PRACTICAL USE & CHECKLISTS
Daily workflow checklist (fast)
Warm up the system per your lab SOP, select the method (photometric / quantitative / kinetics / scan), then perform automatic blank measurement and auto-zero before reading samples. Use the touch screen to review curves and parameters quickly.
Store results internally or on USB/SD, then export via USB for Excel reporting. For quantitative methods, build a calibration curve and enable automatic concentration determination.
COLO.Science & equipment
COLO.Science helps labs select the right UV/Vis configuration (holders, thermostating, sipper systems, software compliance) and implement reporting-ready workflows with stable, repeatable measurements.
If you need an 8-cell holder, Peltier, sipper, or reflectance accessories, we propose a matching configuration based on your applications.
