Leak and Seal Strength Tester (Integrated Positive/negative Pressure Method) HY-ZFY-01

(Fully automatic touch screen including printing 500 sets of data storage/query, GMP)
Leak and seal strength tester HY-ZFY-01 adopts the integrated design of positive/negative pressure method, which meets the pressure and vacuum test methods.
It is suitable for the airtightness test of packaging bags, bottle caps, vials/powder injection bottles, ampoules and other packaging products.
It is an ideal testing instrument for industries such as food, plastic flexible packaging, wet wipes, pharmaceuticals, and daily chemicals.



Detail Introduction

Technical features

1. The device is equipped with a 5-inch high-definition touch screen, controlled by a microcomputer, and equipped with a silent micro-printer;
2. Positive pressure/negative pressure test "one-button" switch, support setting multi-stage pressure test;
3. Intelligent pressurization, pressure maintenance, pressure supplementation, timing, and pressure relief test process are automatically completed;
4. User hierarchical permission setting, meeting GMP requirements, test record auditing, tracking functions;
5. Using a circular structure container, the air pressure is evenly distributed, and the pressure bearing capacity is better;
6. Pure copper safety valve to prevent overpressure (the pressure will be automatically relieved if it exceeds the set pressure) and it is safer to use;


Test Principle

Microbial intrusion test, also known as microbial challenge, is a relatively common seal integrity test method, usually performed simultaneously with simulated filling. Carry out simulated filling of the culture medium according to the simulated filling verification scheme, and then carry out the plugging and capping, and the visual inspection is qualified. After the sterilization of the verified sterilization cabinet, the sealing surface of the container is immersed in the high-concentration bacterial solution. Make the culture medium in the sample container fully contact the inner surface of the seal. The neck of the sample and the outer surface of the seal should be completely soaked in the bacterial suspension. After soaking for a certain period of time, take it out. After regular culture, check whether there is microbial invasion to ensure that the container is sealed. system integrity.
At the same time, a positive control test is required to confirm the growth-promoting ability of the medium. Challenging conditions of vacuum or overpressure are often used in testing.
The instrument conforms to many national and international standards: GB/T 10440, GB/T 18454, GB/T 19741, GB/T 8368, YY/T0681, YY 0285, ASTM F1140, etc.
