Understanding aseptic filling technology

Aseptic fillers. The main target of an aseptic filling line is to reach and to maintain the sterility of container, environment and product through each step of the bottling process. In this way, the organoleptic features of the product are kept for a pre-determined shelf life at room temperature.

Aseptic Manufacturing and Sterile Fill-Finish for Complex ...

Aseptic Manufacturing and Sterile Fill-Finish: A process in which the drug product, container, and closure are first subjected to sterilization methods separately, as appropriate, and then brought together (aseptic manufacturing). Because there is no process to sterilize the product in its final container, it is critical that containers be ...

Retrieval analysis of alumina ceramic-on-ceramic bearing couples

The explanted joints tested operated in a mixed/boundary lubrication regime with a decreasing friction factor observed with increasing Sommerfeld number. Diametral clearances This was performed on the 5 joints that underwent friction analysis, with a view to explaining the performance, and the results are illustrated in Table 4 .

The effect of lubrication on the friction and wear of Biolox ...

Thus, the current flat worn surface morphology in the mixed-lubrication regime results from the mechanical aspects of wear arising from direct asperity-on-asperity contact, which is consistent with the predicted lubrication conditions from the Stribeck curve.

Aseptic Technique and the Transfer of Microorganisms (Theory ...

Aseptic technique is also essential for isolation of a single species of microorganism from a mixed culture to obtain a pure culture. Furthermore, proper aseptic technique prevents microbes used in the laboratory from accidentally being released into the environment and/ or infecting people working in the laboratory.

Medication Preparation Questions | Injection Safety | CDC

From an infection control perspective, the safest practice is to prepare an injection as close as possible to the time of administration to the patient. This is to prevent compromised sterility (i.e., microbial contamination or proliferation) or compromised physical and chemical stability (e.g., loss of potency, adsorption to the container) of ...

Lubrication and friction prediction in metal-on-metal hip ...

film thickness show that metal-on-metal hip joint implants operate in a mixed lubrication regime. Significant efforts in reducing asperity contact and improving fluid film protection have been made to reduce friction and wear (Scholes and Unsworth 2000). Mixed lubrication generally includes both fluid film lubricated and boundary asperity

(PDF) Comparison of friction and lubrication of different hip ...

Mixed lubrication was found to occur in the metal-on-metal (CoCrMo/CoCrMo) joints with all lubricants at a viscosity within the physiological range. This was also the case for the metal-on-plastic ...

Ring-Shaped Surface Microstructures for Improved Lubrication ...

The microstructuring of surfaces is a highly researched field that is aimed at enhancing the tribological behavior of sliding surfaces such as artificial joints, which are subject to wear. Lubrication of the joint interface plays a key role in the wear process, although the mechanisms of lubrication are quite complex. In order to improve the lubrication, the surfaces of the articulating ...
