Laser (for high school) (Product Code: SCL248/040) is a portable green laser that gives a narrow, bright beam for ray optics and wave optics lessons. Its listed wavelength is 550 nm with a power of 5 mW, and it runs either from a stationary supply or from a rechargeable battery, with the charger included. Physics teachers use it to make reflection, refraction and diffraction visible to a whole class. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as part of its laser experiment range for schools.

Specifications

Typical Use

Aimed at a plane mirror, the beam shows the law of reflection with a precision that ray boxes cannot match; sent through a glass block or prism, it traces refraction and total internal reflection, and a little chalk dust or water mist makes the path visible in the air. Passing the beam through a narrow slit or a fine grating produces a diffraction pattern on a far wall, giving students a way to estimate spacing or wavelength from simple measurements.

Safe handling matters as much as the physics. Never look into the beam or point it at anyone, keep the beam below eye level, remove shiny objects from the bench, and let the teacher keep and switch the laser. Charge the battery fully before practical sessions so the output stays steady. Used this way, it becomes a core part of any optics experiment kit for school laboratories.

Supplier

This laser is supplied by Jain Scientific Equipments Private Limited, the Ambala, Haryana business behind the ScienceLab name, which offers optical accessories so that the full ray optics practical can be ordered together. Read about the company on its profile page.

Dosimeter Digital (Product Code: SCL249/041) is a digital radiation dosimeter used to measure accumulated dose during radioactivity and radiation-safety lessons in school and college physics labs. It reads from 0.1 µSv to 1 000 µSv, weighs no more than 200 g and comes with batteries, so it is ready to use on arrival. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, alongside other nuclear physics lab equipment for teaching.

Specifications

What Is the Digital Dosimeter Used For?

A useful first activity is to leave the dosimeter on a bench for a lesson and read the dose from natural background radiation, which gives the class a baseline for everything that follows. The teacher can then place it near a sealed school source for a fixed time and compare the reading, before repeating the exposure at a greater distance or behind a sheet of shielding to show how dose falls off. Turning these readings into everyday comparisons helps students see why time, distance and shielding are the three rules of radiation safety.

Teachers who handle sources can also carry the dosimeter during practical sessions as a check on their own accumulated dose. Keep it away from strong heat and moisture, switch it off or remove the batteries for long storage, and log readings so the data can be reused in later lessons. It pairs well with a Geiger counter in any radiation experiment kit for India's senior secondary classes.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab from Ambala, Haryana, supplies this dosimeter to schools, colleges and distributors together with its radioactivity apparatus. For vendor and import-export records, the supplying company's Importer-Exporter Code is AAECJ8618A (DGFT) and its GSTIN is 06AAECJ8618A1ZT. See the company profile for more information.

Related Lab Equipment

These items complete a school radioactivity practical:

• Geiger Counter — counts individual events, complementing the dosimeter's dose reading.
• Sealed Radioactive Source, Cobalt — a sealed source for distance and shielding measurements.
• Apparatus for studying the value of the half-decay period during radioactive decay — extends the topic to half-life.
• Digital Chronometer (Stopwatch) — times each exposure so readings can be compared fairly.

More apparatus is available in our Lab Equipment category.

Frequently Asked Questions

What dose range does it measure?
The Dosimeter Digital measures dose from 0.1 µSv to 1 000 µSv and shows the result on a digital display, giving students a direct number for background radiation and for classroom exposure experiments.

Are batteries included?
Yes. Batteries are included with the Dosimeter Digital, so it can be used as soon as it arrives. For long storage between terms, remove the batteries or switch the unit off to avoid unnecessary drain.

Is a calibration certificate available?
A calibration certificate is not stated on the Dosimeter Digital listing. If your institution needs calibration documentation, please contact us before ordering so we can tell you what can be provided with the unit.

Can it be used for official occupational dose records?
The Dosimeter Digital is listed for teaching use. If you need a dosimeter for regulated personal monitoring of radiation workers, discuss your requirements with us before ordering rather than relying on this classroom instrument.

Does it replace a Geiger counter?
Not entirely. The Dosimeter Digital totals the dose received, while a Geiger counter counts individual events and suits count-rate experiments, so many physics departments use both instruments in the same radioactivity practical.

Who supplies the Dosimeter Digital?
The Dosimeter Digital is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. Send the product code SCL249/041, quantity and delivery location through the contact page for a quotation within India or to international markets.

Spectroscope (for high school) (Product Code: SCL255/042) is a prism spectroscope that splits light into its component colours so students can study continuous and line spectra. Light enters through a slit in the collimator tube, is dispersed by a three-edged prism on a table, and is viewed through a telescope with a moving eyepiece, while a micrometer screw allows fine adjustment. As a prism spectrometer for India’s school and junior college optics labs, it is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

Point the collimator at an ordinary filament lamp first: the class sees an unbroken band from red to violet, the continuous spectrum of a hot solid. Swap the lamp for a sodium lamp or a glowing gas discharge tube and the band is replaced by a few sharp bright lines, each one a fingerprint of the element. Comparing these patterns is how students meet the idea that atoms emit only particular wavelengths.

To set up, focus the telescope on a distant object, narrow the slit until lines look sharp, then turn the prism table until the spectrum appears and settle it at the position of least deviation. The micrometer screw helps line up the eyepiece on individual lines when recording their positions. Keep the prism faces free of fingerprints and cover the instrument when not in use; it is a lasting part of the optics lab equipment in any school.

Manufacturer

ScienceLab spectroscopes come from Jain Scientific Equipments Private Limited, a manufacturer of teaching apparatus in Ambala, Haryana, which supplies optics instruments to schools and colleges in India and international markets. Our company profile gives further background.

Spectral Tube Set with Voltage Source (for high school) (Product Code: SCL267/043) contains five gas discharge tubes and the high voltage source needed to light them, so a class can see the characteristic glow and emission lines of different gases. When the source is connected, an electrical discharge passes through the gas and the tube lights up in a colour that belongs to that gas alone. The set is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, and is a natural companion to a spectrometer in India’s school and college physics labs.

Specifications

Typical Use

Fit one tube into the support, switch on, and darken the room: the narrow middle section glows brightly, and each gas gives a visibly different colour, with neon’s red-orange standing out at once. Viewing the glowing capillary through a spectroscope or a direct-vision spectroscope then reveals a set of separate bright lines rather than a rainbow. Hydrogen is usually studied first because its few visible lines are easy to pick out and connect to the energy levels of the atom.

Working through all five gases lets students build their own table of spectral fingerprints and discuss how astronomers identify elements in stars. The source works at high voltage, so switch it off before changing tubes, let each tube cool for a moment, and hold tubes by their ends. Treat the set as teacher-operated physics lab equipment for India’s senior secondary classes.

Manufacturer

Jain Scientific Equipments Private Limited manufactures laboratory apparatus at its factory in Ambala, Haryana, and markets this spectral tube set under the ScienceLab brand for physics and chemistry teaching. More about the company is on our company profile.

Related Lab Equipment

These items are used with the spectral tubes in emission spectra practicals:

• Spectroscope (for high school) — resolves the glow of each tube into separate lines.
• Spectroscope, Direct Vision — lets several students view the lines quickly by hand.
• Hydrogen Spectrum Set — a focused option for detailed hydrogen line work.
• Spectrum Tube Power Supply — an additional source when running two tubes side by side.

Is the voltage source included?
Yes. The set includes a high voltage source with an adaptable support for connecting the tubes. Its power consumption is 4.5 W.

Why is each tube narrow in the middle?
The narrow section concentrates the discharge into a bright, thin line of light, which is ideal for viewing through a spectroscope slit.

Is a spectroscope needed?
The colour differences are visible by eye, but separate emission lines can only be seen with a spectroscope. See the related items above or contact us for a combined quotation.

Can students operate the set?
Because the source produces high voltage, a teacher should connect and switch it. Students can view the tubes and record observations safely from the bench.

Can replacement tubes be ordered?

Generator Model (for high school) (Product Code: SCL280/045) is an open teaching model that shows how mechanical rotation is turned into electrical energy. Every constructive element is visible: the support, the stator coils or permanent magnets, the coil rotor and the copper or carbon blade brushes that carry current out of the moving coil. The model is designed to demonstrate the working principle of a generator in both its alternating current (AC) and direct current (DC) forms. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a demonstration model for the physics lab.

Key Details

Typical Use

The teacher turns the rotor slowly with the output connected to a centre-zero galvanometer. As the coil cuts the magnetic field the needle swings, and students can link each swing to the coil’s position in the field. In an AC generator the current reverses every half turn, so the needle swings first one way and then the other; in a DC generator the current is kept flowing in one direction, and the needle stays on one side of zero. Seeing both behaviours on one open model makes the role of the brushes and the output connection easy to explain.

Turning faster produces larger deflections, which leads naturally to the factors that affect induced voltage: speed of rotation, strength of the field and number of turns. Because nothing is hidden inside a casing, students can trace the path of current from the coil through the brushes to the meter. The model fits any electromagnetic kit for school lessons on power generation and complements motor demonstrations, since a motor is a generator run in reverse.

Manufacturer

This generator model is made by Jain Scientific Equipments Private Limited, an Ambala, Haryana manufacturer that brands its educational apparatus as ScienceLab. For vendor registration, the company’s GSTIN is 06AAECJ8618A1ZT and its LEI is 3358004HRD1JIVXKYX49. Read more on the company profile.

Related Lab Equipment

These items are used with the generator model in electromagnetism lessons:

• Galvanometer, Centre Zero Universal Meter — shows the direction of the output current as the rotor turns.
• Demonstration Motor AC/DC — shows the reverse process of turning current into motion.
• A.C. Generator — a dedicated AC generator for further study.
• Working Model of Dynamo — a working dynamo for comparing with the open model.
• Device to Verify The Lenz’s Law (for high school) — explains why turning the rotor under load takes effort.

Explore the Lab Equipment category for more.

Frequently Asked Questions

Does the model show both AC and DC generation?
Yes. It is designed to demonstrate the working principle of the generator, the AC generator and the DC generator.

Does it use magnets or field coils?
The field is listed as stator coils or permanent magnets, and the brushes as copper or carbon blades. Tell us if your syllabus needs a particular arrangement and we will confirm it.

Is a meter included to show the output?
No meter is listed with the model. A centre-zero galvanometer is recommended; contact us to include one.

Can it light a lamp?
Output depends on how fast the rotor is turned and the arrangement supplied. Ask us before ordering if lighting a lamp is part of your lesson plan.

How should it be maintained?
Keep the brushes and contact surfaces clean and dry, turn the rotor by hand without force, and store the model covered so dust does not settle on the open parts.

What should a quotation request include?
Quote the code SCL280/045, the number of models, delivery location and any tender wording. We supply institutions in India and international markets.

The Model of The Celestial Sphere (for high school) (Product Code: SCL282/046) is a 300 mm transparent celestial globe on a gyroscopic support, with a small Earth shown at its centre. The main reference circles, the celestial equator and the celestial meridians, are marked on the sphere, together with an equatorial or horizontal plane, so students can see how astronomers locate stars on the sky as seen from Earth. This item of astronomy lab equipment is manufactured in India by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

Because the globe is transparent, students can look through it from the Earth’s point of view and relate what they see on the model to the real sky. Turning the sphere on its support shows the apparent daily rotation of the heavens: stars near the celestial pole circle without setting, while those near the celestial equator rise and set. The marked equator and meridians give a concrete picture of declination and right ascension, the sky’s equivalents of latitude and longitude.

With the horizontal plane set for the school’s own latitude, the teacher can show why the pole star stands at the same height above the horizon as the observer’s latitude, and why the Sun’s path changes through the year. The model links geography lessons on the Earth’s axis with physics and astronomy club work, and it pairs naturally with geography models such as globes and planetaria. Dust it with a soft dry cloth and store it covered to keep the transparent sphere clear.

Manufacturer

Jain Scientific Equipments Private Limited, an educational equipment manufacturer based in Ambala, Haryana, produces this celestial sphere model and sells it under its ScienceLab brand to schools in India and international markets. Find out more on the company profile.

Balance (Product Code: SCL-541/01a) is an equal-arm beam balance with two plastic trays that lets students find the mass of small objects by comparing them against known masses. Science teachers use it to introduce mass, equilibrium and weighing by comparison in middle and secondary classes. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as part of its range of school physics lab equipment in India.

Specifications

Typical Use

Students place the object on one tray and add marked masses to the other until the beam settles level; the total of the masses gives the object's mass, readable to the balance's 0.1 g precision. Before each lesson, set the empty beam level with the balancing mechanism so that every reading starts from a true zero, and keep the combined load within the 200 g maximum to protect the pivot.

The balance works well in practical sessions on density (weigh a sample, then find its volume), on conservation of mass, and on the difference between mass and weight. Used next to a spring dynamometer and other mechanics lab equipment in India, it helps learners see that a balance compares masses directly, while a spring scale measures the pull of gravity as a force.

Manufacturer

This balance is produced by Jain Scientific Equipments Private Limited, the Ambala, Haryana company that trades under the ScienceLab name and builds teaching apparatus for schools, colleges and science distributors. Read more about the company on its company profile page.

Related Lab Equipment

These catalogue items are often ordered with the balance for weighing and equilibrium lessons:

• Set Of Marked Masses — extra hooked masses for the comparison tray or for hanging experiments.
• Weight Box — a boxed set of reference weights for comparison weighing.
• Dynamometer — measures weight as a force in newtons, a useful contrast to weighing by comparison.
• Lever — extends the equal-arm idea to moments at unequal distances from the pivot.
• Triple Beam Balance — an alternative single-pan balance with sliding riders.

See the full Lab Equipment category for more school physics apparatus.

Frequently Asked Questions

What is the capacity and precision of this balance?
It measures up to 200 g with a precision of 0.1 g. For heavier samples, choose a balance with a higher capacity from our catalogue.

Are masses supplied with the balance?
Yes, a marked mass set is included. For the exact pieces in the set, please ask through our contact page before ordering.

How do I set the balance to zero?
With both trays empty, adjust the balancing mechanism until the beam rests level. Recheck this at the start of each class, since moving the balance can shift the zero.

How should the balance be cleaned and stored?
Wipe the plastic trays with a soft, slightly damp cloth and dry them. Store the balance unloaded, with the masses kept together so pieces are not lost.

Can a calibration certificate be provided?
Please discuss calibration-certificate availability with our team via the contact page when you enquire.

What should an institutional quotation request include?
Give the product code SCL-541/01a, the quantity, the delivery address and any tender specification you must match, so we can respond accurately.
