A teflon spacer near the tips is also provided to keep the probes at equal distance. The whole - arrangement is mounted on asuitable stand and leads are provided for the voltage measurement.
2. Sample
Germanium crystal in the form of a chip (10X9X0.5mm)
3. Oven
It is a small oven for the variation of temperature of the crystal from the room temperature to about 200°C (max.)
4. Four Probe Set-up, VT -02
The set-up consists of three units in the samecabinet.(i) Multirange Digital Voltmeter In this unit, intersil 31⁄2 digit single chip A/D Converter ICL 7107 has been used. It has high accuracy like auto zero to less than 10μV, zero drift of less than 1μV/ °C, input bias current of 10pA max. and roll-over error of less than one count.

Floor Area | 0.75 m x 0.75 m |
Material | Mild Steel |
Power | 500 W |
Voltage | 220 V |
Phase | Single |
Hydrodynamics of Packed Bed the set up is capable to study the loading and flooding characteristics. It is a packed column packed with Raschig Rings where the Air is counter currently fed to column. Liquid holdup in the column increases the weight of column and also reduces the effective porosity of packing. This reduction in porosity decreases the gas velocity, increases the pressure drop and changes the value of mass transfer co-efficient. The water is fed from the top of the column and loading & flooding characteristic are observed on various flow rates of Air and Water.
Scope Of Experimentations:
- To study the loading and flooding characteristics in a packed column
Utilities Required:
- Compressed Air Supply at 2 Bar, 2.5 CFM
- Water Supply and Drain
- Electricity 500 watts, 220 V, 1 Phase
- Floor Area 0.75 m x 0.75 m

Model Name/Number | VT 407 |
I Deal In | New Only |
Country of Origin | Made in India |
Range | 40 to 400 mg/l as COD |
Because of dicromate ions specific oxidant properties, CrO ²-) unique chemical properties it gets reduced to the chromic ion (Cr³+) in COD test.
COD is a defined test, the extent of sample oxidation can be affected by digestion time, reagent stregnth & sample COD concentration.
COD is often used on a measurement of pollutants in waste water & natural water.
To determine COD two methods are useful, the open reflux method is suitable for a wide range of waste water & large sample size is prefferred. Another is the closed reflux method is suitable for smaller quantities. It requires homogenisation of sample. Accurate measurement of sample values as well as reagent volumes and concentration are critical.
