CORALVILLE, Iowa--(BUSINESS WIRE)--Vivakor, Inc. (OTCBB: VIVK) today announced the successful testing results of its new self-sealing caps for its VivaThermic vials. The unique self-sealing cap was designed to provide a superior seal, preventing leakage and cross-contamination, without utilization of o-rings or similar seals that are commonly used in currently available products and which may be compromised at cryogenic temperatures, leading to leakage or cross-contamination. Data from these recent tests show that the new self-sealing cap design can reliably withstand positive and negative pressures of greater than 645 torr for extended periods of time.
