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 color touch screen which offers a choice of different languages and has 9 ready-to-use protocols.
The is suitable for a broad range of applications including:
Working with drops of sample as small as 1 µL can be extremely challenging. The surface/volume ratio is so low that in laboratories with low humidity evaporation during handling of the sample can have a noticeable effect on sample volume and this can effect concentrations. In order to avoid this the sample drop is compressed and surrounded when closed greatly reducing evaporation and increasing the reliability of the measurement. The patented optical system of the Colibri delivers excellent photometric accuracy at better than 1%, this is 2 to 3 times better than other popular instruments on the market.
In some other spectrophotometers placing the sample in the sample area can be problematic, as the column does not form perfectly. For example, concentrated protein extracts or if the hydrophobic coating of the sample area is not in perfect condition. The sample area of the Colibri is flat and has a permanent hydrophobic coating. The sample is always easy to pipet, always perfectly placed and no reconditioning is ever needed.
The Colibri is typically 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, convenient operation in case 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,
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, the instrument internal memory will last for a lifetime. 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 convenient format. Alternatively, reports can be saved on a USB memory stick for further processing on a lab computer.
