SPT-2
  • Sample volumes as small as 2 microliters
  • Ideally suited for protein and DNA analysis
  • Optimal UV Efficiency

Features

With its especially low sample volume of only 2 microliters, the SpectroPipetter is ideally suited for protein and DNA analysis. In its outward design, the SpectroPipetter resembles a standard laboratory pipette. Fluid is taken up and expelled by means of a manual plunger, just as in a standard pipette. The plunger is made of an optical fiber bundle, protected by stainless steel tubing. In addition to moving the sample in and out of the sample chamber, it delivers and collects the light used for absorbance measurements. This design allows easy, quick and accurate spectroscopic measurements of small sample volumes. Two fiber optic cables are used to connect the SpectroPipetter to a spectrophotometer. The launch cable is used to couple light from a light source to the sample chamber, which is designed using waveguide principles. The return guides the light from the sample chamber to a spectrophotometer. Further, modular sample systems can be assembled using WPI’s PDA (TIDAS I) or CCD based spectrometer modules and WPI’s range of UV/VIS light sources (D2H, and FO-6000). We recommend the SPT-2 for TIDAS I-based systems.

DNA/RNA Quantification Application Notes using:
 • 2mm cuvette
 • DipTipMini

Optional Cleaning Kit

In addition to the standard accessories, the optional Ultrasonic Cleaning Kit is highly recommended for keeping the sample chamber clean and for removing any residual sample fluid or dye from the sample cell. The kit contains an ultrasonic cleaning bath for the tip module, a special stand for placing the SpectroPipetter in the ultrasonic bath and a bottle of concentrated cleaning solution. A built-in timer provides a 20-second cleaning cycle with a high intensity ultrasonic wave each time it is activated.
