Simple to use power supply specially designed to reduce the risk of damage to the equipment due to accidental change in the output. Delivers both AC and DC output from 1 to 12V in steps of 1V. Provided with a unique tap selection facility to choose the desired output by means of a U-shaped plug in type shorting link, whose free end is inserted in the socket marked as per the output needed. Double wound transformer made from good quality enameled copper wire with high-grade lamination minimizes losses while ensuring continuous trouble free operation and long life. Provided with 4mm shielded socket for earthing connections.

For exploring the charge distribution and charge holding capacity of the different shaped conductors and demonstrate the Gauss' Law relating to distribution of charge and dependence of field strength near a conductor on its radius of curvature. Comprises a hollow brass conductors of different shapes mounted on top of insulated pillar on a base. The conductors are interchangeable on pillars.

Comprising strips of four metals, one each of copper, iron, aluminium and brass fixed in symmetrical fashion, perpendicular to each other, on a circular wooden frame, with the strips meeting at the center. Outer ends of the strips has small recesses for holding paraffin wax.

Telescope vernier reads to 1 min. of arc. A model for student use, with an optical system equivalent to that on more advanced models, thus permitting many quantitative experiments. Graduated disc 127mm diameter, fixed to table, double ended vernier, to read to one min. of arc, attached to telescope. Both telescope & table have fine adjustment screws & release of clamping screw enables coarse adjustments to be made by hand. Telescope & collimator are fitted with 178mm focal length, 32mm clear aperture achromatic objectives & have rack & pinion focusing telescope fitted with 15x Ramsden eye piece & cross line graticule, collimator with adjustable slit, length 6mm, mounting on telescope & collimator permits accurate leveling of axis & squaring of axis of rotation. The spectrometer table, marked with lines to assist positioning of prism & diffraction grating. Complete in hard wood case with following accessories: One prism clamp, one diffraction grating holder, one watchmakers eyeglass, one Tommy bar for adjusting optical axis.

For exploring the Newton's laws of motion, the concept of conservation of momentum, and elastic-inelastic collision of objects in one-dimension. Comprises a pair of wooden trolleys, each carried upon three wheels with ball bearings to minimize friction and a spring loaded exploder plunger with 2 levels of spring compression, which is activated by a trigger knob on top of the trolley. A tough laminated surface mounted on each trolley enables placing of additional masses for increasing the effective weight of the trolley. Velcro pasted at the back end of each trolley enable the study of inelastic collisions.

For reflection, refraction, and color mixing experiments. The light box consists of a light source 12 V, 24 W lamp, producing convergent, divergent or parallel beam. On one end, an adjustable cylindrical convex lens (for parallel beam) On the other end, a triple aperture system for color mixing experiments (lateral aperture are provided with adjustable hinged mirror). All apertures in the box are provided with vertical channels to hold slit plates and color filters. The optical set includes Acrylic Blocks, set of three mirrors, 2 slit black plates, one with three narrow slits at one end and one narrow slit at the other end. Another black plate with four narrow slits at one end, one wide slit at the other end & set of seven mounted color.

Useful for determination of wind speeds. Comprises three light-weight hemispherical plastic cups attached to a central hub through lightweight spokes. Speed of rotation of these cups calibrated on an analog moving coil meter directly to give the wind speed.

Useful for exploring the principle of working of capacitance, and the relationship between charge, voltage and capacitance. Comprises a pair of adjustable circular metal discs of diameter 100mm attached to the insulated handles and is supported on insulated pillars mounted vertically on a base. Another pillar has a clamp for holding glass dielectric plate between the metal discs. The glass plate may be replaced by plates of other material to study the effect of dielectric. End of insulating handles of metals discs carry a 4mm socket for electrical connection.

To illustrate the principle of image formation due to light rays passing through small apertures. Comprising a polished wooden box with a ground glass screen at the rear end and an adjustable sliding front with a hole.

Made of polyethylene, in three different parts. Top portion is fitted with thistle funnel and bulb structure through which dilute acids can be poured to react with metal sulphides in the lower base of the apparatus. Gas evolved collects in the middle dome from where it can be released through a leak-proof stop-cock having self lubricating PTFE plug. Base provided with residual outlet with a screw cap for easy cleaning.

Wooden, suitable for lenses or mirrors up to 75mm diameter. Comprising a wooden black, with a V-shaped groove to hold lenses or mirrors, mounted on a rectangular wooden base. With index mark engraved on either side of the base. Useful tool in optical benches or other optical experiments for securely holding different sizes and types of lenses and mirrors.

An annular metal ring frame of diameter about 125mm, carries an insulating bush at the top, which has circular metal disc electrode about it and a conducting metal strip on the underside. The smaller, lightweight metal strip is pivoted at the center of bigger strip to provide deflection with the charging of electrode. The metal frame also has an earthing terminal at one side. Complete assembly mounted on base.

A complete self-contained apparatus suitable for vacuum physics experiments and applications requiring evacuated space. Transparent jar and pump, both having unbreakable ABS body. Jar provides a robust chamber capable of withstanding full vacuum without danger of implosion or shattering and fitted with a vacuum gauge and vacuum release valve.Arubber gasket ring on the pump base ensures airtight seal with the jar. A manual exhaustion piston pump in the base provides quick and convenient evacuation of the jar.Fitted with electric bell.Note: The exposure or contact of the apparatus to organic solvents or vapours, or to other aggressive chemicals is to be totally avoided. The apparatus is non-autoclavable.

Comprising a layer of resistance wire wound on an insulating, heat resistant tube (porcelain) which is supported by cast metal feet, our rheostats are highly appreciated by our customers. A sliding contact & three 4mm socket terminals are provided, one terminal being connected to the sliding contact & the other two to the ends of the winding, enabling the unit to be used as a Rheostat or potentiometer. We are counted as the principal sliding rheostat manufacturer and among the eminent laboratory rheostats exporters and suppliers from India.
