About Pictured: set of four stainless-steel kidney trays in nested sizes
A kidney tray, also called a kidney dish, is a shallow receptacle used to collect and hold clinical materials, such as instruments, swabs and dressings, during and after treatment. It is one form of dental hollowware.
Why the kidney shape
The curved, kidney-shaped outline lets the tray sit close against the body or another curved surface, so materials can be collected right where they are being removed. It is a shallow, open dish for collecting and holding items. It is not a sealed waste-disposal container or a sterilization container.
Kidney trays and other clinical trays
Kidney trays are one of several receptacle choices, and the differences matter when you select equipment:
- Kidney trays: curved and shallow, for collecting items close to where they are used.
- Rectangular trays: a flat-sided footprint, often used for laying out instruments.
- Lidded receptacles: add a closure for covering the contents.
Instrument cassettes and sterilization containers are different equipment again, made to hold instruments through processing.
Comparing kidney trays
When comparing trays, keep three measurements apart. External length and width describe the footprint, depth describes the profile, and capacity is the usable volume inside. Because a kidney tray is curved, you cannot reliably work out its capacity from its outside dimensions, so compare capacity directly when it matters to you.
The pictured set and other references
The images show a set of four stainless-steel kidney trays, nested in progressively smaller sizes. That set is one configuration. The numbered patterns you can select on this page are separate catalogue references. A pattern number does not tell you the vessel type, dimensions, capacity or order unit, or whether that reference is part of the pictured set. We confirm these details for each reference in your quotation.
