Success Story: High-Throughput Solvent Extraction for Efficient Rubber Analysis

In the tire and rubber industry, rigorous quality control and testing are needed to guarantee high static and dynamic performance. One of the parameters that companies must monitor is the acetone extract, a standard requirement for determining the content of resins, oils, and other soluble substances within the rubber matrix. 

Rubber Conversion was looking for a solution that could deliver accurate and reliable acetone extract measurements, but they faced a significant bottleneck with the conventional methodology. The traditional Soxhlet extraction method, while effective, is a time-consuming process that typically requires 16 hours to complete a single run. This lengthy duration is largely due to the use of cold solvents, which are less efficient at dissolving analytes compared to hot solvents, and the limited throughput of traditional glassware which typically accommodates fewer samples.

Furthermore, the traditional approach often involves prolonged exposure to solvents, posing potential health risks to operators. Consequently, Rubber Conversion sought to improve on these limitations to align with their efficient, sustainable circular model.

The adoption of the Velp SER 158 has brought significant and measurable advantages to Rubber Conversion’s operations:

• Remarkable time savings: analysis duration has been cut from 16 hours to just 7, dramatically accelerating the workflow.
• Improved cost efficiency: faster processing means lower operational costs and increased productivity.
• Maximum operator safety: the SER 158 is fully automated—from solvent dosing to the automatic lifting of cups at the end of the process—minimizing human error and ensuring a safe working environment.
• Consistent and accurate results: the solution delivers reliable outcomes that comply with strict industry standards.
• Exceptional solvent recovery: up to 90% of solvent is recovered through the integrated tank, reducing waste and saving on material costs.
• Smart connectivity: cloud-based features allow users to monitor and manage multiple extractions remotely, while also accessing advanced application and service support.
