Guided Wave Radar at Genentech: A Novel Technique for Non-invasive Volume Measurement in Disposable Bioprocess Bags
in a simple tray, but larger bags are typically housed in a bioprocess container--a plastic or stainless steel bin that supports the filled bag. Bioprocess containers greater than 500L are often stationary while smaller bins are typically portable. New sensor technologies for pH, DO, conductivity

Trash in, cash out
Machine vision spots treasure in trash and makes possible single-stream recycling. Recycling was a somewhat onerous process when first introduced in North America and Europe. Participants presorted glass, paper, plastic, and metal into separate, color-coded containers and placed them curbside

Chutes and Leaders
(RFID) and barcode technology to track all materials and products, keep resources evenly distributed and prevent production logjams. The barcodes are found on bins used during the manufacturing process and the smaller plastic totes used for shuttling finished product to the packaging plant

Weighing and Dispensing: Do it Right
MovementNon-hazardous solid waste (i.e., paper, cartons, plastic, etc.) generated in the weighing area is collected in plastic bins and transferred via a dumpster to a waste compactor. All contaminated solid waste should be disposed of in accordance with hazardous material regulations.Facility Design LayoutThe

Weighing and Dispensing: Do it Right
and by the ergonomic capabilities of the operators. Platform floor scales that can be accessed with a hand truck are used for weighing 50- to 100-kg quantities into plastic and stainless steel drums and tubs. Platform scales can be used for pails or plastic bags of materials ranging from 10 to 50 kg. One

truck are used for weighing 50- to 100-kg quantities into plastic and stainless steel drums and tubs. Platform scales can be used for pails or plastic bags of materials ranging from 10 to 50 kg. One or two bench scales will also typically be present, the first for 1- to 10-kg quantities and the second

Low-pressure molding offers stiff competition
(such as nitrogen N2) into the thermoplastic resin melt. The gas and plastic dynamically mix under high backpressure inside the extruder barrel of the injection-molding machine (IMM). The gas dissolves forming a homogenous mixture of single-phase solution and microscopic gas bubbles. The resin/gas mixture

Good vents make good housings
and shapes, and in molded plastic and metal housings. Gore Protective Vents can be snap-fit, threaded, bolted, adhesive bonded, or heat/ultrasonic welded into place. One-micron latex spheres get caught in ePTFE membrane, the same material used in Gore vents. Watertight enclosures are no guarantee
