SPT-2 SpectroPipetter-II Dipping Probe 光譜移液器
Item#: 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.
