Laboratory Trolley (Product Code: SLE/HF/26) is a chemical-resistant polymer trolley that weighs just 13.7 kg yet carries a rated load of 250 kg, rolling on 100 mm castors with two brakes. It stands 1020 mm high and gives a 680 x 450 mm shelf area for moving bottles, sample racks, glassware and instruments around research, medical, industrial and education labs. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a laboratory equipment manufacturer in India with trolleys in several configurations.

Specifications

Typical Use

Research groups use the trolley to move a morning’s samples from the receiving bench to the instrument room, or to carry media bottles and racks between a preparation area and a laminar flow cabinet. Its low 13.7 kg weight makes it easy to push, lift over a step or reposition when a lab is rearranged, and the two braked 100 mm castors keep it in place when parked beside a bench.

Because it ships in a compact 800 x 510 x 290 mm pack and is assembled on site with the supplied rubber mallet, it is a practical choice when stocking lab equipment for research in India at locations far from the supplier. Keep loads within the 250 kg rating, place bottles in racks or trays so they cannot roll, and wash the polymer shelves with water and a mild detergent after any spill.

Manufacturer

The trolley is part of the ScienceLab catalogue of Jain Scientific Equipments Private Limited, whose base is in Ambala, Haryana; the company serves teaching, testing and hospital laboratories. See the company profile for more about us.

Laboratory Trolley – 4 Shelf (Product Code: SLE/HF/27) is the tallest trolley in this polymer series: four 680 x 450 mm trays spaced 170 mm apart within an overall height of 1080 mm, giving plenty of level space for many small, low items at once. It is used in research, medical, industrial and education labs to move sample racks, boxed consumables, bottles and small instruments. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a laboratory equipment exporter from India that supplies teaching and testing laboratories at home and abroad.

Specifications

Typical Use

Four close-set trays suit workflows with lots of small, flat loads: a microbiology lab can separate fresh media, inoculated plates and used material onto different tiers, and a clinical or QC lab can sort sample racks by batch or by instrument. Keeping categories on separate trays reduces mix-ups when the trolley is shared between several people.

Many labs also use it as a mobile alternative to a fixed lab storage cabinet in India’s crowded teaching labs, parking it by a bench during a session and wheeling it away afterwards. With only 170 mm between trays, reserve the top tray for taller items, keep heavy loads low, respect the 250 kg working load, and apply the two brakes before loading.

Slotted Mass Hanger, 1kg (Product Code: SLE/LB/28) is a large format cast hanger, weighing 1kg itself, used to carry large slotted masses in heavy-load physics experiments such as wire stretching, beam loading and pulley work. It is sold as the hanger only, 26cm long and 7cm wide, so college and senior-school departments can replace a lost hanger or add one to existing masses. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the 1kg Slotted Mass Hanger Used For?

College and senior-school physics labs use a 1kg hanger where loads rise in kilogram steps: hanging it from the wire of a Searle’s Young’s modulus apparatus, from the centre of a loaded beam, or from the free end of a cord running over a bench pulley. Because the hanger already contributes 1kg, students start their table of readings at that value and add large format slotted masses to reach higher loads without building a tall, unstable stack of small pieces.

Heavy hangers call for care: hang the hanger from a firmly clamped support, keep hands and feet out from under the load, and lower each slotted mass onto the stem gently instead of dropping it. Turning the slots of successive masses in different directions helps keep the stack balanced during mechanics practicals.

What to Specify When Ordering

• The hanger size: this 1kg hanger (26cm x 7cm) or the lighter Slotted Mass Hanger, 500g for smaller starting loads.
• Whether you also need large format slotted masses, since this listing is for the hanger alone.
• The number of hangers per laboratory and the delivery address.

OEM Manufacturer

The Slotted Mass Hanger, 1kg is made by Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) that trades as ScienceLab, at its own licensed factory at Saha, Ambala, Haryana, India. Because the hanger comes direct from its manufacturer, colleges, institutions, dealers and importers can combine it with other mechanics apparatus in one factory quotation, and repeat orders for extra hangers go back to the same source — simply ask us. Learn more on our company profile.

Related Laboratory Equipment

Items used with a 1kg slotted hanger in heavy-load experiments:

• Apparatus Young Modulus Searle’s — a classic wire-extension practical where kilogram loading steps are used.
• Pulley, Bench Mounting, Ball Bearing — lets the loaded hanger pull a cord over the bench edge.

No. The Slotted Mass Hanger, 1kg is sold as the hanger only, and the large format slotted masses that stack on it are ordered separately. Mention the masses in the same enquiry if you need a complete loading set.

How much does the hanger weigh, and how big is it?
The Slotted Mass Hanger, 1kg weighs 1kg on its own and measures 26cm long by 7cm wide. Check that your support leaves enough clearance beneath it for the hanger plus the stack of large format masses you plan to add.

Who manufactures the Slotted Mass Hanger, 1kg?
The Slotted Mass Hanger, 1kg is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India, and is supplied factory-direct to colleges, schools, dealers and importers in India and international markets.

Slotted Mass Hanger, 500g (Product Code: SLE/LB/29) is a large format cast hanger of 500g, used to carry large slotted masses when a stiff spring, pulley cord or wire needs a half-kilogram starting load in school and college physics laboratories. Sold as the hanger only, it gives finer first steps than a 1kg hanger and suits departments topping up their existing large format masses. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the 500g Slotted Mass Hanger Used For?

A 500g hanger is the usual starting load when a spring or wire would be overstretched by a 1kg first step. Students hang it from a stiff spring on a Hooke’s law stand, from a cord passing over a bench pulley to pull a trolley or block, or from a beam to study deflection, then add large format slotted masses in turn and record each new total. It also makes a convenient counterweight in pulley-system demonstrations.

Before the first reading, let the hanger hang still so it does not swing, and read scales at eye level. Keep the supporting clamp tight, add masses one at a time, and remove them in reverse order at the end so the spring or wire relaxes gradually – good habits for any mechanics lab practical involving hanging loads.

What to Specify When Ordering

• The hanger size: this 500g hanger, or the 1kg large format hanger when loads rise in whole kilograms.
• Whether large format slotted masses should be quoted as well, since this listing covers the hanger alone.
• The clearance available below your support, as the listed size is 34cm long and 8cm wide.
• The number of hangers needed and the delivery location.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of the Slotted Mass Hanger, 500g.

Laser Pen, Red (Product Code: SLE/PHY/107) is a lightweight red laser pointer used for ray optics demonstrations and simple diffraction work in school and college physics labs. Teachers also use it as a presentation pointer, and its 0.5 milliwatt beam stays on after one press of the button until it is pressed again. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for users of optics lab equipment in India.

Specifications

What Is the Laser Pen Used For?

A narrow, bright beam makes light paths easy to see. Shone through a glass block or prism resting on paper, the red beam lets students mark incident, refracted and emerging rays; aimed at a plane mirror, it shows the angle of incidence equalling the angle of reflection. Passed through a narrow slit or a pair of slits onto a distant wall, it produces a simple diffraction or interference pattern.

Because the button latches, the pen can be laid on a support and left running while the class takes measurements, and a little chalk dust in the air makes the beam visible in flight. Always follow the caution on the listing: never look into the beam, never point it at anyone's face and keep optical instruments out of its path. Teachers should supervise its use at all times.

Supplier

The Laser Pen, Red is supplied by ScienceLab, the trade name of Jain Scientific Equipments Private Limited, Ambala, Haryana. It is sourced for the company's customers and can be packed with prisms, lenses, mirrors and other optics items, so a school receives its whole optics order from one supplier. See our company profile for more about ScienceLab.

Related Physics Lab Equipment

Items commonly used with the laser pen in optics practicals:

• Prism – Glass Rectangular Block — traces refraction and the sideways shift of the beam.
• Prism, Clear Glass — shows deviation of a single ray through a 60-degree prism.
• Mirror, Plane Glass — demonstrates the law of reflection.
• Semiconductor Laser — an alternative laser source for optics experiments.

More light and optics apparatus is available in our Physics Lab Equipment range.

Frequently Asked Questions

What is the output power of the Laser Pen, Red?
The Laser Pen, Red has a listed power of 0.5 milliwatts. That low output is enough to trace ray paths through blocks, prisms and mirrors in a darkened room, but the beam must still never be viewed directly or aimed at eyes.

Do I need to keep pressing the button?
No. The Laser Pen, Red has a latching button: press it once and the beam stays on until you press it again. This leaves both hands free to position blocks, mirrors or slits and to mark ray paths on paper.

How should the laser pen be used safely in class?
The Laser Pen, Red carries a caution: do not stare into the beam or view it directly with optical instruments. Keep the beam below eye level and away from faces, and let students use it only under teacher supervision during ray optics demonstrations.

What batteries does it use?
The battery type for the Laser Pen, Red is not given in its listing. Please ask through our contact page if you need to know the battery size or want spare batteries included with your order.

Can it be used for diffraction experiments?
Yes, the listing describes the Laser Pen, Red as suitable for simple diffraction work. Shine it through a narrow slit, a pair of slits or a fine grating onto a screen a few metres away to see a pattern of bright and dark bands.

Who supplies the Laser Pen, Red?
The Laser Pen, Red is supplied by Jain Scientific Equipments Pvt Ltd, which trades as ScienceLab from Ambala, Haryana, India. It can be quoted with prisms, lenses and other optics items so your laboratory order comes from one source.

Lenses Cylindrical Glass, Biconcave (Product Code: SLE/PHY/108) is a diverging cylindrical glass lens used to spread rays of light apart in ray-tracing and optics experiments in school and college laboratories. Physics students use it to locate a virtual focus on paper, and it has a listed focal length of 75 mm and dimensions of 50 x 45. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Biconcave Cylindrical Lens Used For?

A cylindrical lens curves in one direction only, so it turns a flat sheet of light from a ray box into a clear fan of rays on paper rather than bringing it to a point. Stood on its edge in the path of parallel rays, this biconcave lens spreads them outwards; tracing the emerging rays backwards with a ruler shows that they appear to come from a virtual focus on the same side as the light.

Measuring from that point to the lens centre gives the focal length, which students can compare with the listed 75 mm. Placed against the biconvex lens of the same series, it makes parallel rays leave nearly parallel, showing that equal and opposite lens powers cancel. As part of a convex and concave lens set for school optics, it should be handled by its edges and returned to its pouch after use.

What to Specify When Ordering

• Lens type — biconcave, biconvex or planoconvex from the same series.
• Number of lenses per student group or class.
• Whether you need the full three-lens series for comparison work.
• A light source such as a laser pen, if your lab has no ray box.

OEM Manufacturer

This biconcave lens is manufactured by ScienceLab, the trading name of Jain Scientific Equipments Private Limited, at the company's own licensed factory at Saha, Ambala, Haryana, India. Because the maker supplies it directly, laboratories and optics dealers can match further lenses of the same series later, with quotations coming straight from the factory. Find out more on our company profile.

Frequently Asked Questions

What is the focal length of the Lenses Cylindrical Glass, Biconcave?
The Lenses Cylindrical Glass, Biconcave has a listed focal length of 75 mm. Because the lens is diverging, this focal point is virtual: students find it by tracing the spread-out rays backwards until they meet on the incoming side.

What are the lens dimensions?
The listing gives the dimensions of the Lenses Cylindrical Glass, Biconcave as 50 x 45 but does not state the unit. If your ray box or lens holder needs an exact fit, please confirm the size with us through the contact page before ordering.

How is the lens packed?
Each Lenses Cylindrical Glass, Biconcave is individually pouched and supplied in a neat presentation case. The pouch protects the finished curved faces from scratches, and the case keeps the lens safe in a school optics cupboard between practicals.

How is a cylindrical lens different from an ordinary spherical lens?
A spherical lens curves in all directions and acts on light around a single point, while the Lenses Cylindrical Glass, Biconcave curves in one direction only. It spreads a sheet of rays into a flat fan, which is ideal for drawing ray diagrams directly on paper.

Who manufactures this biconcave lens?
The Lenses Cylindrical Glass, Biconcave is manufactured by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, the OEM. It is made at the company's own factory at Saha, Ambala, Haryana, India, and supplied factory-direct to institutions, dealers and importers.

Can I order it with the biconvex and planoconvex lenses?

Lenses Cylindrical Glass, Biconvex (Product Code: SLE/PHY/109) is a converging cylindrical glass lens used to bring parallel rays of light to a line focus in optics and ray-diagram experiments. School and college physics students use it to measure focal length directly on paper, and it is listed with a 75 mm focal length and 50 x 45 dimensions. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as optics lab equipment for India.

Specifications

What Is the Biconvex Cylindrical Lens Used For?

With both faces curved outwards, this lens bends a fan of parallel rays inwards so that they cross at a bright focus about 75 mm behind it. Students stand the lens on a sheet of paper, mark the incoming and outgoing rays with a sharp pencil, and measure from the lens centre to the crossing point to find the focal length for themselves.

Moving the light source closer than the focal length shows the rays leaving the lens still diverging, the ray-diagram basis of a magnifying glass. Outer rays usually cross slightly nearer the lens than central ones, giving a visible example of spherical aberration for advanced classes. Keep fingerprints off the curved faces and slide the lens back into its pouch after each practical.

What to Specify When Ordering

• Which lens you need: biconvex, biconcave or planoconvex.
• Quantity per student group or laboratory.
• Whether all three shapes should be quoted for comparison experiments.

OEM Manufacturer

ScienceLab, the brand of Jain Scientific Equipments Private Limited, is the original equipment manufacturer of this biconvex lens and produces it at its licensed factory in Saha, Ambala, Haryana, India. Schools, colleges and optics dealers buy it direct from the maker rather than a reseller, which keeps repeat orders and replacement lenses simple — just ask us. Visit the ScienceLab company profile to learn more.

The full optics range is in our Physics Lab Equipment category.

Frequently Asked Questions

What focal length does the Lenses Cylindrical Glass, Biconvex have?
The Lenses Cylindrical Glass, Biconvex has a listed focal length of 75 mm. Parallel rays entering one curved face converge to a real line focus about that distance behind the lens, which students can mark and measure on paper.

What does the lens come packed in?
The Lenses Cylindrical Glass, Biconvex is individually pouched and supplied in a neat presentation case. This protects the precision-finished faces in transit and gives teachers a tidy way to issue and collect the lens during practicals.

Can the biconvex lens show spherical aberration?
Yes. With a wide fan of parallel rays, the outer rays passing through the Lenses Cylindrical Glass, Biconvex usually cross a little nearer the lens than the central rays. Drawing both crossing points on paper makes spherical aberration easy for students to see.

Lenses Cylindrical Glass, Planoconvex (Product Code: SLE/PHY/110) is a converging cylindrical glass lens with one flat and one curved face, used to focus light and study refraction in physics optics practicals. Students and teachers use it to compare lens shapes and the effect of lens orientation, and it has a listed focal length of 75 mm. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, for school optics experiments.

Specifications

What Is the Planoconvex Cylindrical Lens Used For?

The flat back face makes this lens ideal for showing that orientation matters. Send parallel rays onto the curved face first and they converge to a fairly sharp line focus; turn the lens round so the flat face meets the light and the rays cross over a longer, more spread-out region. Students can record both ray patterns on paper and discuss why optical designers usually point the curved side towards parallel light.

The flat face also sits neatly against a glass block or plane mirror, so the lens can be combined with other components in ray-box experiments. Used with the biconvex and biconcave lenses of the same series, it rounds out a convex and concave lens set for school optics. Handle it by the edges and store it in its pouch and case.

What to Specify When Ordering

• Lens shape — planoconvex, biconvex or biconcave.
• Number of lenses required for each student group.
• Whether the whole three-lens series should be quoted together.

OEM Manufacturer

The planoconvex lens is produced by ScienceLab, which is the trading name of Jain Scientific Equipments Private Limited, at its licensed factory in Saha, Ambala, Haryana, India. The company is a registered MSME enterprise with manufacturing as its major activity (Udyam UDYAM-HR-01-0003714), and its export shipments are handled under Importer-Exporter Code AAECJ8618A (DGFT).
