Designed for Efficient Daily Laboratory Testing

Whether measuring DNA, RNA, proteins or other biological samples, the Welso Micro Spectrophotometer provides a simple workflow from sample loading to result analysis.

Simply place a small sample on the measurement pedestal, close the arm and start the measurement. Results can be viewed directly on the touchscreen without requiring a separate computer.

For users who require conventional cuvette measurements, the WNA-1 model provides an additional cuvette detection function, including OD600 measurement.

Key Features

Microvolume Measurement with Minimal Sample Consumption

Only 0.5–2.0 μL of sample is required for microvolume measurement. This makes the instrument particularly suitable for precious or limited biological samples.

The sample pedestal design allows users to perform measurements without routine dilution procedures for many applications, helping simplify daily laboratory workflows.

Wide UV-Vis Wavelength Range

The instrument supports a wavelength range of 180–910 nm, allowing measurement across a broad range of UV and visible light applications.

This provides flexibility for the analysis of:

● DNA

● RNA

● Oligonucleotides

● Proteins

● Enzyme samples

Other biological and biochemical samples

Fast Measurement

With a measurement time of less than 6 seconds, the spectrophotometer allows laboratories to obtain results quickly and efficiently.

The fast measurement workflow is particularly useful for laboratories handling multiple samples during routine molecular biology or protein analysis.

7-Inch Touchscreen Operation

The instrument is equipped with a 7-inch touchscreen and Android operating system.

Users can perform measurements, review results and manage data directly on the instrument, reducing dependence on an external computer.

The graphical interface makes it easier to review spectral curves and measurement results during daily operation.

Integrated Xenon Flash Lamp

The micro spectrophotometer uses a xenon flash lamp as its light source.

Compared with conventional continuously operating lamps, xenon flash technology provides rapid measurement capability and supports long-term laboratory use.

The lamp design is suitable for repeated measurements in routine laboratory workflows.

Reliable Data Storage and USB Export

Measurement data can be stored directly on the instrument and exported through a USB interface for further analysis and record management.

The instrument can support the output of:

● Measurement data

● Spectral results

● Image files

● Excel-compatible data files

This makes it easier to transfer experimental results for reporting, documentation and further analysis.

No Computer Required for Routine Measurement

The instrument can perform measurement and store data independently.

For routine applications, users do not need to connect the spectrophotometer to a computer during measurement.

This helps simplify laboratory installation and makes the instrument suitable for laboratories that require a compact and independent analytical solution.

Optional External Printer

An external printer is available as an optional accessory.

This can be useful for laboratories that require printed measurement records or immediate result documentation.

WNA-1S and WNA-1: Which Model Should You Choose?

WNA-1S

The WNA-1S is designed primarily for microvolume spectrophotometric measurement.

It is suitable for laboratories focusing on:

● DNA quantification

● RNA analysis

● Protein concentration measurement

● Microvolume biological samples

● Routine molecular biology applications

The WNA-1S provides a wavelength range of 180–910 nm and supports microvolume measurements with sample volumes of 0.5–2.0 μL.

WNA-1

The WNA-1 provides the same microvolume measurement capability while adding cuvette measurement and OD600 detection.

The cuvette measurement function makes it suitable for laboratories that require both microvolume and conventional spectrophotometric analysis.

In addition to the 180–910 nm measurement range, the WNA-1 supports:

● Cuvette measurement

● OD600 measurement

● Additional visible-light absorbance applications

The WNA-1 is therefore a more versatile option for laboratories with broader analytical requirements.

Applications

The Welso Micro Spectrophotometer can be used in a variety of laboratory applications, including:

Nucleic Acid Analysis

Measure DNA and RNA concentration and assess nucleic acid samples for molecular biology workflows.

Typical applications include:

● DNA quantification

● RNA quantification

● Oligonucleotide analysis

● PCR sample preparation

● Sequencing sample preparation

Protein Analysis

The instrument supports protein concentration measurement across different protein detection ranges.

Applications may include:

● Protein quantification

● Enzyme analysis

● Biochemical research

● Protein sample preparation

Microbiology and Cell Analysis

With the cuvette and OD600 function available on the WNA-1 model, the instrument can also be used for applications involving microbial culture measurement.

OD600 measurement is commonly used to monitor the optical density of bacterial or cell suspensions.

Research and Educational Laboratories

The compact design and integrated touchscreen operation make the instrument suitable for:

● Molecular biology laboratories

● Biotechnology laboratories

● Research institutes

● Universities

● Pharmaceutical laboratories
