Creatinine Measurement

The UV-Vis Spectrophotometer (SP-UV1100) is a high-performance, single-beam benchtop instrument engineered for accurate, reproducible analysis of nucleic acids, proteins, clinical chemistry analytes, and pharmaceutical compounds in clinical diagnostics, molecular biology, pharmaceutical quality control, and research laboratories. Covering a wavelength range of 200–1000 nm with automatic switching between tungsten and deuterium lamps, this spectrophotometer provides the analytical versatility required for routine and specialized laboratory workflows, including nucleic acid purity assessment, enzyme kinetics, and quantitative clinical chemistry.

Every UV-Vis Spectrophotometer (SP-UV1100) is individually factory calibrated and supplied with a calibration certificate traceable to national standards, delivering exceptional photometric accuracy of ±0.003 A at 0.5 A and photometric repeatability of ≤0.0015 A at 0.5 A. The instrument's baseline stability of ≤0.002 A/h at 500 nm after a 2-hour warm-up ensures reliable, drift-free measurements for endpoint and kinetic assays. A large 128 × 64 dot backlit LCD display with adjustable brightness provides clear data visualization, and the 4-position sample compartment accommodates standard 10 mm path length cuvettes, with optional holders available for path lengths from 5 to 100 mm.

Key user-focused features include automatic wavelength calibration via arrow keys to minimize user errors, large-capacity data storage for up to 200 test data groups and 200 standard curves with automatic backup to prevent data loss during power interruption, and multi-function measurement modes including photometric (fixed wavelength), quantitative analysis (standard curve), and multi-wavelength scanning (up to 10 wavelengths). The optional Wave Professional PC software enables advanced functions including spectrum scanning, time-scan kinetics (up to 12 hours), and specialized nucleic acid/protein measurement functions for molecular biology applications.

The UV-Vis Spectrophotometer (SP-UV1100) is supplied with four glass and two quartz square cuvettes (3.5 mL, 10 mm path length) and includes USB and parallel ports for printer connection and data export. The instrument is manufactured under ISO 9001:2015 and ISO 13485:2016 quality management systems, and the manufacturer's CNAS-certified calibration laboratory ensures measurement traceability and confidence in results.

For the clinical laboratory scientist, molecular biologist, and pharmaceutical quality control analyst, the UV-Vis Spectrophotometer (SP-UV1100) delivers the accuracy, stability, and versatility required for DNA/RNA purity assessment (260/280 and 260/230 ratios), protein quantification (A280, Bradford, BCA, Lowry), enzyme kinetic assays (ALT, AST, ALP, GGT, LDH, CK), and routine clinical chemistry testing (glucose, cholesterol, triglycerides, bilirubin, creatinine, uric acid). For the patient, reliable, traceable spectrophotometric analysis ensures that diagnostic results are accurate and reproducible, directly supporting effective clinical decision-making, appropriate treatment selection, and confident disease monitoring.
