DU 800 Series

The DU 800 Spectrophotometer is a PC controlled system intended for use in quantitative and qualitative analysis in biological and industrial procedures that require spectrophotometric measurements in the UV and visible region of the electromagnetic spectrum. If the instrument is used in a manner other than as described, the safety and performance of the instrument can be impaired.

The DU 800 Spectrophotometer operates in the wavelength range of 190 to 1100 nm and has a bandwidth of <= 1.8 nm. The focused micro-beam design provides a wide linear range and other specific benefits for small volumes and precious samples. Various accessories are available to address micro-volume samples and individual application requirements.

Beckman Coulter DU 800 not communicating via USB to PC

I have a BC DU 800 that will not communicate with the PC. I have uninstalled and reinstalled the software on the PC like a new installation. The USB port sees the device, the software is seeing the device, but they will not talk. Any suggestions?

Wavelength calibration failed

  I perform the wavelength calibration as the page # 107 manual says (both lams on , both lamps are brand new). It gives me an error message as bellow: "Wavelength calibration failed " I am wondering if anyone can help...

Godrule

My Spectrophotometer Is on and all UV AND VISIBLE light is on. Whe performing Perfomance validation its fails on Wavelength Acuracy, Resolution AND Baseline Flatness. Please asist.
