Millikan Oil Drop Apparatus

Approx Price: Rs 9,800 / Piece 

Millikan Oil Drop Apparatus

The Millikan Oil Drop Experiment is one of the most popular experiments in undergraduate physics for several reasons:

·         the experimental principle is straight-forward and easy to understand;

·         it measures a fundamental atomic constant using a method that won its originator, Robert Millikan, the Nobel Prize;

·         the observation of the effects of one or more electrons upon oil drops in an electric field provides a striking demonstration of the quantized nature of electricity.

Clear droplet observation and low droplet drift are essential for success with Millikan’s classic experiment.
Accuracy in the Oil Drop Experiment depends on the student’s ability to accurately measure all the variables involved: plate voltage, plate separation, time and distance of droplet rise and fall, temperature, oil density, etc. Extreme care taken in the design and manufacture of this unit ensures that the student’s best efforts will be rewarded with more accurate results.

 Minimum Electric Field Distortion--A 0.5 mm diameter droplet entry hole in the top capacitor plate has a negligible effect on the electric field.

·         Droplet Hole Cover -- Prevents additional droplets from entering the chamber once the experiment has started.

·         Polished Surfaces -- Polished surfaces on the plate spacer minimize absorption of light (and heat) through the chamber walls.

·         Electrical Connection -- Electrical connection to the top plate.

Easy Cleaning -- The condenser system easily disassembles for cleaning and inspection

Constant-Volume Gas Thermometer and the Absolute Temperature Scale

The temperature readings given by a gas thermometer are nearly independent of the substance used in the thermometer. One version is the constant-volume gas thermometer . The physical change exploited in this device is the variation of pressure of a fixed volume of gas with temperature. When the constant-volume gas thermometer was developed, it was calibrated by using the ice and steam points of water, as follows (a different calibration procedure, which we shall discuss shortly, is now used): The flask was immersed in an ice bath, and mercury reservoir B was raised or lowered until the top of the mercury in column A was at the zero point on the scale. The height h, the difference between the mercury levels in reservoir B and column A, indicated the pressure in the flask at 0°C.

In recent years Magnetic Resonance has developed into a very useful and powerful tool in solid state research. In this method, use is made of the Zeeman interaction of the magnetic dipoles associated with the nucleus or electron, when placed in an external magnetic field. Accordingly, they are identified as NMR (Nuclear Magnetic Resonance) or ESR (Electron Spin Resonance). This form of spectroscopy finds many applications in the investigation of crystal structures, environmental effects, dynamic effects, defects in solids and in many diverse branches of Physics, Chemistry and Biology.

Elementary Magnetic Resonance

·         DE = (gµ0H)mj

·         DE = gµ0H 0r = hn0

Experimental Technique

I sec, we get 2.8MHz/gauss

Basic Circuit

The first stage of the ESR circuit consists of a critically adjusted (marginal) radio frequency oscillator with 4-digit frequency display. This type of oscillator is required here, so that the slightest increase in its load decreases the amplitude of oscillation to an appreciable extent. The sample is kept inside the tank coil of the oscillator, which in turn, is placed in the 50Hz magnetic field, generated by the Helmholtz coils. At resonance, i.e. when the frequency of oscillation equal to the Larmour’s frequency of the sample, the oscillator amplitude registeres a dip due to the absorption of power by the sample. This obviously, occurs periodically four times in each complete cycle of the supply voltage. The result is an amplitude modulated carrier which is then detected using a FET demodulator and amplified by an op-amp circuit.

Highly stabilised and almost ripple free power supply for the above circuit is obtained using an integrated circuit regulator.

Phase Shifter

This can compensate the undermined phase difference which may be introduced in the amplification stages of the spectrometer and oscilloscope.

50Hz Sweep Unit

A 50Hz current flows through Helmholtz coils which provides a low frequency magnetic field to the sample. As the resonance is observed at few gauss only, no static magnetic field is applied.

An auxanometer is an apparatus for measuring increase or rate of growth in plants.

In case of an arc-auxanometer  there is a wire fixed with the plant apex on one end and a dead-weight on the other. It passes over a pulley which has a pointer attached to it. When the plant's height increases, the pulley rotates and the pointer moves on a circular scale to directly give the magnitude of growth.

Reversible Pendulum Kater's

Approx Price: Rs 1,750 / pcs 
The pendulum consists of a rigid metal bar with two pivot points, one near each end of the bar. It can be suspended from either pivot and swung. It also has either an adjustable weight that can be moved up and down the bar, or one adjustable pivot, to adjust the periods of swing. In use, it is swung from one pivot, and the period timed, and then turned upside down and swung from the other pivot, and the period timed. The movable weight (or pivot) is adjusted until the two periods are equal. At this point the period is equal to the period of an 'ideal' simple pendulum of length equal to the distance between the pivots. From the period and the measured distance between the pivots, the acceleration of gravity can be calculated with great precision from the periodicity equation for a simple pendulum

Micrometer Screw Gauge

Approx Price: Rs 155 / pcs 

Micrometer screw gauge, is a device incorporating a calibrated screw widely used for precise measurement of components in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers. Micrometers are usually, but not always, in the form of calipers (opposing ends joined by a frame), which is why micrometer caliper is another common name. The spindle is a very accurately machined screw and the object to be measured is placed between the spindle and the anvil. The spindle is moved by turning the ratchet knob or thimble until the object to be measured is lightly touched by both the spindle and the anvil.

Micrometers are also used in telescopes or microscopes to measure the apparent diameter of celestial bodies or microscopic objects.

Ranges are 10 mm, 15 mm,20,25 mm x1/100 mm


Approx Price: Rs 125 / pcs 

Spherometer is an instrument for the precise measurement of the radius of a sphere. Originally, these instruments were primarily used by opticians to measure the curvature of the surface of a lens.

The usual form consists of a fine screw moving in a nut carried on the centre of a small three-legged table or frame; the feet forming the vertices of an equilateral triangle. The lower end of the screw and those of the table legs are finely tapered and terminate in hemispheres, so that each rests on a point. If the screw has two turns of the thread to the millimetre the head is usually divided into 50 equal parts, so that differences of 0.01 millimetre may be measured without using a vernier. A lens, however, may be fitted, in order to magnify the scale divisions. A vertical scale fastened to the table indicates the number of whole turns of the screw and serves as an index for reading the divisions on the head.

A contact-lever, delicate level or electric contact arrangement may be attached to the spherometer in order to indicate the moment of touching more precisely than is possible by the sense of touch. To measure the radius of a sphere—e.g. the curvature of a lens—the spherometer is levelled and read, then placed on the sphere, adjusted until the four points exert equal pressure, and read again. The difference gives the thickness of that portion of the sphere cut off by a plane passing through the three feet.

Vernier Caliper

Approx Price: Rs 45 / pcs 

The Vernier caliper is an extremely precise measuring instrument; the reading error is 1/20 mm = 0.05 mm.

Close the jaws lightly on the object to be measured.

If you are measuring something with a round cross section, make sure that the axis of the object is perpendicular to the caliper. This is necessary to ensure that you are measuring the full diameter and not merely a chord.

Ignore the top scale, which is calibrated in inches.

Use the bottom scale, which is in metric units.

Notice that there is a fixed scale and a sliding scale.

The boldface numbers on the fixed scale are centimeters.

The tick marks on the fixed scale between the boldface numbers are millimeters.

There are ten tick marks on the sliding scale. The left-most tick mark on the sliding scale will let you read from the fixed scale the number of whole millimeters that the jaws are opened.
