About This Product
■Product overview
DS5 is a dual beam UV-visible spectrophotometer that can be operated intuitively with a touch panel. It is compatible with measurements from 190 to 1,100 nm, and uses a dual beam method to obtain highly accurate and stable measurement values (displayed as absorbance or transmittance) even over long periods of measurement.
Bandwidth can be selected from 5 steps from 0.5 to 4.0 nm, and scan speed can be selected from 9 steps from high resolution 10 nm/min to a maximum of 6,000 nm/min, allowing measurement under appropriate conditions for each measurement target. is. We also have a wide selection of accessories for temperature control, flow measurement, glass, and film measurement. Control via PC is also possible as an option.
■Dual beam method
Since the sample and reference are measured at the same time, blank correction can be performed automatically. Since it is less susceptible to changes in the light source and detector over time, highly accurate and stable measurement values can be obtained even over long periods of time.
■Intuitive operation
Equipped with a 7-inch color touch panel, intuitive and easy-to-use software menu
■Optimization of measurement conditions
Bandwidth can be selected from 5 levels: 0.5, 1.0, 1.5, 2.0, and 4.0 nm. You can choose from nine scan speeds: 10, 100, 200, 400, 800, 1,200, 2,400, 3,600, and 6,000 nm/min.
Rich software features
■Photometry & quantitative mode
Absorbance/transmittance measurement at one wavelength or multiple wavelengths (up to 5 wavelengths), quantitative analysis, nucleic acid/protein A260/A280 ratio, concentration measurement, calibration curve creation
■Kinetic mode
Time course measurement from 10 seconds to 27 hours
■Wavelength scan
Full spectrum scan from 190nm to 1,100nm, 9-step scan speed selection from high resolution 10nm/min up to 6,000nm/min
■Data analysis
Scale change, tracing, spectrum overwriting, peak/valley detection, smoothing, differentiation, area/rate calculation, etc.
■Performance check function that increases data reliability
At startup, it automatically performs self-diagnosis and wavelength calibration of various parameters (wavelength accuracy, wavelength reproducibility, bandwidth, baseline flatness, baseline stability, noise level, etc.).
*Equipped with GLP/GMP function
■A wide variety of accessories
We have a wide selection of accessories for temperature control, flow measurement, glass, and film measurement.
