Embedding Ring that we manufacture and supply is known for its excellent finish and durability. It is ideal for holding and identifying tissue sample blocks and it gets fit well in microtome chuck adapters. Our Embedding Ring features an etched writing surface that is marked with an identification number and placed on top of the sample block. Moreover, extra paraffin is poured into the base mold so as to cement the ring onto the tissue block. Our ring firmly holds the tissue sample in the microtome chuck adapter for sectioning and identifying the sample while in storage.
