Quality you can trust
Both RDO and RDO Gold are unsurpassed decalicfiers that can be tailored to suit your specific lab routine.
RDO was developed with the basic premise of making your work routine quicker and easier. RDO is presently being used by thousands of technicians world-wide and is the decalcifier of choice when superior staining qualities are desired in a minimum amount of time.
Gentle on specimens
RDO Rapid Decalcifier is a major improvement to histological processing procedures. Compared with other commercially available decalcifiers, RDO gently decalcifies specimens in a fraction of the time.
Both RDO and RDO Gold may be diluted with tap water to permit multipurpose use. Dilution with tap water is recommended for mildly calcified specimens such as bone marrow biopsies (core). In either case, the standard procedure should be to check the specimen periodically to determine the endpoint of decalcification.
