Plain preserved specimens. Kidney of an adult sheep.
Due to limited availability of sheep kidneys, we may occasionally substitute pig kidneys. Pig kidneys are slightly larger, just as easy to dissect, and have identical external and internal features. Kidneys come with slits in them due to a mandatory inspection process.
Note: Specimens are initially preserved with a formaldehyde solution, the best animal tissue fixative. The formaldehyde is then displaced first with water and finally with a glycol solution to produce a moist, low-fume specimen which will not decay over time.
HST Specimen Guarantee
In sealed, original packaging, our preserved specimens are guaranteed to remain fully preserved and free of decay for six months from the date of purchase.
