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.

F-2500 Fluorescence

Excitation and fluorescence wavelengths of an unknown sample are automatically selected and set. High sensitivity measurement by the S/N ratio of 450 or more with the Raman spectrum of water and measurement of the concentration in a range of 6 orders of magnitude without adjusting the sensitivity are possible. A multistage slit (2.5-20nm) allows to cover a wide range of samples. Various accessories including intracellular Ca measurement are lined up.


Features

  • High sensitivity measurement
    A highly efficient diffraction grating and a low noise detector system have achieved high sensitivity measurement of the Raman spectrum of water with the S/N ratio of 450 or more (band pass of 10nm, response of 2 seconds). Since measurement and result can be displayed by one-touch operation, confirmation is easy.
  • Measures the concentration in a range of about 6 orders of magnitude without adjusting the sensitivity.
    Display range is 0.001-9999. Cumbersome sensitivity adjustment is automatically conducted by the computer. A calibration curve can be created in a concentration range of about 6 orders of magnitude. Quantitative measurement of a sample with unknown concentration can be conducted especially easily.
