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. Plan to use specimens within one year of purchase to ensure the best tissue quality. Specimen discoloration and dryness over time is normal and does not indicate decay.
Store your specimens at normal room temperature—refrigeration is not required. Storage in attics or garages at high temperatures will damage the specimens. Once opened, specimens can be resealed in a zip-lock bag to prevent them from drying out for later use.
Shipping Note: This item contains preserved specimens and only ships to a street address in the 50 US states.
