micro-volume accessory and universal power supply.
Designed with your convenience in mind, the 74 series of spectrophotometers provides accurate and reliable results in various applications from teaching, to industrial applications, to routine sample analysis in quality control environments. Navigation is fast and intuitive on the large 7” high-definition color touchscreen display. View scans and curves, zoom in and out, and select points right on the screen even when wearing gloves. The home screen provides easy access to measurement modes as well as saved results and methods.
Programmed measurement modes include photometric for single wavelength measurement, concentration for measuring concentration using a standard or factor, spectrum for a high purity scan across the entire wavelength range, quantitation with the ability to create a calibration curve using up to 20 standards, kinetics to monitor change over time, as well as multi-wavelength mode.
Manage data with the Ethernet connection or multiple USB ports readily located on the front of the unit. Save methods and results in the generous 3.6 GB of internal memory for quick recall.
Large sample chamber lid provides easy access to loading and unloading samples and a variety of accessories. The domed design accommodates tall multi-cell changers or test tubes while still maintaining a light-tight sample chamber. Models 83056-21, -22, -31 and -32 are fitted with a 10 mm x 10 mm cuvette holder to accept a sample volume of 3 mL. Nano spectrophotometers 83056-23 and -33 are fitted with a micro-volume accessory enabling sample volumes as low as 0.5 µL to be pipetted directly onto the read head, removing the need for cuvettes and conserving valuable samples. It’s the perfect analysis tool to measure the purity and concentration of biological samples.
