Rychiger recently delivered a compact liquid filling and foil sealing machine for a customer in the diagnostics industry. The customer wanted to fill pre-molded 8 cavity assay kits with 8 different reagents. The liquids to fill included suspensions and beads. The cavities had to be foil sealed with a single foil strip. The required fill accuracy was +- 1%. Fill volume in each cavity was as little as 30 microliters.
The FS 200 mono-block liquid filler and sealer was ideally suited to this application. In two lane design the FS 200 can produce up to 100 assay kits per minute (up to 200 with 4 lanes). The assays are fed from a vibratory feeder onto the filling machines indexing rotary turret. At the filling station piston pumps dose the liquids into each of the 16 cavities simultaneously.
The lid foil arrives at the machine from roll stock. The lid itself is punched in a separate station to avoid particles being shed over the assay kits. A pick and place unit places them onto the assay kits where they are heat sealed. Sealing is at the heart of Rychigers competencies, with over 40 years of experience in the sealing of pre-made containers. The filled and sealed product then exits the machine. At the exit 2 labels are applied to the assay. Of these, one label is in-line printed with variable batch data. Vision control systems verify fill level in the cavities, label presence, barcode legibility and the accuracy of the printed data. Subsequently the assays are automatically loaded into trays and racks ready for down-stream packaging.
Sealing and Filling machines to Medical and Pharmaceutical Standards
Sealing and filling are the heart of Rychigers competencies, with over 40 years of experience in the filling and sealing of pre-made containers. The new FS 200 is designed for medium output applications in the medical and pharmaceutical industry. The compact footprint of less than 3 square meters as well as the GMP design are well suited to the requirements of the medical sector. Rychiger offers full validation services, supplied by their in house validation department.
