Is it possible to use MaXtract for an organic extraction with a mixture of phenol and BCP (1 bromine chlorpropane)?

Yes, this application is possible with both MaXtract Low and High Density Tubes. A sufficient quantity of BCP should be used when using MaXtract High Density, in order to achieve a stable gel phase. BCP increases the density of the organic phase in the same way as chloroform.
