5 Water Distillation Plant

Water Distillation System is the plant in which heat is provided to boil impure form of water into steam which is reduced back into water and then collected in a pure form of water. When water boils, it leaves left impurities behind in the boiling chamber.

6 Water Bath

water bath is laboratory equipment made from a container filled with heated water. It is used to incubate samples in water at a constant temperature over a long period of time. All water baths have a digital or an analogue interface to allow users to set a desired temperature. Utilizations include warming of reagents, melting of substrates or incubation of cell cultures. It is also used to enable certain chemical reactions to occur at high temperature. Water bath is a preferred heat source for heating flammable chemicals instead of an open flame to prevent ignition. Different types of water baths are used depending on application. For all water baths, it can be used up to 99.9 °C. When temperature is above 100 °C, alternative methods such as oil bath, silicone bath or sand bath may be used.

7 Film Applicator

 A film applicator is a device used to evenly spread a substance, such as polymer, ink, or cosmetics, over a substrate such as a drawdown card.

Applicators are usually metal bars that are manufactured to high tolerances to give consistent, repeatable results. Each bar will give a "theoretical wet film thickness" or, in other words, the thickness of the coating that should remain on the drawdown card after application. Even with high manufacturing tolerances, the actual wet film thickness can vary from 50% to 90% of the gap.

List of Equipments: - This laboratory is equipped with the following equipments
Sr. No. Equipment General Description Picture
1 Fourier Transform Infrared Spectroscopy (FTIR) with ATR attachment

Fourier Transform Infrared Spectroscopy (FTIR) spectroscopy offers a vast array of analytical opportunities in academic, analytical, QA/QC and forensic labs. FTIR offers quantitative and qualitative analysis of organic and inorganic samples. FTIR identifies chemical bonds in a molecule by producing an infrared absorption spectrum. FTIR is an effective analytical instrument for detecting functional groups and characterizing covalent bonding information. The spectrum can provide the range of information such as,

  • Most commonly, the identification of an unknown polymer.
  • Quantitative information, such as additives or contaminants.
Kinetic information through the growth or decay of infrared absorptions.

2 Differential Scanning Calorimetry (DSC)

Differential Scanning Calorimetry DSC is a thermoanalytical technique used for polymers in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. Both the sample pan and reference pan are maintained at nearly the same temperature throughout the experiment. DSC can be used to measure thermal properties of a polymeric material. Using this technique, it is possible to observe fusion and crystallization events as well as glass transition temperatures Tg. DSC can also be used to study oxidation, as well as other chemical reactions. 

3 Gel Permeation Chromatography (GPC) 

Gel Permeation Chromatography (GPC) separates analytes on the basis of size. The technique is often used for the analysis of polymers. Polymers can be characterized by a variety of definitions for molecular weight including the number average molecular weight (Mn), the weight average molecular weight (Mw), the size average molecular weight (Mz), or the viscosity molecular weight (Mv).

4 Rheometer

Rheometer is a precision instrument that contains the material of interest in a geometric configuration, controls the environment around it, and applies and measures wide ranges of stress, strain, and strain rate. It is a device used to measure the way in which a polymeric liquid, suspension or slurry flows in response to applied forces. 

5 Melt Flow Index (MFI) Apparatus

Melt flow index (MFI) is defined as the mass of polymer, in grams, flowing in ten minutes through a die of a specific diameter and length under pressure applied via prescribed alternative gravimetric weights for alternative prescribed temperatures. It is an indirect measure of molecular weight, with high melt flow rate corresponding to low molecular weight. This equipment provides understanding about the melt flow of material so that an engineer can choose a polymer that has MFI enough to be easily gain a shape from molten polymer.

6 Melting Point Apparatus

This instrument is used to determine the melting point of a substance, and the melt can be easily viewed via a magnifying lens with built-in illumination. The temperature increases, phase changes occurred in the sample from solid to liquid. Students can records the temperature range starting with the initial phase change temperature and ending with the completed phase change temperature.

The temperature range that is determined can then be averaged to gain the melting point of the sample being examined.
