Gas sensing is becoming more and more important in our society due to the need to identify toxic gases quickly and organic vapors for environmental and human security, emission control, and the industry sector. A testing chamber is necessary to examine the fabricated sensing device for high sensitivity and the selectivity of the target analytes under different conditions like a mixture of gases and temperatures. The process gas is mixed in the primary chamber, and through a selective gas separating membrane, a particular gas is allowed for sensing. Typically, gas concentration is determined by analyzing references levels, measured in standard dry air conditions.
EQ-PCE-66 is a compact Ultraviolet (UV) Ozone cleaner, which is a dedicated system to remove a variety of contaminants from surfaces of substrates samples. UV Ozone cleaning is simple to use the dry process which is a highly effective method to clean surfaces. The cleaning effect is caused by irradiating the surface of a substrate with suitable lamps creating enough energy in the UltraViolet spectrum range. It is the photo-sensitized oxidation process by atomized Oxygen and high reactive Ozone. The UV radiation directly to the surface stimulates the reaction. Volatile hydrocarbon products are produced. The removal of hydrocarbons in nanometer thickness by oxidation results in ultra-clean surfaces with significant wettability. This is very important before the thin-film coating process of glass and ceramic surfaces.

The DMA results can be correlated with the molecular structure and helps in evaluating other material properties like glass transitions, crystallinity, crosslinking effects, fatigue and other time dependent effects. It can handle a variety of samples ranging from thermoplastics, thermosets, elastomers/rubbers, to some of the metals.
The bottom pouring type stir casting instrument (SwamEquip, India) is used for melting and fabrication of metal matrix composites in a permanent split type steel mould under vacuum condition. The melting and pouring can be done under inert gas protected environment to prevent oxidation of the metal in its molten state. The motor operated stirring helps in proper alloying/mixing of added constituent materials with uniform dispersion.
Due to the partly elastic nature and very high viscosity of polymers, power intensive sturdy machinery like internal mixers is necessary to achieve the mixing of additives into the polymer. Internal mixers help in production compounds of polymers. Machine consist of a chamber with two rotors, capable of generating high shear forces, which disperses the fillers and other raw materials in the polymer. The generation of these shear forces results in the production of a uniform, quality compound. After a defined mixing period, the compound is dropped onto a mill or extruder where mixing is completed.
Compression Moulding is a matched metal tool generally Consist of a heated press to consolidate sheet materials or moulding compounds at relatively high pressures. The mold is closed with a top plug and compressed with large hydraulic presses in order to have the material contact over all areas of the mould. It is widely used to produce sandwich structures that incorporate a core material such as a honeycomb or polymer foam. Composites processed by compression moulding commonly include thermosetting prepregs, fibre-reinforced thermoplastic, etc. The material to be moulded is placed in open heated mould cavity. Once the material has been positioned in the tool, the press is closed and the material is allowed to either cure or consolidate. Finally, tool can be opened and the part is removed.
High temperature tube furnace (Carbolite Gero) with maximum operating temperature of 1800 °C and programmable temperature controller, provides excellent temperature uniformity. The heating can be done under ambient, vacuum, or inert gas atmosphere. The tube furnace is used for synthesis, sintering, annealing, calcination, tempering, degassing, ageing, etc of various types of materials.
Muffle furnace is used to heat the material to significantly high temperature while maintaining it totally isolated from external substances and contaminants. The lining of muffle furnace is done with stainless steel which makes it largely corrosion protected. The temperature range of furnace can be reached upto 1000 °C. The heating process to desired temperatures is done by conduction, convection and blackbody radiation from electrical resistance heater elements. Therefore, there is no combustion involved in the temperature control of the system which allows for much greater control of temperature uniformity and assures isolation of the material being heated from the by-products of fuel combustion.
High-energy ball milling is a ball milling process in which a powder mixture placed in a ball mill is subjected to high-energy collisions from the balls. High-energy ball milling is a mechanical deformation process that is frequently used for producing nanocrystalline metals or alloys in powder form. This process has been successfully used to produce metals with minimum particle sizes from 4 to 26 nm. This device is equipped with an automatic hood lock.

The combination of high-frequency impact grinding, intense friction and circular jar movements ensures an unprecedented grinding performance. The grinding jar supports are each mounted on two discs, which rotate in the same direction, thus moving the grinding jars on a circular path without changing their orientation. The interplay of jar geometry and movement mechanics causes strong friction between the grinding balls, the sample material and the jar walls, as well as high acceleration, which allows the grinding balls to hit the sample material with a strong impact at the curvatures of the jars. This results in a significantly better mixing of the particles with a higher final fineness and a narrower particle size distribution.
pH meter, electric device used to measure hydrogen-ion activity (acidity or alkalinity) in solution. It employs a voltmeter attached to a pH-responsive electrode and a reference (unvarying) electrode. When the two electrodes are immersed in a solution, they act as a battery.
A hot air oven is the most common method of sterilization in the laboratory working on dry heat. It consists of an insulated chamber surrounded by an outer case containing electric heaters, a fan, shelves, thermostat, door locking controls. It is used in sterilization of articles that withstand high temperature and do not get burned e.g. Glass-wares, powders, forceps, scissors, scalpels, glass syringes, pharmaceutical products like liquid paraffin, fats, grease, and dusting powder, etc.
It is an indirect sonication method in which a water bath is used. In bath sonication, ultrasonic energy is transmitted to a water bath and then into a vessel or multiple sample tubes. This method is most effective for very small samples.
It is a powerful ultrasonic processor featuring programmable operation and a digital display of operating parameters. Applications include nanoparticle dispersion, creating emulsions, cell lysis and homogenization. A sonicator is made up of three major components: generator, converter and probe. They create a chain-reaction to deliver ultrasonic energy for the desired result. The generator provides power, in the form of electronic pulses, to the sonicator. The converter transforms these pulses into mechanical vibrations, fed into the probe which rests in the sample medium. The probe allows location targeting for exacting results.
A centrifuge is a laboratory device used to separate particles suspended in a liquid according to particle size and density, viscosity of the medium, and rotor speed. Separation is achieved by spinning a vessel containing material at high speed; the centrifugal force pushes heavier materials to the outside of the vessel. Within a solution, gravitational force will cause particles of higher density than the solvent to sink, and those less dense than the solvent to float to the top. The speed of rotation (RPM- revolutions per minute), time and temperature in the centrifuge can be controlled by the user as per the requirement.
A magnetic stirrer is a laboratory device that employs rotating magnetic field to move a stir bar around in liquid samples. The movement of this stir bar mixes the sample thoroughly with rapid movement and agitation. The speed of the magnetic field is controlled by the user, so it can be customized to the specific sample that's being stirred.
