In today’s modern laboratories, accuracy, stability, and ease of operation are essential for reliable analytical results. The Double Beam UV-VIS Spectrophotometer Model No. LI-2707, developed by Lasany International, is designed to meet these exact needs. With advanced optics, a large touch-screen interface, and high photometric precision, LI-2707 is an ideal solution for research, pharmaceutical, chemical, environmental, and quality control laboratories.

What is a Double Beam UV-VIS Spectrophotometer?

A double beam spectrophotometer simultaneously measures the sample and reference, eliminating fluctuations caused by light source instability. This ensures higher accuracy, better baseline stability, and repeatable results, making it the preferred choice for professional laboratories.

Key Highlights of LI-2707

• Advanced Double Beam Optical System :- The LI-2707 uses a double beam photometric system combined with a Czerny-Turner monochromator, ensuring excellent wavelength accuracy and minimal stray light.
• Wide Wavelength Range :- With a wavelength range of 190–1100 nm, this instrument supports both UV and visible spectrum analysis, suitable for a wide variety of applications.
• User-Friendly Touch Screen :- The 8-inch color touch screen allows smooth wavelength setting, method selection, and real-time monitoring without the need for external software.

High Accuracy & Stability

Designed for critical analysis, the LI-2707 offers:

• Wavelength accuracy of ±0.5 nm
• Wavelength repeatability of ≤0.2 nm
