Choosing the Right Light Fluorinated Fluid for Helium Leak Detection in Optical Instruments

In high-precision inspection fields—especially helium leak detection for optical instruments and precision components—the choice of fluorinated liquid has a direct impact on testing stability and operational efficiency. Through continuous communication with customers and technical teams, Jialede has identified that traditional heavy fluorinated oils often suffer from high viscosity, slow evaporation, and inconsistent batch quality, which negatively affects inspection performance.

According to customer feedback, the Solvay Galden D02 fluorinated oil currently in use shows noticeable batch-to-batch variation. The product feels overly viscous and oily, requiring up to 30 minutes at room temperature to dry naturally, and in some cases even additional baking. This not only extends inspection cycles but also increases operational complexity. Since the liquid is typically used in an open container during testing, evaporation time control becomes a critical consideration.

To address these challenges, Jialede’s technical and procurement teams jointly evaluated alternative solutions and recommended a light fluorinated oil—YBS-3283 fluorinated liquid. Designed specifically for helium leak detection and precision inspection applications, this product features low viscosity, excellent fluidity, and stable batch consistency. During immersion testing, helium leaks can be clearly identified through visible bubble formation, improving both detection accuracy and efficiency.

The customer plans to initially purchase 1 kilogram of the light fluorinated oil for validation, with a 250-gram sample already approved for preliminary testing. The estimated monthly consumption is approximately 150 kilograms. Feedback from the technical department indicates that the evaporation rate is relatively fast, and final confirmation will be made after further evaluation and management approval.
