Company

Absorbance and transmittance measurements are widely used in biology, chemistry, biochemistry, molecular biology, and other scientific fields to identify or quantify compounds and monitor changes in samples.

Many applications, however, rely on only one or a few specific wavelengths. A flexible measurement system can provide the required optical measurements without requiring a full-spectrum spectrophotometer, while allowing testing capabilities to evolve as research and applications change.

Flexible Absorbance Measurement with ABSOR.B™

ABSOR.B™ is a modular absorbance and transmittance meter designed to perform measurements at application-specific wavelengths.

Operating as a discrete spectrophotometer, ABSOR.B™ uses interchangeable optical cartridges that allow users to select the wavelengths relevant to their applications and add new wavelengths as testing requirements evolve.

How the Technology Works

ABSOR.B™ uses interchangeable emission and reception optical cartridges with specific wavelengths. Users select and plug in the appropriate cartridges according to their measurement requirements.

Different sample holders accommodate 10 mL, 4 mL and 1 mL vials, cuvettes, and PCR tubes. Experimental data is acquired, organized, and analyzed through the Soft Matter Analytics™ software.

What This Enables

Absorbance and transmittance measurements at selected wavelengths
Selection of optical configurations for specific applications
Addition of new wavelengths as research needs evolve
Adaptation to different sample formats and volumes
Monitoring of absorbance changes over time
Expansion to multiple independently operated instruments
Centralized acquisition and analysis of experimental data

Potential Applications

ABSOR.B™ can support applications requiring absorbance or transmittance measurements at specific wavelengths, including chemical and biochemical assays, reaction kinetics, enzyme activity monitoring, compound identification and quantification, concentration measurements, and other laboratory or industrial testing applications.

Technology Readiness

ABSOR.B™ is a commercially available modular absorbance and transmittance meter. Its interchangeable optical cartridges, sample holders, and scalable instrument architecture allow testing configurations to be adapted and expanded as applications and projects evolve.

Partnership Opportunities

We are interested in connecting with research and industry partners exploring applications where flexible absorbance and transmittance measurements at specific wavelengths could support R&D, product development, process monitoring, or Quality Control.
