The WPI's SpectroPipetter-II immersion probe with a sample volume of 2 ?µl can be used for spectroscopic measurements of small amounts of protein and DNA in field experiments.
The SpectroPipetter is perfect for protein and DNA analysis because to its exceptionally small sample capacity of only 2 microliters. The SpectroPipetter looks like a typical lab pipette from the outside. Similar to a normal pipette, fluid is injected into and ejected using a manual plunger. An optical fiber bundle that is shielded by stainless steel tubing makes up the plunger. It delivers and gathers the light needed for absorbance measurements in addition to transporting the sample in and out of the sample chamber. Little sample quantities may be measured spectroscopically with ease, quickly, and accurately because to its design. The SpectroPipetter is connected to a spectrophotometer via two fiber optic cables. The sample chamber is constructed utilizing waveguide principles, and the launch cable is utilized to link light from a light source to the chamber. The sample chamber's return directs light toward a spectrophotometer. Moreover, modular sample systems can be created by combining WPI's UV/VIS light sources (D2H, and FO-6000) and PDA (TIDAS I) or CCD-based spectrometer modules. For systems based on TIDAS I, we advise the SPT-2.
For maintaining the sample chamber's cleanliness and eliminating any leftover sample fluid or dye from the sample cell, the optional Ultrasonic Cleaning Kit is strongly advised in addition to the basic accessories. The kit includes a concentrated cleaning solution, a customized stand for placing the SpectroPipetter in the ultrasonic bath, and an ultrasonic cleaning bath for the tip module. Every time it is activated, a built-in timer offers a 20-second cleaning cycle with a powerful ultrasonic pulse.
