Here is a selection of parts for a Thermo Evolution Spectrophotometer models 300/600. There is a CVC (Calibration Validation carousel) in a box with a rubber dust blower and a 4GB memory stick which I suspect has the calibration info on it. This is also suitable for the Helios range. The calibration date is 19/01/2012 but since it hasn't been used then I suspect this calibration is still good. The Smart Thermostatted rotary 7 cell changer comes with it as does a manual cell holder for the long pathlength rectangular cells. All these items are new and unused. There is also a CD containing the user and operating manual for this spectrophotometer and the others in the range. The total value of these parts is a few thousand pounds so here is a great bargain if you use or maintain these spectrophotometers.
