Specifications

At the heart of Probe Drum is the sample holder, fitted with stirring, temperature control, accessibility for an electrode and an automated titration system. Sample parameters are set through user-friendly experiment-oriented software, and integrated with the optical measurement parameters.

  • Sample: a standard optical cuvette, base 12.5*12.5 mm, internal volume 1 ml or 3 ml with Z = 8 mm.
  • Titration volume resolution: 20 nl minimum addition.
  • Titration time resolution: ~1s (assuming a single-shot spectrum at every titration point)
  • Temperature control: a Peltier element, range 12-70°C with 0.1°C precision (optional range 2-90°C).
  • Electrode duct: 3.4 mm diameter.

The optical lines monitoring the sample comprises a CCD-based detector and a total of 16 different light sources in two spacial orientations. This gives the following approximate optical specifications:

  • Fluorescence excitation from 260 to 650 nm
  • Absorbance measurements over the whole detection range.
  • Laser based static light.scattering (650 or 635 nm laser)
  • Spectral detection range: 220-790 nm (optional range 200-1200 nm)
  • Spectral resolution: up to 1.2 nm
  • Time resolution: 10 ms (assuming single-shot spectra)
