Sample Vial Holder

The Sample Vial Holder for use with the Near-Infrared Reflectance Module (NIRM) and Near-Infrared Reflectance Accessory (NIRA II) allows for multiple sizes and types of vials to be accurately and reproducibly held for diffuse reflectance measurements. The Sample Vial Holder is held magnetically in place on the accessory top plate. The variable iris of the vial holder centers the vial on the middle of the accessory window and will close down around vial eliminating stray light ensuring reproducible reflectance measurements.
