The Macylab V-1500 is a microprocessor-controlled visible spectrophotometer designed for precise quantitative analysis in the visible and near-infrared spectral range of 320nm to 1100nm. Powered by an imported Tungsten lamp and a silicon photodiode detector, it provides a narrow 2nm spectral bandwidth for reliable resolution of adjacent absorption peaks.
Unlike manual entry-level devices, the V-1500 features an automatic wavelength adjustment mechanism, automatic filter changing, and a 128×64 dots LCD screen. It functions efficiently as a standalone unit for establishing standard curves and saving data, while also offering standard PC software control via USB for advanced analytical requirements in routine laboratory environments.
Key Features
Automated Optical Adjustments: Features automatic wavelength setting, auto filter changing, and one-key auto zero/100% adjustment to minimize manual operational errors.
Advanced Quantitative Capabilities: Establish standard curves using up to 10 standard samples directly on the device. Users can also input K and B factors manually to establish standard concentration values for rapid quantitative measurements.
Clear Data Visualization: The built-in 128×64 dots LCD screen allows operators to display multiple sets of measurement data, curve parameters, and standard sample points simultaneously without needing a connected computer.
Reliable Data Storage & Output: Includes a power-off save function to retain standard curve parameters and measurement data. It is equipped with a USB interface for PC control and a parallel printer port for direct printing of title bars, data, and curves.
Accommodating Sample Pool: The large sample compartment is designed to fit cuvettes with path lengths ranging from 5mm up to 100mm, providing flexibility for testing low-concentration solutions.

Applications
Water & Environmental Analysis: Accurate colorimetric determination of chemical oxygen demand (COD), ammonia nitrogen, heavy metal ions, and other water quality indicators.
Agriculture & Soil Testing: Measuring extractable nutrients and organic matter in soil, fertilizers, and agricultural products.
Food & Beverage Quality Control: Quantitative monitoring of food dyes, additives, and visual color intensity in manufacturing processes.
General Academic Research: Performing routine kinetics testing and concentration measurements in university chemistry and biology laboratories.
Who is it for?
Third-Party Testing Laboratories: Facilities handling a large volume of daily samples that benefit from automatic wavelength setting and direct PC data logging.
Academic and Educational Institutions: University research departments requiring a visible spectrophotometer with a 2nm bandwidth and curve-display capabilities for student projects.
Industrial QC Departments: Quality control labs in food, chemical, and water treatment plants needing reliable, repeatable photometric data and standard curve generation.
Why choose it?
Enhanced Resolution over Base Models: Compared to standard 4nm entry-level instruments, the V-1500 offers a 2nm spectral bandwidth and a wavelength accuracy of ±0.5nm. This provides much clearer separation of closely spaced absorption peaks.
Operational Flexibility: The system can be used as a standalone unit utilizing the LCD screen to build standard curves, or connected to a Windows PC via USB to perform continuous wavelength scanning (within the 320-1100nm range), multi-wavelength testing, and kinetics analysis.
Time-Saving Automation: The combination of automatic wavelength tuning and automatic filter changing removes the physical inconsistencies associated with turning manual mechanical dials, improving repeatability between different operators.

Packaging, Installation & Operation
Packaging & Shipping
After unpacking the instrument, compare the contents with the packing list and check that all items are present and undamaged.
Installation & Setup
Place the spectrophotometer in a suitable location away from direct sunlight, dust, corrosive gases, and strong vibrations. For stable operation, keep it away from strong magnetic or electrical fields and electrical devices that may generate high-frequency fields.
Keep the area around and underneath the instrument clear to allow adequate airflow.
Use the appropriate power cord and connect the instrument to a grounded outlet.
Initial Operation
Turn on the spectrophotometer and allow it to warm up for the recommended time before taking measurements. Follow the instrument’s operating instructions to complete any required system initialization, calibration, or wavelength verification before measurement.

FAQ (Frequently Asked Questions)
No. Standard nucleic acid and protein analysis requires ultraviolet (UV) light at 260nm and 280nm. The V-1500 is equipped with a tungsten lamp and operates in the visible spectrum from 320nm to 1100nm, meaning it physically cannot measure UV wavelengths.
No. The V-1500 can function completely independently. You can input up to 10 standard samples or manually enter the K and B factors directly through the keypad, and the standard curve will be generated and displayed on the 128×64 LCD screen.
When connected to a PC via the USB interface, the standard software allows for wavelength scanning (within the 320-1100nm range), kinetic testing (monitoring absorbance changes over time), quantitative measurements, and simultaneous multi-wavelength testing.
No. The V-1500 features a fully automatic wavelength adjustment and automatic filter changing system, eliminating the need for manual mechanical dials.
Yes, the instrument includes a general-purpose parallel printer port. You can print the title bar, measurement data, curve parameters, standard sample points, and the generated curve directly to a compatible local printer without using a PC.
