Scrape testing device to characterize sample formulations

Abstract

Devices for scrape testing a sample include: a sample holder for holding the sample; a scraping blade assembly system for testing the physical characteristics of the sample that include a blade assembly, a propulsion system for moving the blade assembly relative to the sample holder, and a force sensor for measuring the force that the blade assembly experiences when scraping against the sample. Methods include placing a sample in a scrape testing device that includes a sample holder for holding the sample; a scraping blade assembly system for testing the physical characteristics of the sample that include: a blade assembly, a propulsion system for moving the blade assembly relative to the sample holder, and a force sensor for measuring the force that the blade assembly experiences when scraping against the sample; and operating the testing device and determining at least one force measurement during movement of the blade assembly.
