Polymer Sample Extraction Protocol

Extractions of polymer samples were obtained according to ISO standard 10993–12. The extraction was performed in cleaned borosilicate glass vials and water (LC-MS Ultra Chromasolv, Sigma Aldrich, for the chemical analysis and MilliQ water for the cytotoxicity analysis) was used as the extraction medium. The ratio of the surface area of the OSTE+, OSTE+H₂O, polyimide or HDPE samples and the water was 3 cm²/ml. The samples were washed in MilliQ water before extraction. The vials were gently shaken at 37 °C for 72 h. When the extraction solution was used in cytotoxicity tests, the polymer samples were first sterilized using an autoclave at 121 °C and the extractions were performed with sterile water.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
