Colibri is ready for use straight out of the box and measurement takes less than 5 seconds. The on-board software is operated via a colour touch screen, which offers a choice of different languages and 9 ready-to-use protocols.  

The spectrophotometer is suitable for a broad range of applications, including:

  • Determination of nucleic acid concentration and purity of nucleic acid samples without dilution
  • Density of fluorescent dye labelling of nucleic acid microarray samples
  • Purified protein analysis (A280)
  • Bradford, BCA and Lowry assays for protein quantification
  • Spectrum measurement and quantification of fluorescently labelled proteins, conjugates, and metalloproteins
  • Cell density
  • General UV-Vis spectrophotometry

Highlights

Total reliability and reproducibility

Working with drops of sample as small as 1 µL can be challenging: the surface/volume ratio is so low that, especially in laboratories with low humidity, evaporation during handling and quantification of the sample can have a noticeable effect on sample volume and, hence, concentration. In order to avoid this in the Colibri, the sample drop is compressed and surrounded when closed, greatly reducing evaporation and increasing the reliability of the measurement. Furthermore, the patented optical system of the Colibri delivers an excellent photometric accuracy: better than a 1%, that is, 2 to 3 times better than other popular instruments in the market.

Easy sample handling and measurement

In some other spectrophotometers placing the sample drop in the sample area can be problematic, as the column does not form perfectly in the case of some samples (for example, concentrated protein extracts) or if the hydrophobic coating of the sample area is not in perfect condition. However, the sample area of the Colibri is flat and has a permanent hydrophobic coating, so the sample is always easy to pipet, always perfectly placed and no reconditioning needed. 

 

 

Total operational flexibility

The Colibri is usually operated via its touchscreen, but if that's not your style, there are other options: alternatively, you can use softkeys, or you can connect a standard USB keyboard and mouse for quick and convenient operation, e.g. if you need to enter long sample names. The software is available in 10 languages: English, Chinese, Russian, Spanish, Portuguese, German, French, Italian, Polish and Turkish, if you prefer to use the software in your native language.

Save, print or export your results

Measurement data is organized and saved according to the project and can be retrieved at any time. With enough internal memory to hold more than 100.000 measurements, this capacity will last for the lifetime of the instrument. Samples can be named individually or automatically for later identification and reporting. Reports are available on an optional external printer or as CSV files. The printout is 112 mm wide, allowing for a layout in a convenient format. Alternatively, reports can be saved on a USB memory stick for further processing on a lab computer.
