DIP coater with IR dryer
The presence of an Infra-Red dryer in it. Inside the unit there is an infrared heater, which offers a maximum temperature of 200°C from ambient. After each dip, the Infrared heater helps in drying the substrate. It provides uniform heating to the substrate. The temperature is swiftly attained so that the time taken for the dipping process is greatly reduced. The coating thickness can be easily controlled by adjusting the withdrawal rate and the viscosity of the coating solution. Another advantage of this model is that it minimizes the energy consumption as the heater will be activated only after detecting the substrate and hence it can provide the substrate with accurate temperature.

Surface profilometer SJ 310
Stylus profilometers use a probe to detect the surface, physically moving a probe along the surface in order to acquire the surface height. This is done mechanically with a feedback loop that monitors the force from the sample pushing up against the probe as it scans along the surface. A diamond stylus is moved vertically in contact with a sample and then moved laterally across the sample for a specified distance and specified contact force. A profilometer can measure small surface variations in vertical stylus displacement as a function of position. A typical profilometer can measure small vertical features ranging in height from 10 nanometres to 1 millimetre. The height position of the diamond stylus generates an analog signal which is converted into a digital signal, stored, analyzed, and displayed. The radius of diamond stylus ranges from 20 nanometres to 50 μm, and the horizontal resolution is controlled by the scan speed and data signal sampling rate. The stylus tracking force can range from less than 1 to 50 milligrams.
Cost of using the facility: Starts from INR 200
Bioluminometer
Cost of using the facility: Starts from INR 250
The Bioluminometer allows to instantly verify the microbial contamination of a surface or a liquid, with a bioluminescent reaction.It "read" a light signal that is an output from a sampling device that was passed on the contaminated surface or in the water to be analyzed. During the sampling, the sampling device picks up a cellular molecule, I'ATP (adenosine triphosphate) which is present in all living organisms. When I'ATP is placed in contact with the reaction mixture present in the sampling tube (containing luciferin and luciferase), a reaction takes place that leads to the production of light (photons). This light is measured by the luminometer and converted into a numerical value shown on the display. Higher the microbial contamination is, higher the amount of ATP collection was and, consequently, higher the light produced and the value measured by luminometer would be higher.

ADVANCED IMMUNOHAEMATOLOGY AND FLOW CYTOMETRY
PerkinElmerSCIEX, inductively coupled plasma mass spectrometry (ICP-MS) has become the fastest growing trace-element detection technique covering a diverse range of applications. Hurdles in successfully coupling an ICP source to a mass spectrometer were initially overcome with design breakthroughs such as a center-tapped ground coil to minimize plasma potential and eliminate secondary discharge between the plasma and the grounded MS interface. Further evolution of plasma RF generators led to a unique free-running design where impedance changes in the plasma were matched instantaneously through small changes in the frequency with no moving parts. In addition, plasma potential was kept at minimum by electronically balancing the plasma with respect to the ground potential.
