Suitable for all industries (pharmaceutical, food, chemical, cosmetic, biotechnology, etc). Pre-sterilised versions available. Length 1000 or 500 mm, diameter 21 mm.
Available for many of the commonly used colour scales, these kits are a convenient means of ordering the complete range of equipment required. Each system includes:
•A visual comparator instrument which brings the sample and colour standards into the same field of view for more accurate colour matching
•A selection of colour standards - stable-coloured glass filters in test discs, which have been pre-calibrated to give direct readings over set measuring ranges
•A standardised bench top light source to ensure constant and uniform lighting conditions for colour matching and therefore consistent and accurate readings
•Glassware of the appropriate type and path length
A series of spectrophotometric colorimeters for colour grading of light transmitting samples. Each version of the PFX195 includes a selection of standard colour scales that is used in a specific industry sector; additional scales can be added as optional upgrades. Results can also be displayed in terms of spectral data and CIE values. Details of the most popular PFX195 versions are shown below. Versions that include FAC Colour, Klett Colour (blue filter KS-42), Hess-Ives Colour Units, Yellowness Index, US Naval Stores Rosin, Chinese Pharmacopoeia, ICUMSA Colour and Pfund/Honey are also available.
Many microbiology products from Merck are “in vitro diagnostic medical devices” (IVD) according to the directive 98/79/EC of the European Parliament and of the Council of 27 October 1998 and fulfill the requirements for CE marking.
Two spectrophotometric colorimeters for objective colour analysis of oils, chemicals, fuels and other transparent products. The PFX880 instruments are rugged colorimeters with fabricated steel housings, which function equally as QC instruments within the laboratory or on 24-hour operation in a production environment. An integrated heater unit is available as a factory fitted option for melting solid samples such as fats and waxes and preventing them from solidifying in the cell. Each instrument features a long sample chamber for cells up to 153 mm (6”) path length, ensuring precise colour measurement even with unsaturated samples such as solvents and white oils. The accuracy and repeatability of the colour data provided by these colorimeters ensures consistency in colour measurement, giving processors the confidence needed to make important decisions regarding raw materials and refining operations.
