As cases of COVID-19 began to intensify across the U.S.A. in early spring, a diagnostics manufacturer reached out to ESS Technologies—a provider of complete packaging line design, manufacture, and integration—to build two identical filling systems with automated cap torque for diagnostics vials to be used in manufacturing COVID-19 test kits. The system needed to be fast and capable of filling up to 120 vials per minute. ESS introduces its FC Series Flexible Filler/Capper for vials and small bottles.
