Spectrophotometers

Spectrophotometer Cells / Cuvettes

Scientific Instruments has a large range of Spectrophotometer cells available.

The most common type used is the Type 1 G 10 this is the standard type cell in glass.

Material Code Wavelength Usual spectral range of application
Optical Glass G 334 to 2300nm Visible light
Infrasil Quartz I 220 to 3800nm Near Infrared
Spectrosil Quartz Q 170to 2600nm UV region

If you are measuring below 350nm then a Quartz cell is required for the light to

transmit through the specimen. I.e. Type 1 Q 10.

Matched sets of cells can be ordered normally 2 or 4.

We can also supply Demountable Cells & Micro Flow Cells for your specific type of work.

U-5100

Hitachi High-Technologies Corporation (TOKYO:8036, Hitachi High-Tech) today announced the development of the Ratio Beam Spectrophotometer U-5100, a user-friendly system that offers a small footprint, energy savings, and excellent design qualities. Sales of the U-5100 to universities, research institutions and other customers around the world are started in April , 2010.

A spectrophotometer is a device for measuring the density of substances in a test sample by directing a beam of white light split into individual colors using a prism or diffraction grating at a sample and detecting the wavelengths of light that pass through. With a wide range of applications in academic and industrial fields such as materials science, environment, pharmaceuticals, and biotechnology, spectrometers have already proven useful in research and development.

U-2810

The U-2810 is the newest generation of Hitachi’s low cost UV-Vis spectrophotometers. Over a span of forty years, this UV-Vis spectrometer family has evolved to the premier U-2810. This instrument can be used for most research, routine, and teaching laboratory applications around the globe. This highly dependable instrument, designed with the latest in technology, meets the demanding specifications needed for today’s analyses. It’s small footprint design ensures maximum usage of bench space and is fully compliant with Pharmacopeia requirements.


Features

  • Simple and dependable
    Features, such as auto source change, provides the correct source lamp at the proper time when moving from one range to another and can be selectable by the user. The only moving part in the system is the grating keeping the system low in redundancy. Using less mechanical parts makes this system highly dependable.
  • High energy optical system
    Designed using the high resolution Seya-Namioka monochromator, a concave grating which eliminates chromatic aberrations. This design eliminates two additional optical surfaces and the associated energy loss due to these optics, thus providing the user with a simpler yet energy efficient system. Less optics provides the user with two large benefits, higher signal to the detector providing very low noise levels and a very dependable yet simple designed system.
