Description

Kalstein YR06702 series of UV-Visible Spectrophotometers represents the gold standard in photometric analysis for laboratories demanding absolute precision and versatility. These instruments, ranging from single-beam to advanced dual-beam configurations , operate in a wavelength range of 190–1100 nm, enabling critical measurements in the chemical, pharmaceutical, and biotechnology sectors. Equipped with tungsten (W) and deuterium (D2) light sources, they guarantee superior stability of ≤0.001 A/h, resulting in reproducible results even under intensive workloads.

The technology integrated into these devices stands out for its intuitive user interface, with touch screens of up to 10 inches that facilitate autonomous system control, without strictly depending on an external computer.

Design and Technology: Cutting-Edge Functionality

The YR06702 series design has been optimized to minimize stray light (≤0.05%T) and maximize resolution. While the base model offers a bandwidth of 1.8 nm, the premium YR06702-3 version allows for variable bandwidth (0.5/1/2/4 nm), ideal for research requiring extremely fine peak discrimination. The robust optical system and the option for data output via Bluetooth or USB ensure quick and error-free integration of results into your LIMS.

Frequently Asked Questions (FAQ)

• What is the main difference between the single-beam and dual-beam models? The single-beam (YR06702) is ideal for routine high-speed measurements, while the dual-beam (YR06702-1/3) automatically compensates for light source fluctuations and solvent noise, offering greater stability in complex analyses.
• Does it require external software to operate? No, it has a built-in standalone operating system. However, we offer optional PC software for deeper data analysis and regulatory compliance.

Advantages and Disadvantages

Advantages:

• High Precision: Wavelength accuracy up to ±0.1 nm in higher models.
• Modern Interface: Color touchscreen that eliminates the need for peripherals.

Disadvantages

• Preheating: Requires 2 hours to reach maximum stability of 0.001 A/h.
• Weight and Size: As they are high-precision equipment, they require a fixed and level table space.

Product Use in the Field

In clinical settings , these spectrophotometers are essential for quantifying nucleic acids and proteins. In the environmental industry , they are used to detect contaminants in water using highly linear calibration curves. Thanks to their photometric range of -0.3 to 3 Å, researchers can analyze samples with varying concentrations without excessive dilution, optimizing turnaround time in the laboratory.

Recommendations and Maintenance

To ensure the longevity of your YR06702 Series Spectrophotometer , it is recommended that you:

1. Electrical Stabilization: Use a voltage regulator to protect deuterium and tungsten lamps against power spikes.
2. Optical Cleaning: Clean the cuvettes with spectroscopic grade solvents to avoid interference in the reading of diffuse light.
3. Periodic Calibration: Although the equipment is highly stable, a semi-annual validation of the wavelength accuracy using certified filters is suggested.
