Encapsulated Gray Scale Standards

Gray scale diffuse reflectance standards, encapsulated to meet USP 1119 standards

Avian Technologies offers encapsulated gray scale and wavelength standards designed to meet USP 1119 specifications. These standards are identical to our Fluorilon™ standards, except with the Fluorilon™ encased in a Delrin™ holder with a 2” diameter BK-7 window.

The size of both the gray scale and wavelength standards is identical to enable fixturing for most instruments designed to measure pharmaceutical on-line processes.The wavelength standard has the same components as the National Institute of Technology’s SRM-1920a, with a small amount of an inert, spectrally non-absorbing binder. Unlike sintered equivalents of SRM-1920a, this standard exhibits no peak shifting and is both durable and stable.

Each standard has a small, re-sealable port in the top to allow for conditioning in a controlled humidity environment.

Standards & targets are available individually, or in sets of four or eight.
