Leak Test Apparatus

IP compliance Pharmaceutical Leak Test Apparatus –  Model number 901



Yatherm Leak Test Apparatus designed as per USP/IP specification to test the packaging of tablets pouches and sachet in the pharmaceutical & food industry. This test gives the results which cannot be seen from naked eyes like cracks and hole with imperfect sealing. Yatherm Scientific offers lightweight & durable acrylic desiccators in different sizes which can handle the vacuum easily at the time of test, high-quality vacuum gauge. The compact vacuum pump according to the size of desiccators, Real-time dot matrix printer with soft-touch keypad & Alphanumeric digital display makes our leak tester more advance.


Leak Tester works on the principle of creating a negative pressure in a closed chamber which inflates the sealed pouches due to pressure and leaked pouches don’t inflate. To test the sample we place tablets sachet into the desiccator filled with Methylene blue than vacuum the desiccators for a limited time. The vacuum gauge of the Leak test apparatus is connected to a control valve that isolates the vacuum inside desiccator from the vacuum pump.


Digital timer plays an important role in the testing of tablets in leak tester which explains the capacity of handling pressure of a sealed pouch. Analysis of the test depends on the size and shape of the packet after the release of the vacuum. Yatherm Offers high-quality CE certified instruments with the best prices in INDIA. We give one year warranty for all instruments with ten years’ supply of spare parts for a better relationship with our customers.

Working of Leak tester

Leak test apparatus is very easy to operate the pharmaceutical instruments. Testing Sample placed inside the Acrylic Polycarbonate desiccator housing. Desired vacuum level Set in Vacuum controller and It generates a vacuum inside the chamber for a set period. After releasing Vacuum from desiccator we analyze the shape, size & sealing of the testing sample. We perform this test in the methylene blue solution which helps in penetrating the dye & identify the stains with the same color material.
