PS-2600A wireless spectrometer
The PS-2600A wireless spectrometer is designed for introductory chemistry, biology, and physics experiments. Free PASCO spectroscopy software lets students quickly obtain absorbance spectra in the visible range. After specifying a target wavelength, they can select displays comparing absorbance with concentration (Beer's law), tracking reaction rates (kinetics), or investigating emission spectra with an optional fiber-optic cable. Bluetooth Low Energy (BLE) or USB connects easily to student devices including Mac®/Windows® computers, Chromebook™ notebooks, iPad® tablets, and Android™ tablets. Included free PASCO spectroscopy software simplifies operation. Fast scans range from milliseconds to minutes depending on experimental settings. Light from an LED-enhanced tungsten lamp passes through the solution, enters a slit, and reaches a high-quality diffraction grating. Separated colors fall on the sensor, and the slit image illuminates more than 1000 sensors in the array on the opposite side. The charge-coupled-device (CCD) array detects each color's brightness for analysis at specific wavelengths. With an optional fiber-optic cable, the instrument analyzes light from emission-spectrum experiments: Insert the cable into the cuvette holder and aim its end at the source to collect data. Solvents used must be compatible with polystyrene cuvettes and the ABS-polymer housing. Solutions containing strong organic solvents such as acetone require glass cuvettes or 12-millimeter (mm) test tubes. Leaks of these solvents damage plastic cuvettes and the instrument's internal structure. The PASCO wireless spectrometer integrates fully with our easy-to-use spectroscopy software. This free software supports most student devices for quick sharing and viewing of data within experimental groups.
