Non-Destructive Leak Detector C690H Delivers High-Accuracy, High-Throughput CCI Testing for Pharma Packaging

Labthink C690H Non-Destructive Leak Detector uses a vacuum-based testing method (and also a positive pressure method) to find tiny leaks in different kinds of containers. It's built according to international standards like ASTM F2338 and is particularly useful for checking various packaging in industries like food, pharmaceuticals, daily chemicals, and electronics, such as vials, ampoule, cartridge bottles, infusion bottles and prefilled syringes.


How it works

It works by placing the sample in a sealed chamber, creating a vacuum, and then using sensors and a fluid dynamics model to calculate the leak rate and the size of the leak based on how fast the pressure drops.

It can operate in two modes:

  • Vacuum mode: It creates a negative pressure (vacuum) around the sample and measures how quickly the pressure inside the sample drops. This works well for most packaging types because the vacuum helps to "pull" out any leaks, making them easier to detect.
  • Positive pressure mode: It applies positive pressure (pushes air in) to the sample. This is particularly useful for packaging with special structures or for products like powders, where tiny holes might get blocked in a vacuum. Applying positive pressure helps to "flush out" and detect these blocked leaks.




Key features

Precision

The machine can detect very small leaks, down to 3～8 μm (which meets the USP <1207> standard for reference hole sizes). It's very precise, with a resolution of 0.1 micrometers and consistent results (repeatability error of only ±1 micrometer).

Efficiency

Labthink C690H has an automatic sample feeder that can test many samples continuously (from 20 to 120).

Micro-flow control with advanced algorithms to simulate different leak sizes without needing manual adjustments.

Compliance

Data traceability to the U.S. National Institute of Standards and Technology (NIST) and compliance with international standards like ASTM F2338 and USP <1207>. It also meets strict requirements for the pharmaceutical industry, like GMP and 21 CFR Part 11 for electronic signatures.

In short, Labthink C690H is an ideal tool for ensuring product sealing integrity. It combines vacuum decay and positive pressure testing to accurately detect tiny leaks, offers automated sample handling, and provides smart analysis, all while complying with global industry standards, especially in demanding fields like pharmaceuticals and electronics.

Case Study: Oxygen Barrier Properties of Recycled PET Bottles

Image
Recycling plastic bottles is vital for environmental protection, but it can affect their oxygen barrier properties, making them less suitable for oxygen-sensitive products. Our case study on PET bottles with varying amounts of recycled material found that increasing the recycled content from 25% to 50% only slightly reduced their oxygen barrier. This suggests that using more recycled material does not significantly compromise the bottles' performance. The Problem The growing trend of recycling waste plastic bottles requires an understanding of how reclaimed materials affect a product's performance. For PET bottles, a crucial metric is their ability to act as an oxygen barrier. High oxygen permeability can compromise the quality of packaged goods, limiting the use of recycled materials in food and beverage containers. This study aims to quantify that effect by testing bottles with varying percentages of recycled content. The Test Two types of PET bottle samples were tested...

Why Water Vapor Permeability is Critical for OLED Displays and How to Measure it

Image
OLED is extremely sensitivity to water vapor, even microscopic amounts of moisture can lead to rapid degradation, causing unsightly dark spots, short circuits, and significantly shortening the display's lifespan. This is why the OLED Display Water Vapor Transmission Rate Test is so important. The impact of WVTR testing extends far beyond mere measurement; it directly influences the quality, longevity, and market viability of OLED products. Ensuring OLED Device Lifespan and Performance: OLED components are extremely vulnerable to moisture. Water vapor ingress causes metal electrodes to oxidize and organic layers to degrade, leading to critical issues like dark spots and short circuits.To achieve an OLED device lifespan of at least 10,000 hours, the industry recognizes a critical WVTR target of 1 x 10 ⁻⁶ g/(m ²· day). This tester precisely measures and verifies that encapsulation materials meet this stringent requirement. Optimizing Materials and Processes: By testing the ...

Container Closure Integrity (CCI) testing - methods and instruments

Image
Container Closure Integrity (CCI) testing is performed within the pharmaceutical, biotech, and food and beverage industries, primarily to ensure product sterility and prevent contamination, maintain product quality and stability, identify packaging defects, and meet regulatory requirements. Regulatory bodies like the FDA (in the United States) and similar agencies worldwide have stringent requirements for container closure systems, particularly for sterile and pharmaceutical products. These regulations mandate that manufacturers demonstrate the integrity of their packaging to ensure product safety and efficacy. There are various instruments used for Container Closure Integrity (CCI) testing, employing different methods to detect leaks. Such as vacuum decay testers, pressure decay testers, High Voltage Leak Detection (HVLD) instruments, and mass extraction leak detectors, these instruments employ deterministic methods which provide quantitative, objective results. Probabilistic methods ...
