IIS270-30A

Double Beam Infrared Spectrophotometer

IIS270-30A can be used to record the IR absorption and reflectance spectra of substances in the spectral range of 4000 ~ 400 cm-1. Infrared analysis can be both qualitative and quantitative.  It is a powerful tool to analyze sample structures in the fields such as petroleum, chemical engineering, pharmacy, public health and environmental protection.

FEATURES

ACCESSORIES

For solid powder (qualitative)Tablet machineManual hydraulic pressure, 0-15 t, no oil leakage, no pressure loss.
Advantages: patented product, the base is stable and there will be no rollover during the pressing process.
Tablet moldDiameter 13mm, no need to remove film, can press potassium bromide, medicine and other powders

Advantages: Made of high-strength stainless steel, and the indenter part has undergone "quenching technology", not easy to break.

KBr Spectrum pureThe raw material of potassium bromide single crystal grown by "Czochralski method" has pure spectrum and no miscellaneous peak interference, and can be used to grind solid samples. NaCl and KCl spectrum pure are optional.
Agate mortarDiameter 70mm, mainly to grind solid samples or make solid samples mix evenly.
Advantages: natural first-grade agate, wear-resistant, corrosion-resistant; diameter 70mm, not easy to spill in the grinding process
Liquid (qualitative)Detachable liquid cellKBr windows are usually used for qualitative or quantitative analysis of liquids. ZnSe, NaCl, CaF2 and other materials  can be selected.
Liquid (quantitative)Fixed liquid cell
