Spin Column Case Study

The client required an automated assembly system to produce a custom membrane inside a vial used for DNA/RNA purification. This process involved handling ultra-thin layers of glass microfiber filter paper—a delicate material that needed precision in de-reeling, punching, and assembling to avoid damage or compromising the product’s integrity. An additional challenge was the need for cap closure and capped vial feeding, adding complexity to the fully automated system.

Lanco leveraged its deep industry experience, including prior projects with similar materials, to develop a robust solution. The design emphasized specialized mechanisms for pallet conveyance in handling the thin filter paper, and vision inspection to ensure accuracy throughout the assembly. Drawing on prior experience with both tethered and non-tethered vials, Lanco also integrated a feeder capable of accommodating the tethered cap design seamlessly.

The automated solution delivered impressive efficiency, with good parts being accumulated and offloaded through automatic bagging into zippered bags at a rate of 0.6 seconds per part, or approximately 6,000 parts per hour. The project demonstrated Lanco’s ability to tailor complex automation solutions to meet the unique needs of clients in the life sciences industry.
