SCT-D Stress Crack Tester (26 Positions) – For testing the Stress Crack Resistance of Carbonated Soft Drink Bottles
The AT2E SCT-D Stress Crack Tester is designed to test the internal stress in bottle base and for determining the stress crack resistance of blow-molded PET carbonated soft drink bottles by measuring the propensity for base cracking upon exposure to an aqueous sodium hydroxide solution under a controlled environment, so that to estimate the long term behavior of bottles.

Many of the defects found in PET container preforms can be detected by using the PL-2. Preforms viewed in polarized light exhibit a colored birefringence pattern.
The birefringence is a result of the polymer flow lines (molecular orientational strain) produced during the injection moulding process.
The colored pattern observed with preform held at 45° to the polarizing axis is known as an isochromatic fringe indicating the amount of birefringence.
Stress introduced during the manufacture of glass components has an important effect on the strength of the product. This effect can be detrimental or beneficial in that it may contribute to failure in service, or to an increase in strength. It is clearly important for quality control to monitor the residual stresses that are present.
This aphrometer checks the evolution of the pressure during the secondary fermentation.
Remove one bottle without cap from the filling machine and put the aphrometer on the bottleneck.
The permanent aphrometer will remain on the bottleneck during the entire secondary fermentation.
The simplified Aphrometer is designed to check the pressure and the vacuum in the bottles of still wine (Bordeaux bottles, Burgundy bottles).
Thanks to its sting this pressure gauge pierces corks and some synthetic corks, but it cannot pierce crown caps or all other metallic shutters.
The cork ensures the airtightness.
This aphrometer is designed to check the pressure during the secondary fermentation.
This Champagne pressure gauge checks instantaneously the pressure in the bottles topped on with a crown cap with or without plastic shutter.
A gasket ensures the airtightness between the aphrometer and the crown cap.
The “PVG” is used to measure pressure or vacuum of can or bottle.
Simply place the sample under the entity manometer or vacuum meter and lower the lever. Then read the value.
