Thermo Labsystems Multiskan Spectrum Microplate UV/VIS Reader

Thermo Labsystems Multiskan Spectrum Microplate UV/VIS Reader

Cambridge ID #: 17010

Multiskan Spectrum makes getting results easier, replacing separate spectrophotometers and microplate reading instruments by providing both functions in one convenient, compact instrument.  The Multiskan Spectrum is truly two instruments in one, combining both cuvette reading capabilities and advanced microplate reading in one convenient, compact instrument.  You can easily take quick absorbance measurements in a cuvette between the cycles of a microplate enzyme kinetics experiment. 

 

For maximum flexibility, Multiskan Spectrum accepts all microplate for mats from 6- to 384-wells, as well as cuvettes from standard to ultra micro capacities in glass, plastic, or quartz. You can take multiple photometric readings per well on large format plates, or single measure ments requiring just 30 μl in 384-well plates.

 

Scanning range of 200 – 1000 nm.  The built-in monochromator makes it simple to select any wavelength from 200 nm to 1000 nm in 1 nm steps without ever changing a filter. Sample absorbances can be scanned over the whole spectrum either in microplates or cuvettes.

 

Typical applications of the Multiskan Spectrum

  • UV/Visible spectrophotometry
  • Spectrum scan
  • Nucleic acid analysis
    • RNA concentration (A260)
    • ssDNA concentration (A260)

Molecular Devices Spectramax 190 Microplate UV/VIS Reader

Molecular Devices Spectramax 190 Microplate UV/VIS Reader

Cambridge ID #: 24143
  • The patented multichannel optical design of the SpectraMax® 190 Absorbance Microplate Reader mimics a dual beam spectrophotometer, measures each sample in the plate directly, and eliminates measurement error due to variations in light output between optical fibers on other instruments for more reliable data reporting. The eight-channel system delivers both high precision and speed when reading 96-well microplates for endpoint measurements, kinetic assays, and spectral scans.
  • The optical system of the SpectraMax 190 Microplate Reader is built around a monochromator, which allows for selection of up to six wavelengths at a time for absorbance detection in the UV-visible wavelength range (190 nm - 850 nm). Narrow bandwidths deliver increased measurement accuracy and linearity over the widest range of assays, including DNA quantitation in the UV range.
  • Using the patented PathCheck® Pathlength Measurement Technology, the SpectraMax 190 Microplate Reader transforms each well in a microplate to a fixed optical pathlength cuvette. This temperature-independent normalization corrects for varying well volumes and can eliminate standard curves by allowing the calculation of concentrations directly from the absorbance with a known extinction coefficient, as exemplified with nucleic acid and protein quantitation.

    Persee A3G *NEW* Atomic Absorption Spectrophotometer

    Persee A3G *NEW* Atomic Absorption Spectrophotometer

    Cambridge ID #: 21356

    Features:

    The A3 Atomic Absorption Spectrometer is a high performance automated instrument designed to meet the requirements of the modern laboratory. Due to its versatility and performance it can be used for a wide range of applications. 

    Three flame options are available to the user with the Air/Acetylene being the standard configuration. This flame can be used for nearly all standard elements while the N2O/Acetylene and the Air/LPG (natural gas) are available as an option for the more demanding of elements. All three flame configurations offer coded burner for full safety protection. 

    The graphite head is fixed into the optical path to maximize performance and eliminate drift. The temperature of the transversely heated graphite tube is accurately controlled by means of a precision feedback system. Pyrolytically coated platform tubes are supplied as standard to improve the performance and eliminate many analytical problems associated with this technique. 

    The flame and graphite furnace can be changed over by a simple selection in versatile AA Win Pro software.
