Description: Highly Sophisticated infrared spectroscopy system with Diamond ATR helps in non-destructive sample analysis and resolution 0.5 cm-1.

Rheometer

Make: Anton Paar

Model: MCR 72 Rheometer

Description: Rheometer is used to measure the way in which a liquid, suspension or slurry flows in response to applied forces. It is used for those fluids which cannot be defined by a single value of viscosity and therefore require more parameters to be set and measured than is the case for a viscometer. It measures the rheology of the fluid. A Rheometer is capable of measuring viscosity and elasticity of non-Newtonian materials under a wide range of conditions.

Polarizing Optical Microscope

Make: Olympus, Japan

Model: BX53

Description: The polarizing microscope is particularly useful in the study of birefringent materials such as crystals and strained non-crystalline substances. It is widely used for chemical microscopy and optical mineralogy. Some specific uses are

1. To determine the angular orientation and rotational mobility of fluorescent molecules.
2. Visualize birefringent or double-refractive structures.
3. Texture morphologies of liquid crystals and polymeric materials.
4. Surface defects and topography.

UV-Vis spectrophotometer

Make: Perkin Elmer, Singapore/ USA

Model: Lambda 365

Description: Spectrophotometry is a procedure for determining how much light is reflected by a chemical material by measuring the strength of light as a light beam travel through the sample solution. The fundamental theory is that light is absorbed or emitted over a certain wavelength spectrum by each compound. Some specific uses are

1. Detection of Impurities
2. Structure elucidation of organic compounds
3. Quantitative determination of compounds
4. Kinetics of reaction

Impedance Analyser

Make: Wayne Kerr

Model: 4100 series

Description: To measure capacitance as a function of frequency from 20Hz to 1MHz, and temperature (from Room temperature to 500oC).

Ferroelectric Tester

Make: Marine India Pvt. Ltd.

Model: 20 PE 1kHz 0.01M

Description: To test the ferroelectric nature of the bulk materials at different temperature

Goniometer (Contact-angle meter)

Make: Rame-Hart Instruments Co.

Model: 90 Pro

Description: The polarizing microscope is particularly useful in the study of birefringent materials such as crystals and strained non-crystalline substances. It is widely used for chemical microscopy and optical mineralogy. Some specific uses are

1. Model 90 CA Edition includes the proven DROP image CA software package.
2. This amazingly easy-to-use software includes tools for calibration and measuring contact angle.
3. The red line option allows the needle or tip to be filtered out of the image prior to analysis.
4. Contact angle measurements can be made on live or saved images.

Poling Unit

Make: Marine India Pvt. Ltd.

Model: 12DC Poling Unit

Description: Polycrystalline ceramics are required to be poled under application of external DC electric filed. It is necessary for piezoelectric studies of piezoelectric samples.

Spin Coater

Make: Apex, India IR

Model: Spin NXG-P1A

Description: Spin coating is a technique used to spread uniform thin films on flat substrates by centrifugal force. The apparatus used for spin coating is called a spin coater, or a spinner. A solution of material is dispensed onto the centre of a wafer, which is then rotated at high speed. Specific use is

1. Deposit uniform thin/thick films on the flat substrates.

Brookfield Viscometer

Make: Brookfield

Model: LVDV-1 HP

Description: Brookfield viscosity is used for viscosity measurement. There are several models of viscometer available from Brookfield. The viscometer motor rotates the spindle at a defined speed (measured in rpm) or shear rate and the viscometer measures the resistance to rotation and reports a viscosity value. Various spindle designs can be employed, depending on the nature of the sample and the requirements the most used spindles are disks and T-bars (RV and T-types in Brookfield manuals. Brookfield viscometers work as any strain-controlled rheometers since they apply angular velocity and measure torque

High Performance Liquid Chromatography(HPLC)

Make: Agilent

Model: 1120 Compact LC

Description: High Performance Liquid Chromatography which is also known as High Pressure Liquid Chromatography. It is a popular analytical technique used for the separation, identification and quantification of each constituent of mixture. HPLC is an advanced technique of column liquid chromatography. The solvent usually flows through column with the help of gravity but in HPLC technique the solvent will be forced under high pressures upto 400 atmospheres so that sample can be separated into different constituents with the help of difference in relative affinities. In HPLC, pumps will be used to pass pressurized liquid solvent including the sample mixture which is allowed to enter into a column filled with solid adsorbent material. The interaction of each sample component will be varies and this causes difference in flow rates of each component and finally leads to separation of components of column.

Refrigerated Centrifuge

Make: Remi

Model: CPR-24 I Plus 365

Description: Refrigerated centrifuges are the centrifuges that are provided with temperature control ranging from -20°C to -30°C. These centrifuges provide the RCF of up to 60,000 xg that is ideal for the separation of various biological molecules. These are typically used for collecting substances that separate rapidly like yeast cells, chloroplasts, and erythrocytes. The chamber of refrigerated centrifuge is sealed off from the outside to meet the conditions of the operations.

Universal Testing Machin (UTM)

Make: Aimil

Model: AIM-653-1

Description: UTM machine is also known as UTM tester, materials testing machine, or material testing frame and that’s why manufacturers gave a common name `Universal testing machine’ and this machine used to test the tensile strength and compressive strength of materials. And other mechanical properties like tension, exerting tensile, and compression or transverse stresses. Also gives different tests like peel test, flexural test, tension test, bend test, fiction test, spring test, etc. UTM machines have different roles stripped of capabilities or marketed for specific industries & sectors which play unique roles in the development of infrastructure, roads, and highways. UTM is one of the best multi-purpose equipment for R&D labs or the QC department.
