Double Beam UV Visible Spectrophotometer available as either a standalone instrument of a PC-control

Double Beam Spectrophotometer - (UV 3200)

The two detectors measure sample and reference respectively and simultaneously for optimizing measurement accuracy. They provide excellent performance for measurements in the range of 190 to 1100nm. They are suitable for pharmaceutical, biochemical and clinical lab applications as well as routine applications such as quantitative analysis, kinetics, wavelength scan, multiple components  and DNA/protein.

1. What does a UV spectrophotometer measure?

UV-Vis Spectroscopy (or Spectrophotometry) is a quantitative technique used to measure how much a chemical substance absorbs light. This is done by measuring the intensity of light that passes through optical components with respect to the intensity of light through a reference sample or blank.

2. What are the main components of a UV VIS spectrophotometer?

There are four basic components to a simple single beam UV/Vis spectrophotometer; a light source, a monochromator, a sample, and a detector.

3. What is the difference between UV and visible spectrophotometry?

Molecules having non-bonding electrons can absorb the energy in the form of UV or visible light to excite these electrons to higher molecular orbitals. ... Ultraviolet-Visible Spectroscopy is absorption spectroscopy in the UV and visible portion of the electromagnetic spectrum.

4. Is infrared radiation dangerous?

In general, no -- at least from naturally occurring physical processes. Any form of radiation -- including visible light or radio waves -- could potentially be dangerous if highly concentrated into a narrow beam (that is the principle of lasers) of very high power.

5. What is the function of UV spectrophotometer?

UV / Vis spectrophotometer measures the absorbance of a light when it passes through a sample. The light absorbed is proportional to the quantity of a chemical in the sample.
