Are Your Single-Use Sensor Tests Set Up To Fail?
When it comes to testing methods, experts warn that the same testing methods used on stainless-steel sensors should not be used for single-use sensors. If an attempt is being made to recreate results achieved with a traditional sensor, it’s very possible for those results to appear unfavorable with a single-use sensor.

Merck Assesses Single Use: Does It Make Sense At A Large Scale?In an industry as conservative as the pharmaceutical industry, it is common practice to be adverse to new technologies because they are often viewed as too much of a risk. However, in this effort to play it safe, companies force themselves into a repetitive state of employing technologies that may not be the most efficient or effective. Rather than getting stuck in old habits — or conversely, jumping too quickly into new ones — Merck has put together a group of teams it calls the Technology Encouragement Collaborators, or TEC, to look at new technologies and determine whether or not to implement them.

FDA Approves First Seasonal Influenza Vaccine Manufactured Using Cell Culture Technology
The U.S. Food and Drug Administration announced recently the approval of Flucelvax, the first seasonal influenza vaccine licensed in the United States produced using cultured animal cells, instead of fertilized chicken eggs. Flucelvax is approved to prevent seasonal influenza in people ages 18 years and older.

Proven Long Life Lasers™ In Optical Particle Counters Optical particle counters (OPC) utilize light illumination and extinction to determine the presence, size, number and/or concentration of particles. Particles are typically suspended in a fluid or air, which flow through the volume that is illuminated and viewed by the detection system.

Mammalian Virus Purification Using Ceramic HydroxyapatiteConventional techniques for mammalian virus purification produce variable quality, quantity, and significant loss of particle infectivity. We propose the chromatographic separation of viral particles of diverse sizes and from different families such as dengue, influenza, mouse hepatitis, adenovirus, poliovirus using CHT Ceramic Hydroxyapatite resin.
