FTIR is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas. An FTIR spectrometer simultaneously collects high spectral resolution data over a wide spectral range.

The Brookfield Viscometer measures fluid viscosity at given shear rates. Viscosity is a measure of a Fluid’s resistance to flow.

(UV–Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visiblespectral region. This means it uses light in the visible and adjacent ranges. The absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved. In this region of the electromagnetic spectrum, atoms and moleculesundergo electronic transitions. Absorption spectroscopy is complementary to fluorescence spectroscopy, in that fluorescencedeals with transitions from the excited state to the ground state, while absorption measures transitions from the ground state to the excited state.

Tablets are being formed by compressing the granules using the compression machines. It is possible to produce more than 500000 tablets per hour. A formulation takes place by the combined pressing action OF TWO PUNCHES AND A DIE.

Tablets Dissolution is a standardized method for measuring the rate of drug release from a dosage form. The principle function of the dissolution based on optimization of therapeutic effectiveness during product development and stability assessment.
