  • Control of Welding Fume Particulates using Cleanable Filter Media as it relates to Hexavalent Chromium
    Herein, a Sentry Air Systems product study of hexavalent chromium particles, [Cr(VI)], is reported. Due to the popularity of extended life cleanable filter media and health concerns regarding hexavalent chromium exposure in the work place, Sentry Air Systems conducted a study of the efficacy
  • Shot Particle Shapes (.pdf)
    The ideal shape for a shot particle is a sphere, but real shot particles are not perfect spheres. The most commonly employed media are cast steel and iron shot, cut steel and iron shot, cut steel wire shot, glass beads and ceramic beads. These media are manufactured either by spheroidising solid
  • Gauge Configurations for High Temperature Applications (.pdf)
    140° F is the maximum recommended ambient media temperature for NOSHOK pressure gauges with brass wetted parts, and 212° F for gauges with stainless steel wetted parts. For applications in which media reaches temperatures above 212° F, NOSHOK offers several accessories designed to prevent damage

    sizes. The peel-apart pouches in paper or film media can be sterilized. The RCN 160 wraps flat disposables, such as surgical gloves, gauze, wound dressings, or catheters, in pouches up to 160 mm wide. The RCN 270 comes in stainless steel and can create pouches up to 270 mm wide. The machines
  • When to go Linear
    . Optical encoders use a light scanning principle where two scaled gratings of equal graduations move relative to each other. A reflective glass or steel-tape media has nonreflective stripes forming one grating. An index grating of opaque strips on a transparent material moves along the reflective media
  • Throwing it All Away
    and vertically into various niches through the process chain. Plastic bags replaced steel tanks for media and buffer storage, then morphed into mixing containers and bioreactors. Plastic tubing, valves and connectors encroached on stainless steel pipes and manifolds. Membrane filters appeared housed
  • MICRO: Products
    features include backside rinse and topside edge-bead removal. The station has a compact 19 32-in. footprint and allows for self-contained process chemical and waste storage. Key Speedy 316L ISO components are used in high-temperature and corrosive applications in a wide range of media
  • Standard Specification for Tracer Materials
    The tracer in a steam tracing system must be as flexible as possible for ease of installation and conformance to the shape and layout of the process pipes and equipment being heated and must act as a leakproof carrier of the heating media. Whenever possible it is recommended that semi-rigid tubing
  • Hydraulic Tube Fittings Deliver Leak-Free Performance and Long Life
    is driven by the following fluid system parameters: size, temperature, application, media, and pressure, often referred to as the acronym STAMP. Consider the tube outside diameter (OD) and wall thickness for all tube fittings. Most types are limited due to tube wall thickness. Flare-type fittings

  • Guided Wave Radar at Genentech: A Novel Technique for Non-invasive Volume Measurement in Disposable Bioprocess Bags
    By Bryan Bean, Tim Matthews, Neria Daniel, Steve Ward, Brad Wolk, Genentech, Inc. Disposable bioprocess bags are increasingly being used in biopharmaceutical operations for buffer storage, buffer and media prep, bioreactors, product pooling and storage of bulk drug substance. Disposables offer
  • Water Jets Cut Machining Time, Cost
    water-jet cutting with CNC X-Y-Z programming instead. A stream of water with adjustable flow rate, water pressure, and diameter cuts into parts. Plain water cuts softer materials like reinforced plastics and composites. Abrasive media speed cutting or assist in cutting harder materials. Water-jet cutting

    and plastics. The ceramic powder particles are less than 1 um in size. These powder particles are blended with a plastic media that acts as a binder system. The initial mixture that goes into the injection molding equipment is roughly two-thirds ceramic and one-third plastic. The plastic acts as a carrier
