So-called “featherweight” in-line E-beam sterilizers have been developed by a manufacturer of accelerators to satisfy OEM demand for compact treatment systems for use on high-speed filling lines.
Linac Technologies (Orsay, France) recently installed four such systems to treat syringe tubs at the facility of a multinational pharmaceuticals company.
“Each unit contains three low-energy accelerators in a triangular configuration within a lead housing connected to the filling isolator,” explains Fiona Malcolm, executive assistant for marketing and sales. “The three-beam design ensures that the entire surface of the tub is exposed to a 25-kGy radiation dose,” she adds. The conveyor system guarantees output and proper exposure time, while the isolator interface provides differential pressure and clean air inside the tunnel. The tunnel is flushed with H2O2 prior to production for decontamination purposes. The accelerator and conveyor system are connected to the filling-line computer and constitute a continuous sterile transfer system with a throughput of six tubs per minute, or 36,000 syringes per hour.
The company also supplies 3- to 5-kW machines with a maximum size of 4 ¥ 3 ¥ 2.8 m, including protective shielding. These units are compatible with the output of many manufacturing operations while requiring minimal floor space. Larger 10- to 20-kW units are also available.
Products routinely processed by E-beam equipment designed by Linac Technologies include IV devices, catheters and probes, surgical instruments, implantables, dressings and bandages, and gowns, drapes, and gloves. Accelerators have been installed in medical manufacturing facilities worldwide.
