Macylab M-2800S UV-Vis Spectrophotometer

Key Features

• Double Beam Optical System: Splits the light path to simultaneously measure the sample and reference. This design actively compensates for light source fluctuations, improving baseline stability (0.0003A/h @500nm) and minimizing background noise for long-term measurements.
• Adjustable Spectral Bandwidth: Features five selectable bandwidth options (0.5, 1.0, 2.0, 4.0, and 5.0 nm). This accommodates specific resolution requirements for various testing standards and chemical analyses.
• 10-Inch Touch LCD Screen: Allows users to configure testing parameters, establish standard curves, and view analytical graphs directly on the large display without requiring a connected computer.
• Comprehensive Software Functions: The onboard software supports quantitative measurement, kinetic testing, multi-wavelength determination, full-band or segmented wavelength scanning, and specific DNA/protein purity analysis.
• Flexible Data Management & PC Control: Retains measurement parameters and test data even after powering down. It features a USB interface for outputting measurement data directly to a printer and supports optional PC control for expanded data manipulation.

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.
