Travelling Microscopes
We are renowned as one of the preeminent Travelling Microscopes Manufacturer & Exporters from India. The Travel Lab Microscopes offered by us includes a heavy cast iron base fitted with three leveling screws with the top machined over which slides a gun metal carriage. A microscope tube is attached with a 10x Ramsaden Eye Piece with cross line graticule & an Achromatic 2"or 3" focal length objective of high quality. The Motorized Traveling Microscopes travel 17 cms horizontally and 14 cms vertically and guarantees accurate vernier reading 0.02 or 0.01 mm. with swing out magnifier for reading vernier.

Laboratory Spectrometer offered by us are extensively demanded in the market due to its robust structure that includes telescope & collimator that have fine rack & pinion motion and are mounted on a stable heavy C. I. base with three leveling screws. Customers are eased with the availability of the Student Spectrometer in Brass and Stainless Steel Scale in both the sizes of 15.0 cm (6") and 17.5 cm (7") of protected circle. Moreover, we are listed at the apex in the list of the preeminent Scientific Spectrometer Suppliers in India.

Newton's Ring Microscope

We are well-established as one of the trusted Newton's Ring Standard Microscope Manufacturers & Exporters in India. The Newton's Ring Microscope offered by us is extensively demanded in the market as no alternative is available in terms id quality and performance. Moreover, some of the key features of the Newton's Ring Apparatus, offered by us, are as mentioned below :

•Compact instrument with full arrangements for conducting Newton's Ring experiment.

•A standard microscope unit with 30x magnification and rotatable cross line eye piece.

•Focusing of microscope is through Rack and Pinion.

•Longitudinal movement of 26 mm is done by rotating the drum provided which reads up to 0.001cm.

•Complete with optical glass and convex lens inside a metal case.

•Packed in a sturdy wooden box along with all standard accessories.

Power Rheostats are made with a variety of resistance & current carrying capacity so as to satisfy every need. They are wound with heavily oxidized eureka resistance wire upon a porcelain tube dia 44 mm aprox. The tube is carrying upon Bakelite rider and the heavy duty sliding contact is of the phosphor bronze with brass rod. 4 mm socket terminals are fitted, allowing for rheostat or potentiometer connection. Total resistance and maximum current capacity is marked on the slider. Total Permanent current loading should not exceed 75% of the marked values. The actual resistance of Wire Wound Rheostats shall be +20% -5% of the rated resistance as per our resistance chart. (as per ISI specification no. IS : 9051 S. No. 10.3), we are recognized as one of the major Electronic Rheostats Manufacturers and Exporters from India.
