Penetrability Tester

Model No: Tx - PT100
Brand: Testronix Instruments

Penetrability Tester measures the force required for a hypodermic needle to penetrate pharmaceutical rubber stoppers, vial closures, and ampoule septa. This test is important for smooth needle entry during drug withdrawal or injection. It helps prevent coring, leakage, and excessive puncture force.

Testronix Instruments is a leading manufacturer and supplier of penetrability t...

Description

Built with a high-accuracy load cell and microprocessor-controlled drive mechanism, the penetrability tester applies a uniform force while pushing a standard needle into the closure. The required penetration force is captured with extreme precision and displayed digitally. 

Penetrability tester helps pharmaceutical manufacturers check closure quality, guarantee machine performance on filling lines and meet pharmacopoeia requirements. 

The computerized version enhances testing efficiency through real-time graphing, force–time plots, and automated reporting, making it ideal for quality control labs, R&D centers, and regulatory compliance testing.
