ODcube+ is a fixed wavelength optical detector with the same technology as the ODcube, capable of symultaneous detection of up to 3 wavelengths.

The system is highly bio- and chemically compatible and features a flow cell with a 10 mm light path and only 2 µL of detection volume. It comes with versatile, easy to use ODread software. Due to the robust design and innovative low power LED and laser technologies the ODcube requires only a small amount of power, making it ideal for field instrumentation as well as point-of-care applications. The ODcube can be installed into your instrument as we are happy to provide you with the serial communication protocol for effortless OEM integration. The fine-tuned system with 16-bit detection and programmable gain amplification won't let you down!


Integrated PEEK flow cell.

High precision CNC milled flow cell features 10 mm light path for high precision analysis and less than 2 uL of internal volume for flow resolution. Essi's innovative proprietary technology.

Chemical compatibility.

All wetted materials are highly inert: quartz glass, PEEK, PTFE and fluoropolymers.

High pressure.

The ODcube can withstand up to 50 bar (as standard or up to 300 bar upon request).

High sensitivity, low limit of detection, low noise.

Essi's innovative 16 bit LED-based detection technology in combination with high-precision flow cell allows detection comparable to HPLC detectors.

Small and affordable

...at a fraction of a price and space required compared to a classic detection system.



ODcube+ comes with ODread+ software - for intuitive work with your ODcube+.

For the convenient data handling the software saves the files in a format that can be directly opened with notepad or Excel!

Other wavelengths are available upon request.

*High pressure option: increases the maximum pressure from 50 bar to 300 bar, internal 0.5 mm I.D. tubings are replaced by 100 um I.D. tubings, which increases the system's back pressure and reduces singal tailing significantly.
