Detail SPECTROPHOTMETER Type T70-T70+
Features
· Accurate Analysis: Holographic grating greatly reduces stray light of the instrument and makes the analysis more
accurate
· Stable Performances: The split beam ratio optics ensures good stability
· High-Speed Measurement: The fastest scanning speed is over 1000nm
· Powerful Functions: The main unit of the spectrophotometer can perform photometric measurement, quantitative
measurement, spectrum scan, DNA/ Protein analysis and can print data. When connected to a computer the Spec
UV software adds many additional functions, such as 3D spectrum analysis, GLP laboratory protocol, etc.
· Convenient Operation: High degree of automation, the operator only needs to press keys twice when measuring
ordinary samples
· Easily Upgraded: Many optional accessories enhance the flexibility and the measurement range of the instrument
· Easy Routine Maintenance: The simple mechanical structure and modular electrical design make the routine
maintenance easy
· Original Technology: The deuterium and tungsten lamps can be easily replaced and are supplied pre-aligned. A
motorized automatic 8-cell holder is supplied as a standard, which is particularly useful for the determination of
pesticides
