Widely acclaimed as an efficient and effective manufacturer and supplier, we are engaged in Four Probe Setup. The four-point probe method is the most common way to measure a semiconductor material’s resistivity. Two of the probes are used to source current and the other two probes are used to measure voltage. The inner probes draw no current because of the high input impedance voltmeter in the circuit in a four probe apparatus.

Features:

• Leakage-resistant surface
• Digital panel meter
• Constant current generator

Pure alkali halide crystals are transparent throughout the visible region of the spectrum. The crystals

may be colored in a number of ways

(1) by the introduction of chemical impurities

(2) by introducing an excess of the metal ion

(3) by X-ray, g-ray, neutron and electron bombardment

(4) by electrolysis

Colour centres produced by irradiation with X-rays

When a X-ray quantum passes through an ionic crystal, it will usually give rise to a fast photo-electron with an energy of the same order as that of the incident quantum. Such electrons, because of their small mass, do not have sufficient momentum to displace ions and therefore loose their energy in

producing free electrons, holes, excitons and phonons. Evidently these while moving near the vacancies form trapped electrons as well as trapped holes. The trapped-electron or trapped-hole centres so formed can be destroyed (bleached) by illuminating the crystal with light of the appropriate wavelength or warming it.

Thermoluminescence

Important information about the colour centres can be obtained by measuring the changes that occur when a coloured crystal is gradually heated. As the temperature is raised electrons and holes escape from their

traps at an increasing rate. The freed charges can recombine with each other or with other defects and give out luminescence by recombination.

The resulting thermoluminescence or ‘glow’ reaches maximum and then decreases to zero as the supply of trapped electrons or holes becomes exhausted. The plot of luminescence intensity verses temperature, taken

at a constant heating rate, is called the ‘glow curve’. It may contain one or many glow peaks, depending upon whether there are one or several different kinds of traps.

From the glow curve one determine the trap depth; the deeper the trap, the higher the temperature of the glow peak. A correlation between the temperature at which thermoluminescence occurs and the temperature at which particular band bleach can give valuable information about specific

centres. Typical results obtained from this set-up for

KCl crystal are shown in figure.

The experiment consists of the following

These instruments are used in contact angle measurement, surface free energy analysis, and surface or interfacial tension measurement.The V TECH (VT) series contact angle meters have a range of systems starting from DMs-200, which is the basic model, to the most sophisticated VT-701.The VT-200 model is used to determine contact angle using the sessile drop method in static mode.

From model VT-CE1, all instruments can determine contact angle using the sessile drop method in static mode as well as in dynamic mode. The surface tension of a liquid sample can also be determined. The robust FAMACS software ensures that the system can also give dynamic contact sessile drop method,extension/contraction method, surface or interfacial tension of liquids with pendant drop method,sliding method, and dynamic sliding method. This is the most automatic model and even stage movement and droplet deposition can be controlled through the PC.

 

Optional accessories are numerous to choose from including computer-controlled dispenser, sliding method, temperature control of stage, temperature control of dispenser, and high speed camera.With the surface free energy software, the solid surface free energies and their components from the results of contact angle with different liquids can be measured.If surface free energy is the main analysis, then there is also an option called surface energy kit which consists of five kinds of probe liquids and proper needles.

 

Applications

The contact angle meter has application in the pharma field, where the wettability of powders can be studied. The contact angle measurement gives remarkable data on wettability and thus pharma companies can use this tool in their analytical research and development. It can also be used to analyze the processes of coating, cleaning, and surface finishing in research institutes.

Product Description:

Deciding which fertilizer to use can be overwhelming, but with a bit of knowledge, you can be sure your garden will get the right amount of nutrients it needs. The first question you’ll need to answer is, “What analysis do I need?” The analysis is actually three numbers you see usually at the middle or bottom of fertilizer packages (for example 10-20-10). These numbers represent percentages of the three major nutrients plants need: nitrogen, phosphorus, and potassium (NPK for short). NUNES is a multi-parameter bench meter that measures twelve methods in low, medium and high ranges essential for monitoring greenhouse and hydroponics operations. It’s three channels allow for a wide range of tests. The optical system of NUNES is based on special sub-miniature tungsten lamps and narrow-band interference filters to guarantee both high performance and reliable results. NUNES has powerful interactive user support that assists the user during the analysis process. A full tutorial is available in the Setup Menu, and the Help Menu provides assistance for every step in the measurement process. This meter can be connected to a PC via a USB cable, where the data can be managed with optional HI 92000 Windows® compatible software.
