Adjustable Reflectance Preform Holder
Measures preforms with shaft diameter from 15 mm to 40 mm. The length of the straight shaft above the preform threads should be at least 50mm in order to completely cover the port.
Adjustable Transmission Preform Holder
Measures preforms with shaft diameter from 10mm to 40mm. The length of the straight shaft above the preform threads should be at least 50mm in order to completely cover the port.
Used for compressing fibers into a compact mass to permit repeatable color analysis. Available and sold separately are:
Reflectance Sample Shelf with Light Cover
For the reflectance measurement of powders, granules and semi-solids held in a rectangular cell (below). Cells purchased separately.
Optically clear glass cell with depth of 10mm, 20mm or 50mm; 55mm width x 57mm height. (Listed on front page)
Semi-Micro Powder Holder
Permits the reflected color measurement of as little as 0.4cc of packed powder. Powder is placed in the powder holder and is backed with the white plunger.
Flow Through Cell & Holder
A 51 mm (2 inch) diameter optically clear flow through glass cell with a path length of 10 mm, 20 mm or 50 mm.
Cell holder that is mounted in the transmission compartment for supporting a flow cell. Cell purchased separately.
Transmission Cell (Rectangular)
13-8573-40 (10 MM)
04-4592-00 (20 MM)
13-8573-20 (50 MM)
Provides consistent placement of 10 mm, 20 mm, 33 mm or 50 mm path length transmission cells – purchased separately.
Transmission Spill Tray & Cell Holder
Permits transmittance measurement of liquids using rectangular transmission cell (below). Cells purchased separately.
Cell Holder Base Assembly
This Cell Holder Base Assembly with one or more clip-on holders (ordered separately) centers macro, semi-micro and ultra-micro, as well as other precision analytical cell holders in the transmission compartment of HunterLab sphere instruments. This assembly ensures repeatable transmission color measurements of very small volumes of clear liquids. Select one or more of the available precision cell holders by matching cell holder specifications with the desired glass or plastic analytical cells. Analytical cells are purchased separately by the customer.
Holds transparent film, glass or plastic in position for total or regular transmission measurement.
The UltraScan VIS easily measures both reflected and transmitted color as well as transmission haze and meets CIE, ASTM and USP guidelines for accurate color measurement. UltraScan VIS uses diffuse/8° geometry with automated specular component inclusion/exclusion. For transmission measurement, the use of a robust CIE-conforming sphere instrument (TTRAN Total Transmission mode) effectively negates the effects of minor scattering typically found in transparent samples.
Because of its exceptional inter-instrument agreement and long-term stability, you can be confident that differences between measurements are due to product color changes, not instrument variability. Materials on the borderline of accepted tolerances will not be unnecessarily rejected.
