Dipping Probes World’s Smallest fiber Optic Dipping Probe for UV/Vis Spectroscopy 10 mm light pathlength DipTip™ is a miniature transmission probe for microliter spectroscopic sampling. DipTip’s tip diameter is only 1.5 mm—the size of a 17-gauge needle. It will fit into all micro centrifuge tubes on the market and is a useful tool for measuring protein and DNA samples. It can also be used for a dissolution system. Because of WPI’s proprietary optical design, the standard DipTip is not only four to five times smaller in diameter than any other product on the market, but also costs 50% less. Now, the new Mini DipTip (with smaller handle and shorter shaft) is ten times more efficient than the standard DipTip. 5 mm light pathlength 2 mm light pathlength New Mini DipTip features smaller handle, shorter cable, greater efficiency! Microliter samples can be analyzed cost effectively when you combine the Mini DipTip with one of the following: ● The Fiber optic-based spectrometer (Tidas I) and a light source (D4H and FO-6000) ● A spectrophotometer (Tidas 100) ● WPI’s biophotometric detection system (LEDspec) The Mini DipTip is ideal for multi-channel applications. ● ● ● 10 times more efficient than standard DipTips Compatible with many standard spectrophotometers (600µm fiber optic coupler connections) More flexible cable than standard DipTips SPECTROSCOPY DiPtiP SPECifiCAtiOnS DIP-NIR TIP DIAMETER LIGHT PATHLENGTH WAVELENGTH RANGE (nm) SAMPLE VOLUME REQUIRED DISTANCE FROM TIP TO UPPER EDGE OF SAMPLE WINDOW FIBER LENGTH FIBER OPTIC CONNECTION LAUNCH FIBERS (2) NA = 0.22 RETURN FIBER (1) NA = 0.22 LAUNCH FIBER BUNDLE (7 x 200μm) RETURN FIBER BUNDLE (7 x 200μm) 1.5 mm 2, 5, 10mm 350-1000 20-50 μL 7 mm 1.5 m SMA 905 400 μm 400 μm DIP-UV-SR 1.5 mm 2, 5, 10mm 200-1000 20-50 μL 7 mm 1.5 m SMA 905 400 μm 400 μm 680 μm* 680 μm* DIP-UV-MINI 1.5 mm 2, 5, 10mm 200-1000 20-50 μL 7 mm 1.0 m SMA 905 *Circular packaging of the fiber bundle results in an active area equivalent to a fiber with a core diameter of 680 µm. Using a 600 µm connection is recommended and will result in negligible light loss. DNA samples (with a sample volume of 50µL inside micro centrifuge PCR vials) were measured in PBS with concentrations 0–43µg/mL using a Tidas spectrophotometer.
