WHITE PAPERS & CASE STUDIES
The Sizing Of Non-Spherical, Sub-Micron Particles Using Polarization Intensity Differential Scattering (PIDS™)
Nearly all laser-based particle-sizing devices make no allowance for the shape of the materials under test, regardless of the size of the particles. The reason for this lies with the underlying assumptions used for calculating size distributions from the raw data generated during the analysis.
Determination Of Cell Aggregation In Bacteria Cultures For Contact Lens Disinfection Efficacy Testing
The percentage of aggregates in bacteria cultures may be determined by employing the Coulter Principle, also known as Electrical Sensing Zone (ESZ) technique. The ISO International Standard 13319 describes this technique. By Andres Lobeiras, Product Manager, Beckman Coulter, Inc
QC Testing: Quality Control Methods That Make A Difference
By Robert McGregor, Global Marketing and High End Product Manager, Brookfield Engineering Laboratories, Inc.
How do you bring consistency to QC testing? Pharmaceutical products that meet manufacturability criteria and provide high level consumer satisfaction undergo a battery of tests before being distributed to the consumer. Using affordable instrumentation to perform QC tests, which certify that tablets, capsules, elixirs, ointments, etc. have the right physical properties, is essential for today’s successful business.
Viscosity Flow Curve Tells All
Characterizing any material for flow behavior involves testing it over a range of shear rates relevant to how it is processed in manufacturing or how it is used by the consumer. Ointments, for example, are used to coat human body parts like skin, lips, finger/toe nails, hair, eyeballs, etc. The coating action is such that the medicinal mixture, once applied to the surface of the object, spreads as it is rubbed into place. Therefore, a relevant viscosity test would employ shear rates that mimic this type of spreading action.
Sanico Boosts Tablet Inspection To 100%
Pharmaceutical contract manufacturer, Sanico NV, has increased tablet inspection at its Turnhout facility in Belgium to 100%.
Why Filler Feed Back Is Important For Checkweighers
The Filler Feed Back control on a checkweigher is crucial for several applications. It allows you to automatically control the filler to adjust the weight of the product by sending an up/down signal to the filler, slicer, cutter, or dosing device for additional expensive component.
