The Beckman DU 650i Spectrophotometer is a full-featured scanning spectrophotometer with micro-focused beam technology provides precise and accurate results for samples as small as 5uL. The micro-focused beam delivers the full energy of the beam to the microsample, unlike standard beams, which can lose as much as 80% of their energy when applied to a microvolume sample.

Features:

  • Scans or fixed wavelength reads
  • Absorbance and transmittance readings
  • Port for dot matrix printer
  • RS232 port which can be configured for an XY plotter
