Cross-contamination potential with dental equipment

The Lancet, 1992
Some types of reused dental equipment, especially handpieces and their attachments for drilling and cleaning teeth, might be responsible for cross-contamination if patient material were to lodge temporarily in difficult-to-disinfect internal mechanisms. This possibility is worrisome with respect to transmission of hepatitis B and human immunodeficiency

Serum zinc concentrations: contamination from laboratory equipment [PDF]

Journal of Parenteral and Enteral Nutrition, 1979
The following experiment was designed because of high serum zinc reported in patients who were receiving total parenteral nutrition (TPN) concentrations. Blood samples were collected, divided into 3 containers: a clean glass control test tube, a vacuum collecting tube with a rubber stopper, and paraffin clot activator.

An investigation of the microbiological contamination of ultrasound equipment

British Journal of Infection Control, 2006
ltrasound equipment comes into direct contact with patients and practitioners during scanning procedures, enabling it to be a potential vehicle for the spread of nosocomial infections. A study was undertaken to determine the extent of contamination on this equipment and therefore the efficacy of the present decontamination guidelines. Five ultrasound

Effect of contamination of pharmaceutical equipment on powder triboelectrification

International Journal of Pharmaceutics, 2000
Triboelectrification of pharmaceutical powders may cause problems during processing and manufacture due to adhesion/cohesion effects. The aim of this work was to investigate the role of adhered particles and moisture as contact surface contaminants on the electrostatic charging of size fractionated lactose, following contact with a surface, i.e ...

Mechanisms of elemental contamination in ion implantation equipment

Proceedings of 11th International Conference on Ion Implantation Technology, 2002
This paper will survey 10 different mechanisms for producing elemental implanted and surface contaminants in implantation tools, and outline the tool design methods for avoiding the contaminants. These considerations also help us to improve the techniques used for surface analysis.
