Features: Fast measurements by NANOCOLOR® barcode technology: • Fully automatic, instant cuvette detection by the built-in laser scanner allows simple and fast routine analysis. • Selection of the test method and suitable wavelength, the actual measurement and storage of the measurement results are carried out automatically without having to use any other key. Measurement without cuvette slot cover: • The modern designed optics is insensitive to external light and allows straightforward measurements. Everything at a glance: • The modern, illuminated graphic display with user guidance shows all the important data at a glance. Pre-programmed tests and photometric basic functions • More than 100 pre-programmed tests with over 200 analysis programmes • Straightforward call-up of all photometric basic functions, such as absorbance, factor, standard, transmission and kineti Self-explanatory user guidance: • All tests and menu items can be activated fast and easily. • The photometer can be operated without any complex and time-consuming training. Manual with test instructions, presented as pictograms: • Safe test procedures without complex instructions Highly accurate measurements by high-quality optical components: • The high-precision optic warrented accurate results IQC according to ISO 9001 with NANOCONTROL NANOCHECK: • Conformance to requirements of internal quality control (IQC) and protection towards supervisors and authorities. • Fast and easy control of photometric accuracy of the NANOCOLOR® 500 D with NANOCONTROL NANOCHECK by the user himself. Documentation of results in accordance to GLP • Individual entries of sample number, sample location, user and dilution • Clear memory management: • GLP-conform storage of the measured results with all supplementary information such as date, time, sample number, sample location, user and dilution. • Fast and easy access to stored results and data sets. Convenient export of data: • Easy transfer of measured results and spectra to various common PC formats (e.g. MS Excel). • Direct print-out of measured data with the NANOCOLOR® thermal printer (Cat. No. 919 16). No cuvette adapter required: • Round tubes (16 mm OD) and rectangular cuvettes (10, 20, 50 mm) can be used in the universal cuvette slot without any adapter. • Small accessories are not required Programmable for user defined applications: • Free programming of up to 100 user defined methods Fast photometer update - free of charge: • At any time, stay up-to-date by easy programme updating via Internet/PC In the field and in the lab: • The standard built-in, robust high-performance battery with charge regulator allows continuous operation at 220V (110V) and up to 3000 on-site mains-independent measurements. The battery charge status is shown in the graphic display. In the power saving mode, the photometer switches off automatically after 10, 20… 120 min.
