Sample types can be: Lacquers – Oils – Solutions – Suspensions – Fats – Fatty acids – Resins – Syrups – Waxes<\/em><\/p>\n To this end, the ASTM<\/strong>, for example, has clearly defined the assignments of the visual standards<\/a> to the color values measured on the device. In principle, all three color numbers are measured in cuvettes or ISO vials in total transmission<\/a> (TTRAN)<\/strong>, as the samples are transparent liquids. Semi-solid substances such as waxes or Vaseline are tested in a molten state. <\/p>\n [\/et_pb_text][difl_imagecarousel item_desktop=”1″ item_tablet=”1″ loop=”on” autoplay=”on” arrow=”on” ic_content_background_bgcolor=”RGBA(28,28,28,0.8)” arrow_color=”#FFFFFF” arrow_background=”#073466″ caption_padding=”10px||||false|false” _builder_version=”4.24.3″ _module_preset=”default” locked=”off” global_colors_info=”{}”][difl_imagecarouselitem image=”https:\/\/hunterlab.de\/wp-content\/uploads\/2024\/04\/Farbmessung-von-gelblicher-Fluessigkeit-HunterLab-Vista-1920w.jpg” caption=”Measurement of yellowish liquid in 10 mm glass cuvette.” vertical_align=”flex-end” ic_button_button_url_new_window=”1″ _builder_version=”4.24.3″ _module_preset=”default” caption_text_align=”center” caption_text_color=”#FFFFFF” background_enable_color=”off” global_colors_info=”{}”][\/difl_imagecarouselitem][difl_imagecarouselitem image=”https:\/\/hunterlab.de\/wp-content\/uploads\/2024\/04\/Farbmessung-von-roetlicher-Fluessigkeit-HunterLab-Vista-1920w.jpg” caption=”Color measurement of red liquid in 50mm glass cuvette.” vertical_align=”flex-end” ic_button_button_url_new_window=”1″ _builder_version=”4.24.3″ _module_preset=”default” caption_text_align=”center” caption_text_color=”#FFFFFF” background_enable_color=”off” global_colors_info=”{}”][\/difl_imagecarouselitem][difl_imagecarouselitem image=”https:\/\/hunterlab.de\/wp-content\/uploads\/2024\/04\/Vista-Anwendung-heisse-Fluessigkeiten-Peltier-w-2880w.png” caption=”Vista with heating element for solid samples that are measured in a liquid state.” vertical_align=”flex-end” ic_button_button_url_new_window=”1″ _builder_version=”4.24.3″ _module_preset=”default” caption_text_align=”center” caption_text_color=”#FFFFFF” background_enable_color=”off” global_colors_info=”{}”][\/difl_imagecarouselitem][difl_imagecarouselitem image=”https:\/\/hunterlab.de\/wp-content\/uploads\/2024\/04\/Vista-APHA-EP-Farbzahl-Farbmessung-an-Kleinstmengen-Pharma-1920w.jpg” caption=”Color measurement of yellowish liquid in micro cuvette.” vertical_align=”flex-end” ic_button_button_url_new_window=”1″ _builder_version=”4.24.3″ _module_preset=”default” caption_text_align=”center” caption_text_color=”#FFFFFF” background_enable_color=”off” global_colors_info=”{}”][\/difl_imagecarouselitem][\/difl_imagecarousel][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.16″ background_size=”initial” background_position=”top_left” background_repeat=”repeat” locked=”off” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_text _builder_version=”4.24.3″ text_font_size=”18px” header_3_font=”||||||||” background_size=”initial” background_position=”top_left” background_repeat=”repeat” global_colors_info=”{}”]<\/p>\n The Vista color measurement device<\/a> is ideal for measuring these color numbers. This is a double-beam spectrophotometer<\/a> with diffuse\/0° measuring geometry<\/a><\/strong>, which can be used to measure liquid samples (and transparent solid samples if required) in transmission<\/a> with simple handling. This device can be used to examine samples with all layer thicknesses from 10 mm to 50 mm<\/strong>. The selection of the colour number<\/a>, together with the examined layer thickness, is referred to as the index. After the measurement, the color values of the sample and various color scales and indices, in particular the APHA, Gardner and Lovibond® indices<\/strong>, can be read off.<\/p>\n Depending on the number of colours, different indices are available for cuvettes, ISO vials, microcuvettes and ultra-microcuvettes with path lengths from 10 mm to 50 mm. This means that samples can be reliably measured in various simple or acid- or temperature-resistant plastic or glass cuvettes with the appropriate cuvette holders. The Vista offers the special option of calculating the output value for a coating thickness other than the measured one in order to obtain values in accordance with ASTM, DIN and ISO standards<\/a><\/strong>. This often eliminates the need to purchase expensive special cuvettes. <\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.24.3″ background_color=”#e4e6ce” background_size=”initial” background_position=”top_left” background_repeat=”repeat” custom_padding=”|10px||10px|false|true” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_text _builder_version=”4.24.3″ text_font_size=”18px” header_3_font=”||||||||” background_size=”initial” background_position=”top_left” background_repeat=”repeat” custom_margin=”||80px||false|false” custom_margin_tablet=”||20px||false|false” custom_margin_phone=”||20px||false|false” custom_margin_last_edited=”on|tablet” locked=”off” global_colors_info=”{}”]<\/p>\n Read in our current HunterLab NEWS magazine how we measure color numbers with the Vista transmission<\/a> colorimeter, what to look out for in terms of sample handling and what alternatives are available.
