At Naturalis they preserve objects in liquid for the conservation of soft tissue. Some jars are over 200 years old. Due to evaporation, the liquid level gradually decreases, requiring continuous monitoring and maintenance. Additionally, many objects are still stored in jars that are not suitable for long-term preservation. They use the MIRA DS to identify whcih liquid is jused for the preservation of an object. Read the interview with David Douw (in Dutch) to find out how they overcome their challenges using the MIRA DS.
