Solid-State Foaming of Acrylonitrile-Butadiene …

In contrast to the samples without thermal contrast, the foams after the thermal contrast method with fast and slow depressurization rate were different from each other. The mean cell diameter did not change significantly, but the cell nuer density of the sample from fast depressurization was larger than that from slow depressurization, by a factor of 2.7 ( Table 4 ).

CADDI carbon dioxide diagnostic injector | Grifols

Grifols invented a new device for performing angiograms based on using CO 2 as the radiocontrast medium. Carbon dioxide is an ideal alternative to regular contrast agents. It is reliable and provides added safety because it avoids possible compliions such as allergic reactions to iodinated contrast media or renal problems.

Carbon Dioxide Euthanasia for Rats and Mice (BU ASC …

12/6/2020· Carbon dioxide (CO2) overdose causes rapid unconsciousness followed by death. The CO₂ flow rate should displace 10% to 30% of the cage volume per minute. Exposure to CO2 without removing animals from their home cage is a rapid and humane method of euthanasia, because the animals are not stressed by handling or being moved to a new environment.
