Item: Spectrophotometer double beam uv visible spectrophotometer U8 series
Model: ST-U8
High quality flashing xenon lamp is from Hamamatsu, which can start to test directly without preheating. The lamp can be used at least 3-year.
Powerful functions like photometric measurement, quantitative measurement, kinetics, spectrum scan, DNA/Protein test, multi-wavelength test, etc.
In-house massive memory is capable of saving up to 1024M for test data & working curves.
Supports USB storage. The USB port can be used for data transfer, which is easily exported to excel for further processing, analysis and storage.
Large sample chamber can accommodate 5-100mm cuvettes of all kinds.
Extensive accessories are optional, such as auto 8-cell holder, film holder, peltier /sipper system,21 CFR compliant software, built-in printer, etc.
