What types of applications is the Labtron Visible Spectrophotometer LVS-A20 suitable for?

Labtron Visible Spectrophotometer is ideal for precision measurements in fields such as organic and biochemistry, medical diagnostics, food safety, and environmental monitoring. It offers a wavelength range of 340 to 1000 nm, making it suitable for analyzing compounds that absorb in the visible spectrum. Researchers and technicians use it for qualitative and quantitative analysis of solutions. The device supports both routine testing and more advanced analytical procedures.

How does the holographic blazed grating of the Visible Spectrophotometer enhance performance?

The Visible Spectrophotometer's holographic blazed grating improves wavelength accuracy and reduces stray light, resulting in more precise and reliable readings. It ensures better monochromaticity, which is essential for accurate photometric measurements. This technology enhances the instrument's performance when analyzing complex samples with overlapping spectra. As a result, users can trust the integrity of their data.

Can the Visible Spectrophotometer accommodate different cuvette sizes for various sample volumes?

Yes, our Visible Spectrophotometer's sample compartment is compatible with cuvettes ranging from 5 mm to 50 mm in size. This flexibility allows users to work with both small and large sample volumes, depending on the experimental needs. It also makes the instrument adaptable for both low- and high-concentration solutions. The adjustable compartment ensures proper alignment for optimal light transmission.

What features contribute to the safety and longevity of the Visible Spectrophotometer?

Labtron's Visible Spectrophotometer uses automatic light gate technology to protect the photoelectric sensor from excessive light exposure, reducing wear and extending sensor life. This feature eliminates the need for a blackbody to block light during idle periods. Additionally, the device is built with durable components and operates at a low power consumption of 80 W. These elements collectively support safe and long-term operation.

How does the Visible Spectrophotometer ensure consistent and repeatable measurement results?

The Visible Spectrophotometer offers high photometric repeatability of less than or equal to 0.2 %T and wavelength repeatability of less than or equal to 1 nm, ensuring stable results across repeated tests. Its microprocessor control maintains consistent performance and automatically adjusts for zero and full-scale calibration. These features help maintain measurement integrity, especially during long testing sessions or when comparing multiple samples. It is ideal for environments that require dependable reproducibility.
