Travelling Microscope Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-13430
Jlab Export is a leading Travelling Microscope Manufacturer,and suppliers in India
Travelling Microscope (code EL-PL-13430) is a microscope carried on vertical and horizontal vernier scales that each read to 0.01 mm, for measuring small lengths such as the bore of a capillary tube or the apparent depth of a liquid. Rack and pinion focusing, two slow-motion knobs and a reading lens help set it exactly. JLab builds the JL368 on an iron base in Ambala, India.

Taking a Reading to 0.01 mm
Focus on the object with the rack and pinion until the cross-wire and the mark are both sharp, then bring the cross-wire onto the mark with a slow-motion knob. The reading is the main scale value plus the coinciding vernier division multiplied by the least count, 0.01 mm. A length is the difference between two such readings, so approach the second setting from the same side as the first; turning back and forth lets slack in the screw creep into the result. The milky-white sheet on the base gives a plain background for objects on the horizontal stage.
Bore Diameter and Refractive Index
For a capillary, set the cross-wire tangent to one side of the bore, read the horizontal scale, move to the opposite side and read again; the difference is the diameter. For the refractive index of a liquid, the vertical scale gives three readings: a mark on the bottom of an empty container (R1), the same mark seen through the liquid (R2) and a few grains of fine powder floating on the surface (R3). Then n = real depth ÷ apparent depth = (R3 − R1) ÷ (R3 − R2).
