The Macylab UL-2000 is a compact, PC-controlled micro-volume UV-Vis spectrophotometer engineered for the quantitative and qualitative analysis of biological samples. Operating in the 190nm to 850nm wavelength range, it is primarily utilized for measuring nucleic acids, proteins, and bacterial concentrations.
Equipped with a long-life Xenon flash lamp and a 3648-pixel linear CCD array detector, the UL-2000 performs rapid analytical scans without the need for lamp warm-up time. It requires a minimum sample volume of just 0.5μL, allowing researchers to conserve precious samples while avoiding the manual dilution steps typically required by traditional cuvette-based spectrophotometers.
Key Features
Micro-Volume Analysis: Allows direct testing of highly concentrated samples with a minimum volume of 0.5μL. Most samples can be measured directly without prior dilution, reducing preparation errors and saving time.
Instant Testing (No Warm-Up): Utilizes a high-intensity Xenon flash lamp that flashes only during measurement. This eliminates the standard 15-minute warm-up time required by traditional deuterium/tungsten lamps and significantly extends the light source’s lifespan.
Wide Dynamic Range: Capable of measuring double-stranded DNA (dsDNA) concentrations ranging from a lower limit of 2 ng/μL up to an upper limit of 15,000 ng/μL, covering a broad spectrum of molecular biology applications.
Durable Sample Pedestal: The micro-volume measurement pedestal is constructed from 304 stainless steel and quartz, providing a robust, easy-to-clean surface that prevents sample cross-contamination.
Dual Measurement Modes: Supports both micro-volume drop testing via the adjustable optical path (1mm / 0.2mm / 0.05mm) and standard testing via a cuvette slot (up to 10mm optical path).
Compact & Portable Design: Weighing only ≤2.5kg with a footprint of 200 × 130 mm, the instrument is highly space-efficient and easily transportable for on-site testing environments.

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. Unlike traditional spectrophotometers that use deuterium or tungsten lamps requiring a 15-minute warm-up, the UL-2000 is equipped with a Xenon flash lamp. It is ready to test immediately upon powering on.
For most applications, dilution is not required. The UL-2000 features a wide dynamic absorbance range (0.005 – 300A, 10mm equivalent) and can directly measure dsDNA concentrations up to 15,000 ng/μL using its adjustable micro-volume optical path.
The sample pedestal is made of 304 stainless steel and quartz. You can easily clean it by simply wiping the upper and lower optical surfaces with a clean, dry, lint-free laboratory wipe between sample measurements to prevent cross-contamination.
Yes. Alongside the micro-volume pedestal, the instrument supports cuvette optical distances of 10mm, 5mm, 2mm, and 1mm, allowing for traditional cell culture density (OD600) and dilute sample measurements.
Yes. The UL-2000 relies on a PC connection for operation. The instrument connects via a data line, and the provided software interface on your computer controls the scanning process, data analysis, and report generation.
