment

  • Resistance Box — selectable resistance values when one fixed coil is not enough.
  • Decade Resistance Box — wider range of values in single steps for comparison work.
  • Rheostat — varies the current smoothly in the same circuit.
  • Ammeter Voltmeter — measures current and voltage for Ohm’s law readings.
  • Stackable Leads — connect the 4mm sockets to the rest of the circuit.

See all items in our Physics Lab Equipment category.

Frequently Asked Questions

What is the resistance value of the Resistance Coil?
The Resistance Coil has a value of 1 ohm. It is built into a block with 4mm sockets so it can be added to any basic electrical circuit, and several units can be combined in series or parallel.

What is the maximum voltage for the Resistance Coil?

Resonance Apparatus with Brass Tube

Product Code : SLE/PHY/288

Resonance Apparatus with Brass Tube (Product Code: SLE/PHY/288) is an air-column apparatus used to study sound resonance and estimate the speed of sound in school and college physics laboratories. Two metal tubes telescope into each other on a removable base, so students can set the air column anywhere from 300 mm to 530 mm. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

ParameterDetail
TubesTwo metal tubes telescoping into each other (brass tube)
Air column lengthAdjustable from 300 mm up to 530 mm by moving the outer tube
MountingFitted on a removable base
ApplicationResonance investigations in air columns
Product codeSLE/PHY/288
ManufacturerJain Scientific Equipments Pvt Ltd (ScienceLab) — OEM
Country of originIndia (made in Ambala, Haryana)

What Is the Resonance Tube Apparatus Used For?

Students hold a sounding tuning fork, or a small loudspeaker driven by a signal generator, just above the open end and slide the outer tube until the note swells to a clear maximum. That length marks a resonance of the air column. In a column closed at the lower end, the first resonance is close to a quarter of a wavelength plus a small end correction, so a known frequency leads to the wavelength and then to the speed of sound from v = fλ.

Repeating the measurement with several forks and plotting length against the reciprocal of frequency turns this resonance tube experiment kit into a graph-based practical that also yields the end correction. Because the length is changed by sliding metal tubes rather than by raising a water level, set-up is dry and quick. Approach each resonance from both directions, average the two positions and note the room temperature, since the speed of sound depends on it.

What to Specify When Ordering

  • Number of Resonance Apparatus with Brass Tube sets, usually one per student group.
  • Your sound source: tuning fork sets, or a signal generator with a loudspeaker.
  • Whether the order is for your own laboratories or for resale as a dealer or importer.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the original equipment manufacturer (OEM) of this resonance apparatus. The telescoping tubes and base are made and assembled at the company’s own licensed factory at Saha, Ambala, Haryana, India, instead of being bought in from a trader, and each order is supplied factory-direct to schools, colleges, institutions, dealers and importers.

For purchase files, the company is incorporated as Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597) and produces this apparatus at 449, HSIIDC Industrial Area, Saha, Ambala, under Factory Licence AMB-ONLINE-CHD-J-414.

Sealed Radioactive Source, Cobalt

Product Code : SLE/PHY/289

Sealed Radioactive Source, Cobalt (Product Code: SLE/PHY/289) is a 5 µCi (185 kBq) cobalt-60 teaching source used to demonstrate gamma radiation in school and college physics laboratories. An aluminium disc over the active material absorbs the beta particles, so only gamma rays leave the source, and the mount is colour-coded green. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for nuclear physics lab equipment set-ups in India and international markets.

PackingSmall lead castle in a labelled MDF storage box, 100 x 75 x 65 mm high
DocumentationData sheet enclosed
Product codeSLE/PHY/289
Supplied byJain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India

What Is the Cobalt-60 Source Used For?

Because the beta component is filtered out, the cobalt source gives a clean gamma beam for the parts of a radioactivity course that alpha and beta sources cannot cover. With a Geiger-Muller tube and counter, students show that gamma rays pass through paper and aluminium almost unchanged and are reduced only gradually by thickening layers of lead. Moving the detector away in measured steps lets them test the inverse-square law, and a magnet placed in the beam shows that gamma rays, unlike beta particles, are not deflected.

Good practice follows the time, distance and shielding rule. Lift the source by its 4 mm stem with tongs, point the window away from people, take readings promptly, and return the source to its lead castle and labelled box straight after use. Keep a written log of each use, store the box in a locked cupboard, and remember that with a 5.26-year half-life the count rate drops noticeably over several years of teaching.

What to Specify When Ordering

  • Quantity of cobalt-60 sources, and whether strontium or americium sources are needed as well.
  • Any registration or authorisation reference your institution holds for sealed radioactive sources.
  • Whether a GM tube holder, counter or scaler should be quoted with the source.
  • Full delivery address and country, as transport rules for radioactive material vary.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited in Ambala, Haryana, India. The company sources this cobalt-60 teaching source for schools, colleges and institutes, and can quote it together with the detectors and counters used in the same practical. Because radioactive sources are controlled materials in most countries, we confirm documentation and delivery requirements with each buyer before supply. See our company profile for more about us.

What Is the Strontium-90 Source Used For?

The strontium source is the standard way to show how beta particles behave. Placed in front of a GM tube, it gives a count that paper barely changes but that falls steeply as aluminium sheets of increasing thickness are added, so students can plot absorption curves and estimate the range of the particles. Holding a strong magnet beside the beam bends the particles and moves the count, which demonstrates that beta radiation is charged.

The yttrium-90 daughter has a half-life of only 64 hours, so it stays in equilibrium with the strontium and the source decays at the 28-year rate of strontium-90. In practice the count rate changes very little over a school career, which suits long-term comparison of results. Use tongs, keep the open window facing away from the body, subtract the background count before every reading, and return the source to its lead castle as soon as the measurement is complete.

Frequently Asked Questions

What type of radiation comes from the Sealed Radioactive Source, Strontium?
The Sealed Radioactive Source, Strontium emits beta particles. Its strontium-90 and yttrium-90 are incorporated in a silver disc that allows the major proportion of the beta radiation to escape, which makes it the usual choice for beta absorption and deflection practicals.

How long does the Sealed Radioactive Source, Strontium last?
The Sealed Radioactive Source, Strontium decays with the 28-year half-life of strontium-90, while its yttrium-90 daughter has a 64-hour half-life and stays in equilibrium. The count rate therefore falls only slowly over years of classroom use.

What is the activity of the Sealed Radioactive Source, Strontium?
The Sealed Radioactive Source, Strontium contains 5 µCi (185 kBq) of strontium-90 in equilibrium with yttrium-90. The nature and strength are engraved on the mount, which is colour-coded yellow, and a data sheet comes with each source.

How is the Sealed Radioactive Source, Strontium stored?
The Sealed Radioactive Source, Strontium is supplied in a small lead castle inside a labelled MDF box, 100 x 75 x 65 mm high. Keep the box in a locked, marked store away from students, and log each time the source is taken out.
