Description
Overview
GAOTek dual-wavelength UV-Vis’s spectrophotometer is an automatic type, high precision instrument, the wavelength is adjusted by Shogun screw structure, the instrument is widely used in education, medicine, electricity, chemistry and chemical engineering and other fields. Its integrated design assures long-term stability and durability. The highly stable optics and two detectors measure the sample and reference simultaneously optimizing measurement accuracy. It has measurement modes for photometrics, concentration, multi-wavelength, spectrum scanning, kinetics, quantitation, DNA and protein analysis.
Features
- Automatic transfer 0, transfer 100% functional
- Universal parallel interface, you can print the title bar, the measured data, curve parameters, curve standard sample points and curves With USB Interface
- Large sample pool (5 mm to 100 mm)
- The large LCD monitor can display multiple sets of data
- Master Standards can be directly input, and the corresponding concentration values establish a standard curve for quantitative measurement by direct input K, B factor to establish a standard curve for quantitative measurement
- Spectrum scanning can be achieved through the PC software control is more precise and flexible measurement requirements (optional) Standard curve parameters can be powered down to save the measurement setup with up to 10 standard sample for measurement function of standard curve establish
- Huge memory space to store multiple sets of data and curves
- light automatic switching, automatic switching filter
- Single-chip microcomputer control, 128 x 64 LCD
- Automatic wavelength adjustment
