Sealing sample tubes correctly is a critical step in any laboratory workflow. Proper capping protects sample integrity, prevents contamination, and ensures accurate traceability. Over time, sample tube capping has evolved from fully manual methods to advanced automated systems that improve both efficiency and reliability, particularly in high-throughput laboratories.
In the past, laboratory staff relied entirely on manual capping using screw caps or push-on lids. While manageable for small sample volumes, this approach was time-consuming, labor-intensive, and prone to inconsistencies. Misaligned or improperly sealed caps could cause leaks, evaporation, or contamination, putting valuable samples at risk.
Automated capping systems address these challenges by providing fast, reproducible, and standardized sealing for large numbers of samples. AFYS3G’s advanced cappers, such as the Sigma96 and Sigma STR, are designed to integrate seamlessly into laboratory workflows, reducing human error, saving time, and maintaining sample integrity. The Sigma96 is optimized for high-throughput applications, quickly capping entire racks of sample tubes with uniform precision. The Sigma STR offers flexibility for various tube sizes and formats, allowing laboratories to manage diverse sample collections without compromising speed or reliability – all while minimizing repetitive manual capping tasks.


By adopting automated cappers, laboratories not only protect valuable samples but also free up personnel from repetitive manual tasks, allowing staff to focus on higher-value activities such as analysis, quality control, or research. This combination of efficiency, safety, and productivity makes automated capping an essential component of modern laboratory operations.
AFYS3G’s Sigma96 and Sigma STR systems demonstrate how automation transforms routine manual capping into a reliable, high-performance process, ensuring consistency and accuracy.
