Double-Beam UV-Vis Spectrophotometer JK S-2600S

The 2600 series spectrophotometers boast advanced functions such as quantitative measurement, wavelength scanning, time scanning, multi-wavelength testing, and DNA/protein testing. Characterized by high precision, high resolution, low noise, and low stray light, they are particularly suitable for fields like scientific research, medical inspection, life sciences, environmental monitoring, metallurgy, and chemical engineering.

Instrument Functions

• Photometric measurement: Transmittance (T%), absorbance (Abs), and energy (E).

• Quantitative testing: Concentration (C) via coefficient method or standard curve method.

• Wavelength scanning (spectral scanning): Scanning range, interval, and speed can be set.

• Time scanning (kinetics): Measures change patterns and calculates reaction rates.

• DNA/protein determination: Direct display of ratios and concentrations; methods can be customized.

• Multi-wavelength testing: Simultaneously measures results at multiple arbitrary wavelengths.

• Other functions: System applications, spectrum/data processing, report printing, etc.

Instrument Features

• Dual-beam optical path: Low drift and high stability; compensates for reference changes, suitable for long-term testing.

• Sliding sample cover design: Can be opened/closed even when holding items with both hands, easy to operate.

• Spacious sample chamber: Accommodates 5–100mm cuvettes and supports accessories for various tests.

• High-quality optical and electronic components: Ensure high precision and low stray light.

• Large dot-matrix LCD: Clear display of spectra and data; user-friendly interface, simple operation.

• Narrower spectral bandwidth, higher resolution: Fully meets pharmacopoeia requirements, wider application range.

• Long-life, eco-friendly flange-mounted deuterium lamp: No optical adjustment needed when replacing the lamp.

• Real-time saving of spectra and data: Retains data even after power outage; printable and exportable to PC.

• Sturdy base and optical bracket: Imported key components, durable for long use.

• Standard PC scanning software: Easier online operation; expands data processing and storage capabilities.
