Camspec M501 UV-Vis Spectrophotometer

The M501 is a single-beam scanning UV-Visible spectrophotometer with an on-board LED display and keypad offering local control. This instrument can be linked and controlled by a PC via UV Analyst software.

The sealed and solvent-resistant tactile keypad has an alpha-numeric entry for user file names and user entry of units making it a practical and methodical instrument.  The M501 also has a real-time clock for date and time stamping of results to help with organisation and clarity of analysis. There is also the option of monitoring the usage status of the lamps for maximum longevity and optimum performance.



  • Local Control Software - All methods are included
  • Basic Mode - Measures Absorbance, %T and Concentration.
  • Quantitative – Up to 10 standard solutions maybe used for a calibration
  • Wavelength Scanning
  • Kinetics - For time course scanning or reaction rates
  • DNA/Protein – Concentration & DNA Purity are calculated
  • Multi-wavelength - up to 10 wavelengths
  • Performance Validation - for the GLP compliant laboratory

User Interface                                                                                         

The user interface of the M501 Single Beam Spectrophotometer  includes Basic Mode (Abs, %T, Conc), Quantitative (concentration calibration curves), Wavelength Scanning, Kinetics (including timedrive), DNA/Protein, Multi-wavelength and Performance Validation. In Basic Mode, the result is continuously displayed (no need to “press to read”)   


PC Control                                                                                                      
TheM501 has a 2 x USB2 outputs. One for the download of data to a USB Memory stick to be analysed offline and one for the control of the spectrophotometer when the UV/VIS Analyst software is purchased. Comprehensive Camspec Application Software is available, together with small PC programs, dedicated to specialist tasks.
