• Scanning diode array technology • Compact and lightweight with a small footprint • USB ports for data storage and printer connectivity • Ideal for applications in education and routine testing in clinical,

The SP-400 series spectrophotometers are the first scanning spectrophotometers in our range to leverage diode array technology to produce exceptionally fast results. The range includes two models. Model SP-400-VIS covers a wavelength range of 335 to 800 nm with a spectral bandwidth of 7 nm. Model SP-400-UV covers a wavelength range of 198 to 800 nm with a spectral bandwidth of 5 nm. The SP-400 series spectrophotometers are covered by a 3 year warranty. Multiple measurement modes available Key Features • Scanning diode array technology • Color touchscreen navigation • Small footprint and...

SP-400 Series Spectrophotometers Measurement Modes (continued) Both models perform an exceptionally fast spectrum scan across the entire wavelength range in less than 6 seconds; displaying the results at 1 nm resolution across the selected range. The kinetics measurement mode can be used to measure the change in absorbance over time for up to 3 wavelengths simultaneously. The concentration can also be calculated following completion of the kinetics experiment. Diode Array Technology The benefits of diode array technology include very fast scanning with the ability to scan the entire...

SP-400 Series Spectrophotometers USB Connectivity There are two USB ports for data storage and printer connectivity. The easy-access USB port on the front of the instrument can be used to easily store results and transfer data as tab delimited text files to Microsoft® Excel®. As well as results storage, quantitation curves can also be saved to a USB memory stick for easy and quick access, so there is no need to recreate the calibration curve each time you need to perform a measurement. User selected spectral analysis points (up to 50) can also be saved to USB memory stick or printed. The...

SP-400 Series Spectrophotometers Accessories The SP-400 series spectrophotometers have been designed to be compatible with an extensive range of accessories. Accessories include a test tube holder, rectangular longpath cell holder (10 to 100 mm), micro-cuvette holder, heated cuvette holder, and a printer. All of the accessories are easy to interchange using the ergonomic thumb screw. Test Tube Holder For applications where the temperature of the sample needs to be controlled, there is a heated cuvette accessory. The heated cuvette holder accepts a 10 x 10 mm cuvette and enables 2.5 mL of...

SP-400 Series Spectrophotometers Accessories (continued) Heated Cuvette Holder For applications where the temperature of the sample needs to be controlled, we offer a heated cuvette accessory. The heated cuvette holder accepts 10 x 10 mm cuvettes and can be easily fitted and removed without the need for any tools. This accessory has a temperature range of 32 ºC to 42 ºC. The heated cell accessory is supplied with a US, UK and EU power lead which is required to power the spectrophotometer and the heated cuvette holder. Printer The printer connects to the spectrophotometer via the USB port on...
