Experiments
Energy Band Gap Experiment
OBJECTIVES
To find the energy band gaps for different semiconductor diodes and LEDs
PRINCIPLE
At an absolute zero-degree temperature, semiconductors are pure insulators. As the temperature is increased thermal energy creates vibrations in the crystal lattice and a few electrons, which acquire sufficient vibrational energy break their covalent bond, become free, and move to the conduction band. The energy required to rapture the covalent bond is designated as energy gap EG and termed as energy gap or band gap energy.
KEY FEATURES
- Built-In Heater: The heating element is built into the system and is powered by 12V input. The efficient heating mechanism heats the system to the required temperature in a few minutes with a minimum power requirement of 40W.
- Modular Design: The modular design of the setup allows the testing of multiple diodes as well as different LEDs.
- Built-In Voltage and Temperature Probe: All the necessary parameters to be measured are available directly on the setup itself.

Experiments
Faraday Effect Experiment
OBJECTIVES
- Observe the effect of a magnetic field on the plane of polarization of polarized light as it passes through a dispersive medium.
- Measure the Verdet’s constant of a given dispersive material.
PRINCIPLE
When linearly polarized light passes through an optical medium in a region of the strong magnetic field, the plane of polarization of linearly polarized light rotates by an angle. The angle of rotation of plane-polarized light is proportional to the length of the optical medium and component of the magnetic field in the direction of light. The factor of proportionality is medium-specific and is called Verdet’s constant and this effect is known as the Faraday Rotation or Faraday Effect. Discovered by Michael Faraday in 1845, the Faraday effect was the first experimental evidence that light and electromagnetism are related. In the experimental setup, the optical medium is an SF6 glass cube.
KEY FEATURES
- Modular U- Core design with precise optical alignment – U-Core along with pole pieces are designed with the Poka-Yoke principle so that the optical alignment is undisturbed when the pole pieces are moved to accommodate samples of different dimensions.
- Light Sensor- This enables measurement of light intensity which in turn helps in measuring the amount of rotation of plane polarization. The meter reads with a precision of 1 lux. Sensor-based measurements eliminate the errors in values due to simple eyesight measurement. Moreover, it provides the freedom to conduct the experiment at any setting of polarizer-analyzer angles.

Qualitative
Filter Paper, Grade 1: 9µm
Grade 1: 9 μm,Grade 1 filter paper is the most widely used filter paper for routine applications with medium retention and flow rate.
This grade covers a wide range of laboratory applications and is frequently used for clarifying liquids. Traditionally the grade is used in qualitative analytical separations for precipitates such as lead sulfate, calcium oxalate (hot), and calcium carbonate.
It is used for soil analysis and seed testing procedures. In the food industry, Grade 1 is used for numerous routine techniques to separate solid foodstuffs from associated liquid or extracting liquid and is widely used in education for teaching simple qualitative analytical separations.FP-001 -
Qualitative
Filter Paper, Grade 2: 9µm
Grade 2: 9 μm,Grade 2 filter paper is slightly more retentive and having more absorbing power than Grade 1 with a corresponding increase in filtration time. In addition to general filtrations, the extra absorbency is utilized, for example, to hold soil nutrient in plant growth trials. Also used for monitoring specific contaminants in the atmosphere and in soil testing.

Qualitative
Filter Paper, Grade 3: 5µm
Grade 3: 5 μm,Grade 3 filter paper is almost double the thickness of Grade 1 with still finer particle retention and excellent loading capacity; more precipitate can be held without clogging. The extra thickness gives increased wet strength and makes this grade highly suitable for use in Buchner funnels. The high absorbency is particularly valuable when the paper is used as a sample carrier.

Qualitative
Filter Paper, Grade 4: 22µm
GRADE 4: 22 μm,Grade 4 filter paper is a standard grade filter paper used when high flow rates in air pollution monitoring are required and the collection of fine particles is not critical. Grade 4 filter paper is extremely fast filter paper with excellent retention of coarse particles and gelatinous precipitates such as ferric hydroxide and aluminum hydroxide.Very useful as a rapid filter for routine clean-up of biological fluids or organic extracts during analysis. These cellulose filters are used in qualitative analytical techniques to determine and identify materials.

Qualitative
Filter Paper, Grade 5: 2.5-3µm
GRADE 5: 2.5-3 μm,Grade 5 filter paper is a standard grade clarifying filter paper excellent for cloudy suspensions and for water and soil analysis. This grade of filter papers provides maximum degree of fine particle filtration in the qualitative range. Capable of retaining the fine precipitates encountered in chemical analysis. Slow flow rate.
