Leak Test Apparatus

A Vacuum 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 placed tablets sachet into the desiccator filled with Methylene blue and then vacuumed 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 the desiccator from the vacuum pump.

Digital timer plays an important role in the testing of tablets in Vacuum leak tester which explains the capacity to handle the 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 at the best prices in INDIA.

Working of a Vacuum Leak Tester :

The Vacuum leak test apparatus makes it very easy to operate the pharmaceutical instruments. Testing Sample was placed inside the Acrylic Polycarbonate desiccator housing. The desired vacuum level is Set in the Vacuum controller and It generates a vacuum inside the chamber for a set period. After releasing the Vacuum from the 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.

• Vacuum leak testing machine has two part : one part has complete controlling unit with vacuum pump where second part is transparent desiccators connected with the main unit by vacuum pipe.
• Machine has a many parameters that should be entered before performing the leakage test.
• Vacuum level must be within the range of 200 mm hg to 600  mm hg.
• Machine performs self vacuum testing for 30 second in the beginning.
• Vacuum pump generates required vacuum for the vacuum chamber when sample is dipped into the colored water.
• Vacuum generated Internal and External pressure difference is observed in the gas leakage condition that determine the sealing quality of water dipped sample.
• Pressure difference is directly related to the pouches sealing performance & shape of the samples pouches recovered after the release of vacuum.

Leak Testers are specially designed for Food & Pharmaceutical packaging 

There are three types of packaging in the food industry. One is Flexible packaging Others are Held Hard package & Hard package. Packaging is always performed based on the material’s shelf life and safety.

Flexible package: Seed bags, Tetra packs, puffed food packaging, rice bags, chips packets, Cake packages, Milk Powder packing, Cheese packages, Coffee bags & Wet tissue packs means it can perform testing of different types of food packages with any shape or size.

Half-hard package: Retort pouches, Tomato Sauce packs, Jelly Packs, Yogurt Package, Salver packages, bulky chips packets, Medicines, Tablets, Eye drops, Oil sachets, and Shampoo sachets so it can test half-hard type packaging material in the food & Pharma industry.

Hard package: Injectables, Cough Syrups, Medicines stored in colored bottles, milk powder steel can, beverage bottle, oil drum, tin, biscuit keg, coffee bottle & zip-top can. It can check and perform testing of Hard packaging material stored in Glass bottles & steel cans.

Leak Tester Calibrator / Vacuum Calibrator / Vacuum digital pressure calibrator – Model – PV 101

Yatherm PV 101 is precision digital vacuum calibrator device is specially designed to validate and cross check the vacuum generated in vacuum leak test apparatus. A further advantage is that digital pressure gauge can also be used as a pressure reference. This makes testing very easy with adjustments and calibration(Auto zero prior to all test) for other measuring instruments on site. It has highly efficient measuring sensor that has an accuracy of 0.05% FS. This device is very user friendly finishes calibration job with 3 tactile switches. Microprocessor of the device automatically corrects zero point before every test and its linearity ensures the accuracy of the Calibrator.

Features

• High Accuracy
