Vacuum decay methods offer a non-destructive alternative. The Vacutainer is initially filled with a known pressure of air or an inert gas. Sensitive pressure sensors then continuously monitor the pressure within the tube. Any significant drop in pressure over time indicates a leak.

This method is highly sensitive, capable of detecting even minor leaks that might otherwise go unnoticed. It can be automated for high-volume production lines, improving efficiency and providing quantitative data on leak rates. This data allows for precise quality control and the identification of potential production issues.

Labthink C690H Nondestructive Package Leak Detector is based on the testing principle of the vacuum decay method, designed and manufactured according to ASTM F2338 and other standards. It is professionally suitable for batch sealing leak detection of vials, and trace leakage detection of ampoule, cartridge bottles, infusion bottles, prefilled syringes and other pharmaceutical packaging.

Vacuum decay testing is a valuable tool for ensuring the highest quality standards in Vacutainer production. By integrating this method into manufacturing processes, manufacturers can enhance efficiency and ensure the safety and reliability of these crucial medical devices.

Testing Oxygen Permeability in Contact Lenses

For comfortable and healthy contact lens wear, oxygen must reach the cornea. Insufficient oxygen can cause discomfort, dryness, and potentially serious eye problems. This is why oxygen permeability testing is so important. It measures how much oxygen can pass through a contact lens material, ensuring adequate oxygen supply to the eye.

Various methods exist to measure oxygen permeability, each designed to accurately quantify a lens's ability to "breathe." This measurement is expressed as Dk/t, where D (Diffusivity) represents the rate at which oxygen moves through the material, and k (Solubility) indicates how much oxygen can dissolve within the material, t refers to the thickness of the lens. A higher Dk/t value signifies greater oxygen flow to the cornea, minimizing the risk of hypoxia (oxygen deficiency).

ISO 18369 provides a general framework and defines terms related to contact lenses, including oxygen permeability. It specifically outlines the procedures for both polarographic and coulometric methods. ISO 9913 focuses specifically on the coulometric method for measuring oxygen permeability. It provides detailed instructions on the equipment, calibration, and testing procedures.

Labthink C230H Oxygen Transmission Rate Test System is designed and manufactured based on the coulometric sensor method. This instrument can be used to measure the oxygen transmission rate of materials with high and medium barrier properties with high accuracy and high efficiency.

This testing is crucial for both manufacturers and wearers. It allows manufacturers to develop and refine lens materials that prioritize eye health. For wearers, it ensures they choose lenses that provide sufficient oxygen, promoting comfort and reducing the risk of complications.
