Input: Question: Does porcine liver vascular bed in Biodur E20 corrosion cast?
Answer: Only Biodur E20®️Plus appeared to be suitable for high-volume vascular corrosion casting due to its optimal permeability, sufficient processing time and minimum fragility. Biodur E20®️ Plus is slightly elastic, radio-opaque and alcohol-resistant. These properties make this acrylic resin suitable for not only vascular research but also teaching purposes.
Output:
yes
