You should saturate the builder gel with acetone and let it sit for 10-15 minutes before gently scraping off the product. Once all of the builder gel has been removed, you can use a cotton swab dipped in alcohol to clean off any residue that may be left behind.
Webbreactive (2). Reversible gels refer to those that have the capacity to make, break, and modify the bonds responsible for holding the network together. Gels that do not have this capability because they are held together by covalent bonds are termed permanent gels. Pluronic F-127 (Poloxamer 407, PF-127) is a thermoreversible gel (3-6).
