Pharmacopoeia 4003 Test Method for Polarized Stress Tester for Ampoule Bottles

Ampoule Polarized Stress Tester YLY-03SSuitable for measuring the internal stress values of various glass products such as glassware, glass measuring tools, glass containers, glass bottles for medicinal and food packaging. The instrument can qualitatively and quantitatively test the internal stress of glass, and the LCD screen can directly read the results. The design is compact and innovative, and it is widely used in pharmaceutical enterprises, glass product factories, quality inspection units and other units.

Test Principle

An instrument used to apply the principle of polarized light interference to check the internal stress of glass or the birefringence effect of crystals. Due to the sensitive color plate and the application of 1/4 waveplate compensation method in the polarization stress meter, this instrument can not only qualitatively or semi quantitatively measure the optical path difference of glass based on the interference color sequence in the polarization field, but also cooperate with CHY-B2Wall thickness gaugeIt can accurately and quantitatively measure the internal stress value of glass.

Scope of Application

Suitable for measuring internal stress values in glass measuring tools, medicinal glass bottles, oral liquid bottles, ampoules, plastic bottle preforms, quartz, gemstone products, and other glass containers.
