Carolina Blood Typing with Eldoncards

Experience trouble-free blood-typing. The antisera are already affixed to the surface of the Eldoncard® (simply moisten to activate) to prevent cross-contamination. So results are quick and reliable. Storage is also easy - Eldoncards are heat sealed in airtight foil envelopes for extended shelf life at room temperature. Carolina Biological is the exclusive North American distributor of Eldoncards in the educational market.
