SPT-403

Function

Non destructive testing of leakage rate and leakage aperture of flexible and rigid packaging components.

Compliant with standards

ASTM F2338, USP1207 Recommended Methods, Technical Guidelines for Sealing Study of Chemical Injection Packaging Systems.

Working principle

Integration of three methods: vacuum attenuation method, water tracing method (optional), oxygen tracing method (optional).

50. Vacuum attenuation method: Standard configuration.

1. Sample installation: Place the packaging and its fixtures in the test chamber, cover the test chamber lid and seal it;
2. Leak detection: After evacuating the storage space between the packaging and the testing chamber or fixture for a period of time, close the valve, monitor the pressure changes in the storage space, compare with the standard sample, and evaluate whether there is a large leak;
3. Small leak detection: When there is no major leak in the packaging, the instrument automatically evacuates the storage space again; Close the valve, monitor the pressure changes of the storage space with sensors over time, compare with the standard sample, calculate the leakage rate and leakage aperture of the packaging, and evaluate the integrity of the packaging;

50. Water tracinglaw: Optional.

1. Sample installation: Place the packaging (containing water) into the testing chamber, cover it with the testing chamber lid and seal it;
2. Pollution flushing: Dry nitrogen gas (carrier gas) flows at a fixed flow rate on the outside of the packaging, and releases the water vapor in the packaging space and the water vapor leaked from the packaging to the ambient atmosphere;
3. Leakage measurement: Water vapor inside the packaging leaks from the packaging to the carrier gas outside the packaging; The carrier gas carries leaked water molecules to the trace water sensor; The sensor electrolyzes all the moisture in the carrier gas, measures the absolute water content, compares it with the standard positive sample, calculates the leakage rate and leakage aperture of the packaging, and evaluates the integrity of the packaging.

50. Oxygen tracerlaw: Optional.

1. Sample installation: Place the packaging (containing oxygen) into the test chamber, cover the test chamber lid and seal it;
2. Pollution flushing: Dry nitrogen gas (carrier gas) flows at a fixed flow rate on the outside of the packaging, and discharges the oxygen in the packaging space and the oxygen leaked from the packaging to the ambient atmosphere;
3. Leakage measurement: Oxygen inside the packaging leaks from the packaging to the carrier gas outside the packaging; The carrier gas carries leaked oxygen molecules to the trace oxygen sensor; Measure the oxygen content, compare it with the standard positive sample, calculate the leakage rate and pore size of the packaging, and evaluate the integrity of the packaging.

FEATURES

• Basic method: Vacuum decay method.
• Expansion methods: Water tracing method, oxygen tracing method, optional or upgraded.
• Non destructive testing: No need to damage the sample to detect the leakage rate and leakage aperture of flexible and rigid packaging.
• Extensive testing: Evaluate packaging for major leaks, medium leaks, minor leaks, and minor leaks. Can evaluate packaging containing gas, oxygen, and water vapor media. Customizable packaging to accommodate testing fixtures (vacuum attenuation method); Tracer method does not require fixtures.
• Test modes: vacuum attenuation method, water tracing method, oxygen tracing method.
• Calibration modes: positive control, flow calibration, negative control.
• Positive control samples: 5 pore sizes, 2um, 5um, 10um, 20um, 50um, with an error of less than 5%.
• Temperature control method: Stainless steel metal test chamber with constant temperature, semiconductor cold and hot bidirectional precision control of the temperature in the test chamber.
• Anti leakage technology: equipped with anti leakage technology (water tracing method, oxygen tracing method) for the joint surface between the cabin cover and the test cabin body.
• Intelligent automatic: Select testing mode, one click start, fully automatic testing, can automatically determine whether it is qualified or unqualified according to preset limits.
• Monitoring and measurement: Real time monitoring and recording throughout the entire process. Graphic representation, full process and all element recording, with no loss of power-off data.
• Data security: The optional "GMP Computerized System" software module has functions such as user and permission management, audit tracking, etc.
• Fault diagnosis: Power on self-test to avoid continuing testing in a faulty state;
• Working environment: Room temperature, no need for constant temperature and humidity environment (reducing usage costs).
