Child Resistant Closure Torque Tester for HDPE Bottles

Torque tester with push-and-turn fixture that measures the opening torque of child resistant caps on HDPE bottles. Used by pharma and agrochemical packaging companies for closure qualification.

Specification

The bottle is held in a clamp while the fixture presses down and turns the cap at a set axial force. Peak opening torque and cap pop-off are recorded. The tester helps ensure caps are secure while still being accessible to adults.

Features

• Axial load applied by spring or air cylinder
• Torque range 0 to 3 N-m
• Adjustable push down force up to 100 N
• Rubber-lined bottle clamp
• Peak hold with memory
