PharmTech's monthly newsletter, Equipment & Processing Report, reviews the Editor's Picks for the May 2009 edition from Continental Disc and Filimatic.
Rupture disc withstands severe conditions
Continental Disc (Liberty, MO) has added the MP unit to its SanitRX series of rupture discs. The product was designed for applications during which conditions frequently change between positive pressure and vacuum. The company moved the disc’s score line from the contact side to the downstream side so that it is subject to less stress when pressure changes. The new position also improves the disc’s cleanability. The disc can be cleaned or steamed in place.
The disc complies with the American Society for Mechanical Engineers’s bioprocessing equipment criteria for process-side surface finish and fully traceable metal and elastomer materials. The component also is free of polishing compounds, release agents, and animal derivatives. The disc’s flow-resistance values are 1.13 for gas and 1.60 for liquid. The disc is appropriate for pressure-vessel applications such as autoclaves, fermenters, and heat exchangers.
Adaptive filling machine
Filamatic’s (Baltimore, MD) AdaptaFil semiautomatic filling machine now offers interchangeable peristaltic, gear, lobe, and piston pumps. Pump changeover does not require tools and enables users to adapt the device to run new products. Changeover also reduces operators’ need to learn how to use new equipment, says Jack Chopper, chief electrical engineer for Filamatic.
The unit can operate at production scale and can be incorporated into an automatic filling line. The filler’s human–machine interface allows operators to save and retrieve recipes by name and number, copy recipes to other machines, and change fill setups easily. The machine’s software system provides control over fill speeds and delay time between fill segments. Users can calibrate a fill with the push of a button.
