Equipment, Devices, and Reagents

UPDATE: Equipment, Devices, and Reagents, we will no longer require the inclusion of the location of the manufacturer. This is so easy to look up online, should anyone desire more specific details, that we believe it is not necessary to continue to require this. This change was made October 4, 2011.

As with drugs and isotopes, nonproprietary names or descriptive phrasing is preferred to proprietary names for devices, equipment, and reagents, particularly in the context of general statements and interchangeable items (eg, urinary catheters, intravenous catheters, pumps). However, if several brands of the same product are being compared or if the use of proprietary names is necessary for clarity or to replicate the study, proprietary names should be given at first mention along with the nonproprietary name. In such cases information regarding the manufacturer or supplier and location also is important, and authors should include this information in parentheses after the name or description. Authors should provide this information for any reagents, antibodies, enzymes, or probes used in investigations.

The following are examples where specific information is required:

The positron emission tomography (PET) unit (4096 Plus; General Electric Systems, Milwaukee, Wisconsin) comprised 8 detector rings positioned in a cylindrical array. Image processing and reconstruction were performed with a VAX 4000–300 computer system and a VAX 3100 workstation (Digital Equipment, Marlboro, Massachusetts).

All magnetic resonance angiography examinations were performed with a 1.5-T whole-body imager (General Electric Medical Systems, Milwaukee, Wisconsin).

The following are examples of general references:

Some hearing loss may result from use of a portable radio or cassette player equipped with headphones (Walkman-style) played at high decibel levels.

Currently, treatment by Nd:YAG laser is the accepted method to surgically open the opacified posterior capsule.

As with drugs and isotopes, proprietary names should be capitalized; the registered trademark symbol is not used.

If a device is described as “modified,” the modification should be explained or an explanatory reference cited. If equipment or apparatus is provided free of charge by the manufacturer, this fact should be included in the acknowledgment (see 2.10.8, Manuscript Preparation, Acknowledgment Section, Funding/Support; 5.2.1, Ethical and Legal Considerations, Acknowledgments, Acknowledging Support, Assistance, and Contributions of Those Who Are Not Authors; and 5.5.2, Ethical and Legal Considerations, Conflicts of Interest, Reporting Funding and Other Support).
