DESCRIPTION

Spectrometer 

Ease of operation is achieved by using a microprocessor to perform most of the repetitive talks usually requiring prolonged operator action. The instrument is capable of performing absorbance, concentration and transmittance measurements on up to five samples plus on reference at wavelengths in the 200 nm to 900 nm range. Ideal for biological samples when using standard 10 mm cuvettes. Pharmacia LKB Biochrom ULTROSPEC II is designed as a simple to use instruments capable of producing rapid measurement of light absorption or transmission. The LKB Biochrom Ultrospec II UV/Vis Spectrophotometer is designed to produce rapid measurements of light absorption or transmission in both the ultra-violet and visible spectra. Capable of performing the absorbance, concentration and transmittance measurements on up to five samples plus one reference, the Ultrospec 4050 features wavelengths ranges from 200nm to 900nm.

Calibration error 3
Hello, after replacement of the tungsten lamp, the calibration fails at step 3. Does anybody know what this means? It would maybe already help if the user manual was available in total, as the section 5 with error messages is missing in the uploaded pdf file. Thanks a lot for your help.Reply

LKB Pharmacia / Biochrom Ultrospec II Spectrophotometer - Problem with Calibration

Hi,

I have a problem with my LKB Pharmacia / Biochrom Ultrospec II (4050) Spectrophotometer. The calibration procedure on power up performs apparently well (no error occurs). But I have a wavelenght-offset of approximately 40nm. A real value of 530nm is displayed as 490nm. If I deactivate the calibration on power up the measured values are close to the real values, but not exactly due the missing calibration.

Is here someone who knows more about this old device and could help me? The manufacturer can't help me, because the support for this product ist not longer available.

Or has someone a service manual or knows somebody who might have one?

Thanks and regards!

Karl
