Specifications include, but are not limited to: Circular Dichroism Spectrometer; 1.
At least 180-400 nm, preferably larger. Must be accurate to 0.2 nm in this range.
Measurement of UV/Vis absorbance and CD, simultaneously if possible
Measure individual or multiple wavelengths during a temp ramp
Must be able to measure at least between -20 and 110 °C, accurate to 0.1 °C.
<0.01 mdeg in 180-400 nm range.
Ability to hold 5-6 cuvettes with 1 mm pathlength.
Ability to measure volumes <5 μL.
Ability to limit sample exposure to light during runs to prevent degradation by light.
Should include all cuvettes to run 5-6 samples at once.
Software to run instrument must be included and would ideally automatically calculate Tm values.
Vendor should have service technicians available, preferably nearby for quick access in the event of an urgent maintenance or repair need.
