A New and Revolutionary Spectrophotometer

Feb 07 2018 Read 364 Times

MACHEREY-NAGEL’s NANOCOLOR® VIS II spectrophotometer will revolutionise its users’ daily laboratory work, combining premium high-tech instruments with outstanding usability. With its intuitive, icon-based menu guidance, this innovative photometer can be used like a smartphone or tablet. The clearly arranged, high-resolution touch screen display makes daily measurement routines a real pleasure.

On the technical side, the NANOCOLOR® VIS II impresses with clever mechanics and optics. It features the well-known and proven barcode technology for a rapid measurement of our NANOCOLOR® tube tests, while measuring NANOCOLOR® standard tests or pre-programmed methods is easily done as well.

The entirely new scan menu allows operators to scan in real time at different resolutions, but also to perform in depth analyses of the scans. The user can highlight peaks and valleys, add and subtract scans and generate high quality images with no additional software or complex programming.

As a unique aspect of all MACHEREY-NAGEL spectrophotometers, the NANOCOLOR® VIS II also features an integrated nephelometric turbidity (NTU) measurement function; however, it has been significantly enhanced in this instrument. An automation of this measurement is the integrated NTU-Check function, allowing the detection of interfering turbidities with every tube test measurement - a huge safety aspect for the users’ measurement results.

To make life in the lab easier, MACHEREY-NAGEL recently launched the brand new NANOCOLOR® FP-200 sipper module, which is directly operated via the NANOCOLOR® VIS II spectrophotometer which is more than capable of analysing aggressive samples.

Dealing with large sample numbers in photometric analysis often requires a lot of time and resources due to the preparation of the samples in different cuvettes and the frequent changes of the cell in the photometers. The combination of the NANOCOLOR® VIS II with the NANOCOLOR® FP-200 sipper module and a flow cell (2 mm, 10 mm or 50 mm) reduces the work effort drastically when a high number of samples is analysed.

With this peristaltic pump, a constant amount of liquid is pumped through a flow cell and the measurement is started automatically in the photometer. Besides conservation of resources, the NANOCOLOR® FP-200 can also increase the measuring accuracy. One reason for that are the same optical conditions for zero and sample measurement. Errors due to optical differences between different cuvettes are avoided, because all solutions to be analysed flow through the same cuvette.

Unwanted contact with chemicals is effectively avoided with the sipper module, because there is no need to pour samples into the cuvette. The hoses and the sipper module itself are highly resistant against organic solvents and aggressive liquids. Special tubes for extremely aggressive chemicals are readily available.
