Calibrated rare earth oxide doped sintered PTFE polymer disc 8 mm thick x 58 mm diameter within a sealable container suitable for NIR abscissa standardization. Standard suitable for 60 mm NIRA II spinner.
Set of 4 calibrated reflective sintered PTFE polymer discs 8 mm thick x 58 mm diameter within sealable containers nominally 25, 50, 60, 80% reflective suitable for NIR Pharmacopeia system verification. Standards suitable for 60 mm NIRA II spinner.
This mirror is required to verify the specular re ectance calibration of PerkinElmer and Non-PerkinElmer re ectance accessories. The aluminum mirror with magnesium uoride coating is a secondary standard and is calibrated according to GLP regulations in the wavelength range 250 to 2500 nm and includes spectral data on convenient transfer media for %RC re ection correction.
