Ultramicro Spectrophotometer YR07039

Its 7-inch LCD touchscreen provides an intuitive interface and allows capturing the test screen to record results. The pulsed xenon lamp, with a specified lifespan of over 10⁹ flashes, reduces the frequency of light source replacement. Additionally, the high-sensitivity CMOS detector enables full spectrum analysis in approximately 3 to 8 seconds.

The device offers quantification modes for nucleic acids and proteins, kinetic monitoring, spectral scanning, and photometric measurement, including bacterial growth reading OD600. Its integrated Linux system, expandable local storage via SD card, and USB export facilitate independent use in molecular biology, biochemistry, microbiology, and pharmaceutical research laboratories.

Market Price

The price of an ultramicro spectrophotometer depends on the brand, features, software, accessories, and after-sales service. As a reference, microvolume devices are published from approximately USD 4,550 to USD 14,710; some models with touchscreen and applications for life sciences appear around USD 14,000. These values serve as market references and may vary by country, taxes, shipping, and configuration.

Frequently Asked Questions

How much sample does the YR07039 need?
It requires between 1.0 and 2.5 μL, making it useful when working with scarce or hard-to-obtain samples.

What types of analysis can it perform?
It includes quantification of nucleic acids and proteins, kinetic monitoring, spectral scanning, and photometric measurement, including OD600 reading.

Does it need to be connected to a computer to operate?
According to available information, it has an integrated Linux operating system, touchscreen, and local storage, so it can perform measurements without continuously relying on a computer. Data can be exported via USB.

How long does a full spectrum measurement take?
The specification indicates an approximate time of 3 to 8 seconds, which may depend on the analysis mode and sample conditions.

Advantages and Considerations

Among its advantages are the low sample volume, fast reading, variety of analysis modes, and touchscreen operation. The long-lasting xenon lamp can reduce maintenance interventions, while USB export and SD card expansion help organize results.

As a consideration, microvolume measurements require careful preparation: residues, bubbles, or poorly homogenized samples can affect the reading. Additionally, for very diluted samples or analyses requiring specific sensitivity, it is advisable to confirm that the range and method of the device are suitable for the laboratory protocol. The available specification does not specify the spectral range, photometric accuracy, or detection limits; it is recommended to request these before purchase.

Product Use in the Field

In a molecular biology laboratory, the user deposits a small aliquot of DNA or RNA in the measurement area to determine concentration and purity before PCR, sequencing, or other subsequent analyses. In biochemistry, it can be used to quantify proteins; in microbiology, to monitor bacterial growth via OD600. Kinetic monitoring and spectral scanning also allow observing changes in samples during assays and investigations.

Usage and Maintenance Recommendations

Clean the measurement area before and after each reading following the manufacturer's manual, and use lint-free material to avoid residues. Homogenize the sample and ensure it does not contain bubbles before measuring. To obtain comparable results, keep the method, sample type, and measurement conditions constant, and use appropriate blanks for each assay.

Periodically export data and screenshots via USB, and keep a backup copy of important results. Before updating the software, consult the manufacturer's instructions and confirm the compatibility of the USB unit. For routine use, also check the calibration and quality control needs of the laboratory protocol.
