Vernier Travelling Microscope Manufacturer,Supplier and Exporter in India

Vernier Travelling Microscope (Product Code: SLE/M/132) is a measuring microscope mounted on vernier-scaled horizontal and vertical slides, used to measure very small lengths in college and school physics practicals. Its heavy cast iron base with three levelling screws carries slides with 180 mm horizontal and 140 mm vertical travel, read to 0.02 or 0.01 mm. This physics lab instrument is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Travelling Microscope Used For?

A travelling microscope measures lengths too small or delicate for a ruler or caliper: the bore of a capillary tube in surface-tension experiments, the diameters of Newton's rings, the real and apparent depth of a glass slab for refractive index, and the width of fine wires or slits. The microscope is focused on one edge of the feature and the scale is read, then it is traversed to the opposite edge and read again; the difference between the two readings is the length.

Level the base with the three levelling screws before starting, and lock each slide with its clamping screw once it is roughly in place so the reading cannot drift. Approach every final setting from the same direction to avoid backlash, and read the vernier with your eye square to the scale. Because the microscope can be clamped vertically or horizontally, one instrument covers both depth readings and horizontal width readings.

What to Specify When Ordering

• Vernier least count: 0.02 mm or 0.01 mm
• The number of instruments, for example one per practical station
• Experiment accessories you need, such as capillary tubes or a capillary rise apparatus

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this travelling microscope. The company manufactures it at its licensed factory at Saha, Ambala, Haryana, so colleges, schools, dealers and importers in India and international markets buy it factory-direct rather than through a trader. Quotations, repeat orders and questions about replacement parts are handled by the manufacturer itself. Our company profile gives more background.

Frequently Asked Questions

What is the least count of the Vernier Travelling Microscope?
The Vernier Travelling Microscope (SLE/M/132) is offered with a vernier reading of 0.02 mm or 0.01 mm on its horizontal and vertical scales. State which least count you need when ordering, as it sets the precision of every measurement taken with the instrument.

How far do the slides of the travelling microscope move?
The slides of the Vernier Travelling Microscope travel 180 mm horizontally and 140 mm vertically. Each carriage can be clamped at any position with a clamping screw, and the vertical slide is mounted on the horizontal carriage.

Which experiments use the Vernier Travelling Microscope?
The Vernier Travelling Microscope is used to measure capillary tube bore for surface tension, Newton's ring diameters, real and apparent depth for refractive index, and the width of fine wires or slits. Any small length that can be focused on and traversed can be measured.

Can the microscope be used horizontally?
Yes. On the Vernier Travelling Microscope, the rack-and-pinion microscope on the vertical carriage can be clamped in a vertical or a horizontal position. Horizontal viewing suits objects held upright, such as a capillary tube clamped in a stand.

How is the Vernier Travelling Microscope levelled and stored?
The Vernier Travelling Microscope has a heavy cast iron base with three levelling screws, used to set it level before readings. It comes in a polished wooden case that protects the slides, scales and achromatic optics between practical sessions.

Who manufactures the Vernier Travelling Microscope?
Jain Scientific Equipments Pvt Ltd (ScienceLab) is the OEM manufacturer of the Vernier Travelling Microscope, producing it at its licensed factory at Saha, Ambala, Haryana, India. Schools, colleges, dealers and importers in India and international markets buy it direct from the manufacturer.
